Yama Mountain Gear Cirriform 1 SW Cuben Fiber

The Cirriform 1 SW is YAMA Mountain Gear's minimalist single-wall solo shelter, pitched with one trekking pole and built entirely from 0.8 oz DCF (Dyneema Composite Fabric) in a seam-free construction. At 294 g total (246 g minimum trail weight for the fly alone), it sits firmly in the ultralight category, though the single-wall design means no separate bug mesh — condensation management depends on ventilation and pitch technique rather than a dedicated inner layer. The floor measures 229 × 155 cm with 155 cm at the head and 127 cm at the foot, roomy for a solo tent of this weight, and the single side-opening door with a waterproof #5 zipper leads to one vestibule for gear storage. Ten guy points with reflective lines and six stakes support a taut, wind-resistant pitch, and eight interior pockets are generous for organization in a tent this light. Built for thru-hikers who prioritize weight over the extra protection of a double-wall or freestanding design, and who are comfortable managing condensation in a single-wall DCF shelter.
