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.

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.

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):

Pitching
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.

Westies Fav
Size: Small, Pattern Name: Pack of 1
Best Westie ball ever, my dog loves this ball. Exactly her size! 3" tennis balls are too big & she rips the fur off. this silicone-ish ball has no fur & is 2&1/2 "
We have 2" balls from her electronic ball laucher, but she still loves this glow in the dark best!

Best dog ball in the world!
Size: Large, Pattern Name: Pack of 1, Size: Large, Pattern Name: Pack of 1
My dog is singularly obsessed with playing ball. He would drop a steak to chase a ball. (He'd return to the steak, but not without the retrieved ball. He's not an idiot.) He makes dangerous leaps, crashes into trees, and runs fast enough to catch thrown balls before they even hit the ground. Since he doesn't care about his own wellbeing, it's my job to protect him as much as I can. And a lot of balls are hard enough to cause him pain or dental damage when he mistimes a catch. Enter the ChuckIt Glow Ball!
The minute Cowboy got his first Glow Ball, he no longer had any interest in the dozens of tennis balls scattered around the house and yard. If I took the Glow Ball away and instead threw a tennis ball, Cowboy would run to retrieve the ball, then return without it and begin looking all over the house for the Glow Ball. The Glow Ball is tough enough to survive Cowboy's big, sharp chompers, yet it's soft enough to do no harm when it hits him in the face. The glow feature is a huge bonus, too. Cowboy gets distracted by chipmunks and squirrels when we're playing, so he sometimes can't remember where he dropped the ball to pursue the interloper. If the ball was exposed to enough light before it was misplaced, it will be easy to find once the sun goes down. (Otherwise, Cowboy always finds it eventually.) When I'm feeling nocturnal, I'll put the ball under a light for a few minutes to activate the electrons, then treat my boy to a middle-of-the-night game of fetch.
I was so happy to see these on sale, I bought a lifetime supply for my pantry. The size guide seems accurate. ChuckIt recommended the large size for a dog of Cowboy's weight and that size is perfect. Highly recommended product.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value.
By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference.
Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design.
Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.

Great ball for heavy chewers
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Great toy for my Doberman. She chews through tennis balls in about 15 minutes but these are very durable. She likes to chase them but also just chew on them.
