Designed for Movement
The Sassafras Fastpack is designed for activities demanding stability and freedom of movement. It syncs with your motions, riding comfortably with minimal bounce over a wide range of loads.
Pockets up front provide on-the-go access while the tapered profile keeps the pack out of the way. Every pack is hand sewn from imported fabrics in our small workshop in Montana.
The 3rd generation of the Sassafras (current version is V3.1) provides improved fit & comfort, and increased performance, especially in vest mode.
Features:
- Variable volume from vest to small backpack.
- Running vest inspired shoulder straps provide comfort and stability.
- Dual sternum straps provide adjustable securement.
- Large shoulder strap pockets hold a variety of items.
- Removable load stabilizers for tweaking weight distribution on the fly.
- Tapered shape follows the form of the body.
- Zippered hydration/stash sleeve (optional).
- Zippered side pocket provides a secure place to store keys and wallet (optional).
- Pack body fabric made from recycled materials.
Included items:
- The pack body
- Y-strap for tweaking pack carry characteristics

- Feed bag (attaches to hip belt)
The above items may be discussed in the product description and shown in the photos, but are sold separately.
Versatile Configurations
The Sassafras offers a range of configurations. Dial it in for your long trail run one day and take it out for your lightweight backpacking trip the next weekend.
For example, a great weekend for us might mean backpacking to camp on Friday so we can spend Saturday trail running deep in the mountains. With the Sassafras, we can hike to camp, then collapse the pack into a running vest for the next day's adventure.
The pack body’s volume adjusts from as little as about 4 L, to as much as 30 L (~38 L including the exterior pockets). The tapered width and thickness follow the body’s form, narrower and thinner towards the base, and thicker around the chest for a more natural weight distribution and feel.
See the 'Videos' tab for a demonstration.

Add-on items:
(available separately)
Pockets
Shoulder strap pockets
The main shoulder strap pockets are accesible from the top or the side. They're useful for carrying all sorts of things like water bottles, phones, hats, snacks, and so on.
Note: The custom Sassafras allows you to choose your preferred side for the key pocket, or to omit it.
- Top access via cinched opening
- Side access via zipper
- Elastic compression straps helps hold items in place and reduce bounce of partially filled soft water bottles.
Side & Main pockets
These pockets are made from stretchy fabric with an oversized & elasticized top. This allows for good volume while retaining a slimmer profile.
Note: The custom Sassafras offers an additional pocket style with more volume.
-Back to menu-Pockitos
These small pockets on the shoulder straps can hold a variety of items. They are installed at four locations. The lower location overlaps a bit with the main shoulder strap pocket with the opening about 2” above the top of the shoulder strap pocket. The upper location is at the shoulder and runs into where the strap connects to the pack. Note that items protruding from the top of the main shoulder strap pockets may interfere with use of the pockitos at the lower locations.
Examples of what might be carried in the pockitos include: rain pogies, energy gels, lip balm, mini satellite communicator, small knife, headlamp, etc.
Note: The custom Sassafras allows you to choose which, if any, pockitos you wish installed.
- Made from lycra mesh
- About 4" deep
- Locations: Top of shoulder straps (2), Mid-shoulder strap (2)
Key Pocket
This zippered pocket on the left side (from the wearer's perspective) of the pack body is a readily accessible place to securely stow your keys and wallet during your trip.
Note: The custom Sassafras allows you to choose your preferred side for the key pocket, or to omit it.
- #3 Uretek, water resistant zipper
- Recycled 20D silpoly backing (when Ecopak is the pack fabric)
- 1 oz DCF backing (when Ultra is the pack fabric)
Features
Hydration/Stash Sleeve
