Single-wall Design

Perfect for hikers on-the-go. Our Cirriform SW (single wall) is loved by thru-hikers and minimalists for its simplicity. With its one-piece design, just pitch the fly and you’re done - no fussing with multiple tent pieces and cords at the end of your long day on the trail. A compact footprint lets the shelter slide into tight spaces with ease while maintaining a surprisingly spacious interior.

A unique, two-point beak provides extra vestibule space at the front of the shelter while the integrated bathtub floor and no-see-um mesh provide protection from everything you want to keep out. Our ‘OSAS’ system provides a quick way to cinch the side mesh panels shut. It’s a great way to block out a cold breeze in the middle of the night (video).

  • One-piece design keeps pitching simple.
  • Compact footprint slips into tight spots.
  • 2-point beak maximizes vestibule space.
  • Zippered vestibule rolls completely out of the way.
  • Integrated no-see-um mesh and tub floor keep nature out.
  • 'OSAS' System blocks wind/spray without pitch adjustment (video).
  • Two interior stash pocket and hang loop for your odds and ends.
  • Reinforced Dyneema Tie-outs for long life
  • Taped seams on Dyneema fly never need sealing.
  • Lineloc tensioners at tie-outs for easy pitch adjustment (removable).
  • UHMWPE Core guyline with reflective tracer included.
  • Made in the USA by hikers for hikers!
  • FREE Domestic Shipping.
  • Please note that the photos of the shelter in the field show this shelter made with a SilPoly floor.

To maximize weight savings, we pair an ultralight .8 oz Dyneema rain fly with a durable 1 oz Dyneema floor to build a protective shelter that will last.
