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.

Description
A lightweight tarp shelter with integrated bug protection
Take our 1P Cirriform Tarp, sew in perimeter bug netting, and what do you get? The 1P Cirriform w/ Bug Skirt, built for trips with low to moderate bug pressure on bare ground when you don't want to carry a separate inner.
For more on the tarp itself - geometry, materials, pitching - see the 1P Cirriform Tarp page.
What the skirt adds
- Integrated perimeter netting - 0.6 oz no-see-um netting sewn around the base for built-in bug protection; adds ~2.4 oz (68g) over the standard Cirriform
- No separate inner required - works as a standalone shelter for low to moderate bug pressure
- Corner stake loops - four loops at the base to pin the skirt for a better seal in breezy conditions or on uneven ground
- Inner-compatible - accepts the Y-zip Bug Bivy or 1P Bug Shelter inside for bug heavy trips
- Floor-compatible - works with any groundsheet or our tub-floor (a purpose-built integrated floor is in development)
What to know before you buy
- Breezes can lift the netting - Fortunately, the windier it is, the fewer bugs tend to be out.
- In wet, windy conditions, water can blow off the netting - Pitching low or staking down the netting will help, and with the netting not blowing around, it'll actually help block some splashing.
- Getting a seal on vegetation - If you're camping on lumpy ground or tall grass, expect some gaps around the perimeter.
- There's a small gap in the netting at the end of the zipper - A known limitation of the current design.
- Staking the four corner loops improves the seal - but it adds 4 stakes to your kit.
First batch note: The tie-out loops on this batch were added after initial construction and may be slightly harder to use than they'll be in future production runs. They work, they're just not as refined as what's coming. We're offering a 5% discount on this batch to reflect that (automatically applied).

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.

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: 37"–44" (94–115 cm)
- Rear Pole: 26"–33" (66–84 cm)
- Stakes: 6 (8 for better wind stability)
Pitching
How to pitch the Cirriform
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.

High quality toy loved by my dogs
Color: Brown, Pattern Name: Tree stump 2 Pack
These are amazing, my dogs favorite toys now. I have two strong chewers who haven’t been able to destroy these. I use yogurt, peanut butter and eggs, broth, really any dog friendly liquids to fill it. I recommend these to all my friends and family with dogs of all sizes.

Excellent Purchase!
Color: Brown, Pattern Name: Tree stump 2 Pack, Color: Brown, Pattern Name: Tree stump 2 Pack
My dogs and I really like these treat toys! I was surprised and questioning whether to keep them when I took them from the box. They are heavier and harder and larger than I envisioned. I didn't realize how hard a nylon/coffee wood combo actually is. However, I want to emphasize that the sales description IS accurate. It details the specifications, materials and size. Clearly states that they are designed specifically for aggressive chewers. I just haven't purchased anything quite like this before.
That said, I was happy it came in a 2 pack and it seems a good value for the price. The dogs have chewed on them, I can see the marks, but they haven't made a dent after about 6 treat sessions. These logs are at least as hard as antlers. They will last a long time. The silicone trays are easy to fill and freeze. I made low calorie popsicles with bone broth and some added mix-ins like pureed pumpkin, healthy freeze dried dog food topper sprinkle, etc. You could also add some peanut butter in the small open end of the log if you want. I just ran hot water over the bottom of the silicone tray to melt the freeze slightly and the frozen treats slid right out. They are shaped perfectly to fit the hole in the log. The seller provided small tools to unscrew/screw the cap in and out for filling with treats.
Even the smaller of my 2 dogs (30 lb Brittany) can get her mouth around the end of the log to carry it to her bed to lay and lick/chew it. I guess another advantage, beyond the durability, of the material is that my dogs don't want to play with it like a toy. They know it is time to relax and have a treat timeout. More like chilling with a chew bone.
Overall we really do love these!! Glad I tried them.

Great Product!
Size: Medium, Color: green, orange, pink, Pattern Name: clean tuff bone bacon
My dogs love their dental chews! This product is durable and the perfect size for each of my dogs. I've purchased two of them (medium and large). One of my dogs is an aggressive chewer and this product is holding up. Hartz makes great pet products. I'm very happy with the product.