This zippered sleeve helps to keep a water bladder, or other contents, up against your back and separate from the main compartment. In running vest mode, you can access items in the sleeve more readily than items in the main compartment. The zipper opens on your right side and there are elastic bands on the right shoulder strap to help keep your hose in place.
Note: The custom Sassafras allows you to choose your preferred side for routing the hose, or to omit the sleeve.
- #5 Uretek, water resistant zipper
- A bladder hanger is provided. To use, pass the g-hook through an opening on your bladder and clip it back to the webbing it's mounted on (may not work with all bladders).
- Zipper garage covers opening when hose is used.
- Recycled 20D silpoly backing (when Ecopak is the pack fabric).
- 1 oz DCF backing (when Ultra is the pack fabric).
Ice Axe Loop
The optional Ice Axe loop consists of a ⅜" Nylon webbing loop at the bottom and ⅛" shock cord cinch at the top to ensure your axe stays secure. The upper cinch has two ‘hooks’ that when not securing an axe, can be used to secure tall items in the side pocket.
Note: The custom Sassafras allows you to choose your preferred side for the axe loop, or to omit it.
-Back to menu-Load Stabilizers (removable)
Load stabilizers help you tweak how the pack carries. Tightening the stabilizers sucks the weight in closer to your back to better lock it in place. Loosening them reduces constriction. We use them mostly when carrying larger loads when the extension collar is extended above the shoulder straps. When carrying small loads, we often leave them at home and clip the center compression strap directly to the haul loop.
- Accounts for ~0.60 oz (17.0g)
Shock Cord Lashing/Compression (removable)
The shock cord on the rearmost panel provides compression and lashing possibilities. Hooks on the cord allow you to configure it as needed, and o-rings on the sides allow securement of tall items, like tent poles, in your side pockets (wrap one of the free ends of cord around the item, then clip the mitten hook to the o-ring). Shorten the cord to taste, or remove if not needed.
- Accounts for 0.76 oz (21.5g)
Center Compression Strap (removable)
The strap that goes across the top of the pack is removable/interchangeable to allow you to swap out different lengths. For example, when used in vest mode, swap the strap out for a shorter length.
Note that the g-hooks that we use (and metal hardware in general) is hard on webbing so you may see this strap start to wear quickly. Making the strap removable allows easy replacement if needed.
- Accounts for 0.3 oz (8.4g)
Add-on items
These add-on items are available separately.
Hip Belt
For more substantial loads, the hip belt helps to secure the pack and dial in how it carries. It's also compatible with our modular accessories for increased functionality.
We highly recommend the use of the hip belt for most users. We've known many people who once swore off hip belts who now won't go without it.
- Adds about 2.2 - 3.3 oz (62 - 94g) depending on size & material
- See the product
Hip stabilizers
The hip stabilizers help restrict movement of the bottom of the pack and improve load transfer when tightened. Loosening them, or removing/omitting them increases freedom of movement.
- Adds ~0.41 oz (11.6g)
- See the product
Side compression straps
Side compression straps provide an alternate way to secure the roll-top can improve stability.
- Adds TBD oz
- See the product
Feed Bag
A cinch top pouch for snacks or other small items like liner gloves or a hat.
- 0.75 oz (21.3 g)
- 1 L (70 in3)
- See the product
Bear Spray Holster
For those places where you want to carry bear spray, having it quickly accessible is crucial. Carrying it in one of the Sassafras’s shoulder straps works well, but uses up valuable space. Free up that space with this holster that attaches to your hip belt.
- 0.45 oz (12.7 g)
- See the product
Trekking Pole Stow
The trekking pole stow is a simple addition to the shoulder strap that facilitates the stashing of your z-fold trekking poles. We can install it for you, or you can install it later, if needed.
NOTE: We've updated the pole stash. While similar to what's shown, the cord routing is now a little different from that shown in the photos.
- Adds ~0.14 oz (4.0 g)
- See the product

