Shrike

Designed for Movement

The Shrike is a smaller, more compact version of our Sassafras Fastpack, built specifically for mountain running. It sits higher on the back, with vest-style shoulder straps and generous pockets to keep more of your gear within reach. Every pack is cut and sewn in our Bonner, Montana workshop.

• Add-on items (available separately)

Adjustable Volume

The Shrike's main compartment adjusts from about 6.5L to 24L, with four basic configurations.

The tapered width and thickness follow the body's form for a more natural weight distribution and feel.

Max Volume: ~24L

The extension collar fully extended, about 3 rolls of the roll-top.

Ideal High Volume: ~12-18L

The roll-top secured anywhere from the level of the shoulder straps to just above the zipper access.

Reduced Volume at Base

The bottom of the pack clipped to taper the base. If you prefer a more aggressive taper into your back:

1. Fasten the buckles on the bottom of the pack.
2. Relocate two of the hooks from the shock cord to the loops on the daisy chain to secure the bottom near the center.

Ideal Low Volume: ~6.5L

The rear panel folded away to create a smaller pack.

1. Use the g-hooks to fold away the rear panel.
2. Cinch the shock cord and store the extra in a pocket to keep it tidy.

Pockets

Shoulder strap pockets

The main shoulder strap pockets are accessible from the top or the side. They're useful for carrying all sorts of things like water bottles, phones, hats, snacks, and so on.

• Top access via cinched opening
• Side access via zipper
• Elastic compression straps help hold items in place and reduce bounce of partially filled soft water bottles.
• Secondary outer mesh pockets for quick access to small items like snacks, gloves or a hat.

Side & Main pockets

The side pockets are made of stretchy fabric. Because the pack sits so high on the back, don't expect to reach these pockets while you're wearing it.

Bottom Pocket

The bottom pocket sits at the base of the pack, and you can reach into it from one side while you're wearing it. It's a handy spot for snacks and small items, a wind or rain layer, or overflow gear that doesn't fit in the main compartment.

• Made from stretch mesh

Pockitos

The small pockets on the shoulder straps are called "Pockitos." Two are located where the straps meet the pack and sit on top of or just behind the shoulder. The other two double as load stabilizer mounts and sit just above the main shoulder strap pockets, from the upper chest to near your shoulders. Examples of what might be carried in them include rain pogies, energy gels, lip balm, a mini satellite communicator, a small knife, a whistle, or a headlamp.

• 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 of the pack body is a readily accessible place to securely stow your keys and wallet during your trip.

• #3 Aquaguard, water resistant zipper
• Recycled 20D silpoly backing
• Internal clip for keys

Features

Hydration/Stash Sleeve

A zipper located above the shoulder straps gives easy access to an internal sleeve and the pack body. The zipper opening doubles as a hydration hose port on the right side, and an elastic band on the shoulder strap keeps the hose in place. When running with minimal gear, stow your items in the sleeve to keep them closer to your back.

• #3 Aquaguard, water resistant zipper
• A bladder hanger is provided: 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 the opening when the hose is in use.
• Sleeve is made from Recycled 20D silpoly.

Load Stabilizers & Y-strap (removable)

Load stabilizers work with the Y-strap to help you adjust how the pack carries. Tightening the stabilizers pulls the weight closer to your back to secure it in place. Loosening them reduces constriction. Their benefit is more noticeable with larger loads and increased body movement. For lighter loads, we often leave them at home and attach the center compression strap directly to the buckle at the haul loop.

Shock Cord Lashing/Compression (removable)

The shock cord on the rear panel provides compression and lashing options. Removable hooks allow you to customize it as needed, and loop webbing on the sides lets you secure tall items, such as tent poles, in your side pockets. To secure an item, wrap one of the free ends of the cord around it, then clip the hook to the webbing.

Shoulder Strap Padding (removable)

The shoulder strap padding is removable, so you can swap in a different thickness, replace it when it's worn, or take it out completely. Removing the padding enhances breathability and helps the straps conform to your body, but we only suggest doing this for very light loads.

Available in 3/8" (included), 1/4" and 1/2" thicknesses.

Center Compression Strap (removable)

The strap that goes across the top of the pack is removable so you can swap out different lengths. For example, when used in vest mode, swap the strap out for a shorter length. It can be clipped directly to the pack or to the main pocket at the bottom, and near the haul loop or Y-strap at the top.

What's Included

• The pack body
• Y-strap & load stabilizers for tweaking pack carry characteristics
• 2 sternum straps (shock cord style)
• 3/8" shoulder strap padding
• Center compression strap

The sternum straps are modular: the included shock cord style straps give elasticity and good rebound, and static straps are available separately.

Specifications

Capacity

Volumes are approximate. Pockets are made with stretchy fabric, so pocket figures represent the fabric stretched, but not maxed out.

Weight

Total weight is the pack with all included items; bare pack is the pack with all removable items taken off. Weights can vary somewhat batch to batch and by color.

You'll notice the Ultra100x pack comes in heavier than the UltraGrid pack despite using a lighter fabric. The weights above reflect what we're actually seeing on finished packs.

Removable items (removing these reduces the spec'd pack weight)
