YAMA 1P Cirriform Tarp - SilPoly

The 1-Person Cirriform is the culmination of over a decade of thoughtful refinement, engineered specifically for the discerning adventurer who demands performance, reliability, and efficiency. Crafted from recycled Silpoly fabric with dual-sided silicone coating, the Cirriform excels at shedding wind and rain while resisting sagging and water retention, ensuring a taut, protective pitch even through challenging conditions and temperature fluctuations.

Versatility defines the Cirriform. With its uniquely configurable dual-entry system—allowing easy front or side access—changing your entry style is as simple as repositioning a single clip. Front-entry provides maximum protection from precipitation, while side-entry enhances convenience and offers effortless ingress and egress. Clear nights reward users who roll back the side panel, inviting stargazing right from the comfort of their sleeping bag.

Enhance the Cirriform’s performance further by pairing it with your favorite inner tent or bivy, effortlessly transforming it into a lightweight double-wall shelter. Thoughtfully placed interior hang loops facilitate quick and secure attachment points for Yama Mountain Gear’s own Y-zip Bug Bivy or 1P Bug Shelter—as well as other popular inner shelters—ensuring comfort and protection from insects and ground moisture. Additional loops near the tarp corners help maintain floating tub floors suspended neatly when pitched low, maximizing usable internal space.

Built to be ultralight yet robust, the Cirriform utilizes trekking poles for support, accommodating a wide range of pole lengths at both the front (94–112 cm) and foot ends (66–84 cm). Thoughtful details—including reflective tie-outs, durable water-resistant zippers, pre-installed guy lines with tensioners, and strategic vestibules—complete this refined shelter. Whether tackling fastpacking trips, long-distance thru-hikes, or chasing ambitious FKTs, the Cirriform reliably delivers compact portability, uncompromising protection, and unmatched versatility.

Seams aren't sealed. We recommend to use GEAR AID Seam Grip SIL seam sealer to achieve complete waterproofness. We do not offer seam sealing service at this time. It is important to note that seam sealed products can no longer be returned within 30 days. However, the product is still under warranty.