Sizing Information
To determine the best pack size, it's important to get a good torso and chest measurement.
How to take the measurements
You'll get the best measurements with the help of a friend, but you can still get decent measurements on your own. Taking the measurements a few times to average the results is recommended.
Torso Length:
The distance along your spine from the C7 vertebra to the level of your iliac crest.
- Tilt your head forward and find the bony protrusion at the base of your neck. This is your C7 vertebra.
- Place your hands on your the top of your hips (iliac crest) with your thumbs pointed horizontally toward your back.
- Run a string along your spine from the level of your thumbs to the C7 vertebra.
- Measure the length of the string to determine your torso length.
Chest:
The distance around the fullest part of your chest.
- Stand up straight with your arms by your sides.
- Wrap a string or fabric tape measure around your chest at its widest point, a little below your armpits. This is usually over the nipples and across the shoulder blades.
- Breathe normally and try to keep the tape parallel to the ground.
- Measure the string or note the distance on the tape measure for your chest measurement.
Interpreting your measurements
Torso Length
- Generally you want to match the pack's torso length to your measured torso length.
- There is often a +/- 1" or so wiggle room.
- If you don't plan to add a hip belt, matching the pack's length to your torso is less important. Sizing down (1, maybe 2") is usually preferred over sizing up and may provide a better fit for runners.
Our highest confidence for a good fit occurs for torso lengths falling in the green region.
Chest Size
- Your chest size can affect how far down your front the shoulder straps extend.
- Chest size also affects the length of sternum strap and shoulder strap webbing required.
- Chest sizes falling in the green zone are most likely to fit well with the target torso length pack.
- For larger chest sizes, we do not recommend undersizing the pack's torso length. (see example 1)
- For smaller chest sizes, we do not recommend oversizing the pack's torso length. (see example 2)
- For larger chest sizes, you may benefit from going up a bit in torso length, especially if you fall in between sizes. (see example 3)
Our highest confidence for a good fit occurs for chest sizes falling in the green region.
- Example 1: You have a 19" torso and a 40" chest; we do not advise sizing down to an 18" pack. If you have a ~35" chest, you might be able to get away with it.
- Example 2: You have a 17" torso and a 33" chest; we do not advise sizing up to an 18" pack. If you have a ~37" chest, you might be able to get away with it.
- Example 3: You have an 18" torso and a 41" chest; you may be better off with a 19" pack.
Putting on the pack
When you have a good fit, the hip belt (if used) will sit on or just above your illiac crest and the shoulder straps will curve comfortably around your shoulder without significant airspace between it and your back.
- Start with the shoulder straps, stabilizers, and sternum straps loosened
- Put on the pack
- If using a hip belt, get the hip belt situated where you'd like it to sit.
- Snug up the shoulder straps but don't overtighten.
- Adjust the sternum straps to adjust where the shoulder straps lay (you may need to loosen the shoulder straps).
- Snug up the stabilizers as desired.
What to expect
As a fastpacking pack, the Sassafras may behave a bit differently from more traditional packs.
- The Sassafras is designed to distribute weight evenly to the body rather than routing weight to the hips. When your pack is light enough to allow for running, this provides the best performance. That being said, when hiking with heavier loads, some load transfer is desired and can be achieved by packing your pack so that the contents provide structure. Using hip stabilizers with the hip belt will help acheive even more transfer.
- You may find that the Sassafrass has a tendency to ride higher than other packs. This is most prevalent when the pack is low volume and/or when you're running with it. For the former case, it's because you've tightened down the shoulder straps to snug up the fit. In the later case, it's because during running, the pack unweights which causes the hip belt to lift off the hips slightly. Eventually, it will naturally nest in the waist rather than center on the hip crest. While users tend to notice this, it doesn't seem to bother them and should be expected with any pack (with a hip belt) when running. The hip belt's primary function is for load stabilization and additional functionality.
- Most people find that the Sassafras's ideal use case is found when it's loaded to ~15 - 22 lbs, with a mix of hiking and running. This sweet spot is where the pack truly excels.
- An often overlooked method for dialing in your pack's fit is to loosen the sternum straps so that you can tighten the shoulder straps. Inversely, if you feel that the pack is riding too high, try loosening the shoulder straps and tightening the sternum straps to compensate.

