The 1P Cirriform Tarp - a lightweight tarp shelter for hikers on the move
The Cirriform is for hikers who want to spend most of their day, well, hiking. Whether you're a seasoned ultralight tarp camper or making the jump from a freestanding tent, it delivers solid weather protection and an intuitive setup. With multiple inner options to adapt to your needs and the season, the Cirriform pitches fast, packs small, and holds its shape when the weather gets rough. It's the shelter we reach for on high-mileage days when the weather is unpredictable, and setup needs to be automatic and adaptable.
Performance
The shaped geometry and Silpoly fabric work together to keep the pitch taut through the night. Silpoly resists sagging when wet, so you're not re-tensioning at 3am. The curvature handles wind and sheds rain without requiring a perfectly flat campsite. When bugs or condensation are a factor, pair it with one of our inners to run it as a full double-wall setup.
Dual Entry
The Cirriform has two entry points, and each has a purpose. The side entry is the everyday option - easy to get in and out, and on clear nights, we love rolling it back for a view of the stars. Use the front entry to keep the sleeping area covered when weather moves in. Switching between them is as simple as moving a clip.
Pair it with an inner
The Cirriform pairs with a bivy, net-tent, or floor to create a modular double-wall shelter you can adapt to the season and conditions. We make three inners designed for it: the Y-zip Bug Bivy, the 1P Bug Shelter, and the Tub Floor. Most other brands' inners will work too. The Cirriform DW bundles the tarp with the Bug Bivy or Bug Shelter at a discount.
Trekking pole supported
Pitches with your trekking poles or tent poles. The Cirriform accommodates front poles from about 37" to 44" (94-115 cm). Poles of 26"-33" (66-84 cm) are best for the foot end, though longer poles can be adapted.
Optional pole sets are available for those who prefer to travel without trekking poles.
Notes/FAQ:
- Do I need a groundsheet or inner? That's up to you, but if you're not using an inner, you'll probably want to use a groundsheet or floor.
- Do I need to seal the seams? Tarp seams should be sealed using a sealer for silicone coated fabrics (we recommend Seam Grip +SIL by Gear Aid). Optional seam sealing service available.
Made in Vietnam and field-tested in Montana

Recycled, 20D Silpoly
The Recycled 20D Silpoly fabric uses a silicone-based coating on both sides. Silpoly absorbs less water than silnylon, reducing surprise weight, while lower sag ensures the tarp stays taut through the night.

Seam sealing: Due to the silicone coating, the seams cannot be taped and need to be manually sealed with seam sealer. You can do this yourself or use our seam-sealing service. Seam sealer is available here, and more information can be found on our Seam Sealing page.

Overall tarp dimensions for various pitches:
Click to enlargeHang loops
Hang loops for suspending inners are placed under each apex and near the corners. When pitched low, the loops help keep floating tub floors elevated - just run the corner lines through the loops before clipping to the tarp.
Required items (not included):
- Front Pole: About 44" - 45" (~111 - 114 cm) if pairing with the Bug Shelter or 39" - 42" (~99 - 107cm) if pairing with the Bivy
- Rear Pole: At least 31" (~79cm) if pairing with the Bug Shelter or at least 26" (~66cm) if pairing with the Bivy
- Stakes: 6 (8 for better wind stability)
How to pitch the Cirrifrom
Start by staking out the corners of the tarp to establish your base. Raise the poles at the peaks and stake them to form the shelter's shape. Adjust and tension the lines evenly for a tight, balanced pitch.

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.
Shipping Information
While most orders ship out within 1 - 3 business days, please allow up to one week for us to ship your order. This gives us some scheduling flexibility for getting out on the trail!*
*If you select seam sealing services with your purchase, please allow a few extra days for us to seal the item(s) and ship your order.

We use USPS and UPS for domestic shipping.
