Description
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.

A Dyadic Review: Baffling, Brilliant
Difficult. Rewarding.
Serious. Hilarious.
Wise. Faux-wise.
Scholarly. Mock-scholarly.
Observant. Absurdly, obsessively observant.
Sharp characterizations. Ridiculous characters.
Devout. Bawdy.
Endearing. Frustrating.
Genius. Barking mad.
Narratively incoherent. Stream-of-consciousness associative.
Consistently provincial. Profoundly universal.
Mired in the 18th century. Harbinger of 20th century literary Modernism.
Baffling. Brilliant
Not for every taste. For my taste.
And while I'm at it, let me give a shout-out for the out-of-print Norton critical edition, which provides many helps, essay avenues of understanding, and a clever chapter summary/table of contents. For so many years - since reading Moby Dick in grad school with the help of a Norton critical - this publication line has been my go-to for great texts: useful annotations, contemporary reviews, later scholarly articles, and more.
And also let me give a shout-out to Anton Lesser, who narrated the complete novel for Naxos. I have never, ever experienced an audiobook as masterfully produced and narrated as Naxos' Tristram Shandy. No, it is simply not a book one can listen to and fully comprehend as heard. But one might read while listening, or listen while reading, with - if you have the riight software - the narration sped up closer to one's own reading speed, and experience the full majesty of Lesser's absolute preparation, with Latin, Greek, French, and German - as well as regional English - beautifully and humorously intoned, character voices carefully differentiated, tone and mood captured, etc. Or, as I do, go for a walk and listen as you walk, and afterward slip into a comfy chair, crack the novel open, and continue from where you left off, or backtrack if necessary to sort out the characters. In any event, and particularly for devotees of audio books, do find Anton Lesser's note-perfect reading, a veritable radio serial, perhaps the last book you'd expect anyone to attempt single-handedly, with My Father, My Uncle Toby, Corporal Trim, Parson Yorick, Doctor Slop, Widow Wadman, and all the rest of the supporting characters beautifully, consistently interpreted. Lesser is, in a galaxy of fine narrators, the greatest I've heard: an absolutely peerless voice actor in a most demanding work.

Brilliant stream of consciousness style, *extremely* humorous
"The Life and Opinions..." is perhaps impossible to really classify. It purports to be a biography of the fictional Tristram Shandy, but I don't think you can call something a biography when it only covers a year or so of the subject's life! I would say that more than half of the novel actually falls into the "Opinions" referred to in the title. The rest consists of short stories on Tristram's father, uncle, and a couple other minor characters.
I have never in my life read so many digressions from the topic at hand, most of which were utterly irrelevant but the charm of it is that Sterne *knows* they're irrelevant, but mockingly expresses his license of authorship in forcing the reader to go off on these sidetracks. His attitude is: "If you can't wait a chapter or two to get back to the story, well, go take a flying leap, I'm the author." Sometimes the digressions are exasperating. Very unlike Victor Hugo's signature habit of digressing, say when a certain main character in Notre Dame decides to enter the Paris sewers, Hugo takes thirty or more pages to give a history of the design and construction of the Paris sewer system. At least Hugo's digressions have *something* to do with the story.
Well, maybe that's the problem. There isn't a main story in this novel. It's not a storybook. There are many short stories nested within the main framework, but there is no real protagonist or overarching theme of any sort. Indeed, the end comes abruptly and there is absolutely no resolution of any conflict.
It's not trying to teach anything, really.
So what is it? I'm not sure. More a comedy than anything else. Right up there with Dickens' "Pickwick Papers" in terms of humor, but lacking the story. Maybe funnier than Dickens and just as clever. I was rolling in the aisles so many times I lost count.
I read the Penguin edition, edited by Melvyn & Joan New. The back cover does a better job than I could ever do in providing a sense of what you're getting into when you pick this one up:
"No one description will fit this strange, eccentric, endlessly complex masterpiece. It is a fiction about fiction-writing in which the invented world is as much infused with wit and genius as the theme of inventing it. It is a joyful celebration of the infinite possibilities of the art of fiction, and a wry demonstration of its limitations."
It's a large work, it will take a while to work through. It's worth it. There are passages I want to go back to and make copies of to tape to the walls, they're that brilliant.

Interesting read, but takes some getting used to
I heard about this book on a blog, and figured I'd check it out. It's the rambling tale of a man determined to give you every last detail of everything that might be important to the narrative of his life. Unfortunately, he goes on tangets so often that he doesn't even get to his birth for several chapters, let alone the story of the rest of his life. Along the way, you're introduced to lots of random characters who are (at best) loosely related to the protagonist, but as often as not these tangents are fairly amusing.
The writing is pretty dense, and this along with the tangents had me putting the book down fairly often. It's probably ideal for a commuting book, but I never wanted to just sit down and blitz through big chunks of it.
Overall it's a very different kind of experience than a novel reader typically gets. It's worth a read for a change of pace, but I can't say it's a life-altering read.