Bear Spray Holster
For those places where you want to carry bear spray, having it quickly accessible is crucial. Carrying it in one of the Sassafras’s shoulder straps works well, but uses up valuable space. Free up that space with this holster that attaches to your hip belt.

Trekking Pole Stow
The trekking pole stow is a simple addition to the shoulder strap that facilitates the stashing of your z-fold trekking poles. We can install it for you, or you can install it later, if needed.
NOTE: We've updated the pole stash. While similar to what's shown, the cord routing is now a little different from that shown in the photos.

Sizing info
Sizing Information
To determine the best pack size, it's important to get a good torso and chest measurement.
How to take the measurements
You'll get the best measurements with the help of a friend, but you can still get decent measurements on your own. Taking the measurements a few times to average the results is recommended.
Torso Length:
The distance along your spine from the C7 vertebra to the level of your iliac crest.
- Tilt your head forward and find the bony protrusion at the base of your neck. This is your C7 vertebra.
- Place your hands on your the top of your hips (iliac crest) with your thumbs pointed horizontally toward your back.
- Run a string along your spine from the level of your thumbs to the C7 vertebra.
- Measure the length of the string to determine your torso length.
Chest:
The distance around the fullest part of your chest.
- Stand up straight with your arms by your sides.
- Wrap a string or fabric tape measure around your chest at its widest point, a little below your armpits. This is usually over the nipples and across the shoulder blades.
- Breathe normally and try to keep the tape parallel to the ground.
- Measure the string or note the distance on the tape measure for your chest measurement.
Interpreting your measurements
Torso Length
- Generally you want to match the pack's torso length to your measured torso length.
- There is often a +/- 1" or so wiggle room.
- If you don't plan to add a hip belt, matching the pack's length to your torso is less important. Sizing down (1, maybe 2") is usually preferred over sizing up and may provide a better fit for runners.
Our highest confidence for a good fit occurs for torso lengths falling in the green region.
Chest Size
- Your chest size can affect how far down your front the shoulder straps extend.
- Chest size also affects the length of sternum strap and shoulder strap webbing required.
- Chest sizes falling in the green zone are most likely to fit well with the target torso length pack.
- For larger chest sizes, we do not recommend undersizing the pack's torso length. (see example 1)
- For smaller chest sizes, we do not recommend oversizing the pack's torso length. (see example 2)
- For larger chest sizes, you may benefit from going up a bit in torso length, especially if you fall in between sizes. (see example 3)
Our highest confidence for a good fit occurs for chest sizes falling in the green region.
- Example 1: You have a 19" torso and a 40" chest; we do not advise sizing down to an 18" pack. If you have a ~35" chest, you might be able to get away with it.
- Example 2: You have a 17" torso and a 33" chest; we do not advise sizing up to an 18" pack. If you have a ~37" chest, you might be able to get away with it.
- Example 3: You have an 18" torso and a 41" chest; you may be better off with a 19" pack.
Putting on the pack
When you have a good fit, the hip belt (if used) will sit on or just above your illiac crest and the shoulder straps will curve comfortably around your shoulder without significant airspace between it and your back.
- Start with the shoulder straps, stabilizers, and sternum straps loosened
- Put on the pack
- If using a hip belt, get the hip belt situated where you'd like it to sit.
- Snug up the shoulder straps but don't overtighten.
- Adjust the sternum straps to adjust where the shoulder straps lay (you may need to loosen the shoulder straps).
- Snug up the stabilizers as desired.
What to expect
As a fastpacking pack, the Sassafras may behave a bit differently from more traditional packs.
- The Sassafras is designed to distribute weight evenly to the body rather than routing weight to the hips. When your pack is light enough to allow for running, this provides the best performance. That being said, when hiking with heavier loads, some load transfer is desired and can be achieved by packing your pack so that the contents provide structure. Using hip stabilizers with the hip belt will help acheive even more transfer.
- You may find that the Sassafrass has a tendency to ride higher than other packs. This is most prevalent when the pack is low volume and/or when you're running with it. For the former case, it's because you've tightened down the shoulder straps to snug up the fit. In the later case, it's because during running, the pack unweights which causes the hip belt to lift off the hips slightly. Eventually, it will naturally nest in the waist rather than center on the hip crest. While users tend to notice this, it doesn't seem to bother them and should be expected with any pack (with a hip belt) when running. The hip belt's primary function is for load stabilization and additional functionality.
- Most people find that the Sassafras's ideal use case is found when it's loaded to ~15 - 22 lbs, with a mix of hiking and running. This sweet spot is where the pack truly excels.
- An often overlooked method for dialing in your pack's fit is to loosen the sternum straps so that you can tighten the shoulder straps. Inversely, if you feel that the pack is riding too high, try loosening the shoulder straps and tightening the sternum straps to compensate.

Product Availability
- In most cases, items that are available to add to your cart are in-stock and ready to ship. Please refer to the shipping tab or page for expected fulfillment times.
- Some items may be marked as "Avalable to backorder," "Made to order," and/or show a lead time. In these cases refer to the information on the product page for expected fulfillment times.
- For items that are sold out, please refer to the production calendar and the Q & A below for more information.
Q: When can I expect the item I'm interested in to become available?
A: For most items, please refer to the production calendar at the bottom of this page. This calendar shows when we expect to work on more substantial products. For some accessory products, production may not always be scheduled in advance and availability may be unpredictable.
FYI: If you do not see the item that you are interested in, then we do not know when it may become available (We're often not scheduled far out in advance and don't have a private schedule beyond what's shown!).
Q: Can I pre-order, back-order, or reserve an item?
A: We don't typically reserve products, however there are some exceptions to this. For example, if someone orders an in-stock Cirriform and wants to also order an out-of-stock Bug Shelter for it, if the Bug Shelter is expected within a couple weeks, we'll usually make arrangements to reserve one of the Bug Shelters and hold the order so shipping may be combined.
On occasion, select products may be available to back-order or pre-order. When this happens, that status will be shown on the product page. If you're signed up for the stock notification, you will receive a notice that the item is available to back/pre-order.
Q: Can you let me know when the item becomes available?
A: Yes. On the product page, enter your email address in the space provided to be automatically notified when inventory becomes available. If you don't see where you can do this, please let me know; sometimes there's a fluke in the settings and the field doesn't show. Please note that the email notification could get filtered out as spam. You can try to 'whitelist' info@yamamountaingear.com to make sure the email comes through.
NOTES ON USING THE CALENDAR
- For products shown on the calendar, you can typically expect the item to be made available towards the end, or soon after the period shown on the calendar. Sometimes, however, some items may be listed earlier in the period. For example, if the calendar shows that I'm working on tapered tarps, certain sizes may become available earlier within the period with other sizes coming later.
- Items that specify "ongoing production" mean that we are continually working on these items and doing our best to maintain inventory. If the item or a particular size is sold out, you can expect it to likely become available soon.
- Please note that you can change the month shown on the calendar using the arrows at the top.
