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.

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.

Got it for my college class, it was a required text.
Format: Paperback
Got this book for one my college class, no joke this was a required text. But overall it was an okay read, only reason why I gave it a 4 out 5 is because I prefer to read books for enjoyment and interest, reading a book for class takes that away.

Superman, a Dark Knight in the Skies
Format: Paperback
This is a beautiful tome of the first issues of Superman under Action Comics and the first Superman issue. Although providing the same texts of Chronicles, I find this series better because they have more issues per volume. In spite of its 390 pages, these volumes are light and easy to handle. Albeit the simplicity and innocence of these stories, Superman impresses me as a "dark knight" of the skies given his toughness with the bad guys. In these stories, he's got no compassion for criminals. He also defends the working class, stand for fair treatment of workers, and even takes an "isolationist" stance which was popular in the days before WWII. Another surprise for the first-time reader of this period is that Superman can't fly; he can only leap over tall buildings. There is no Krypton and no Daily Planet. The city of Metropolis is introduced for the first time in the second half of this tome. And Lois Lane is often relegated to unimportant journalistic tasks, while she has greater ambitions. It is a great experience to read these old stories in a beautifully designed tome. I hope they reproduce the others quickly.

This is Superman like you DON'T remember him!
Format: Kindle
I've been a fan for as long as I've been able to tie a bath towel around my neck, so diving into these early comics has been a real joy! The character was quite different in the beginning so if you're not familiar with Golden Age Superman this might be quite the eye opener. Here in these early comics, Supes certainly isn't the Big Blue Boy Scout you knew and loved in the Silver Age and beyond; early on, he's more like the Well-Meaning Big Blue Bully/Borderline Sociopath. Sort of like early Golden Age Batman: bad guys die, Superman (or Batman) kind of shrugs and thinks, "Well, they got what they deserved..." His relationship with Lois is a bit more desperate-seeming in a few places as well. In fact, he's almost a bit stalker-ish in his pursuit/attitude toward Miss Lane. You can thank DC editor Whitney Ellsworth and a few others for softening the rough edges and turning The Man of Steel into the virtuous character we have today.

This is my Superman
Format: Paperback
Before super villains came along, Superman fought corrupt businessmen and world leaders. In this volume, you get stories like Superman trapping a wealthy mine owner in his own mine so he can feel what it’s like for his exploited workers (as I type that, I thought of a great parallel that might get this review removed haha), forced warring leaders to settle their differences in person, and destroyed a ghetto to get the government to pay to give the poor people modern housing (today our government would just leave them homeless but I digress)
At some point in this volume, you get the first supervillain and it gradually goes away from this great Superman at that point but this Superman is my Superman, rough scripting/art and all
