Big Agnes TwisterCane BioFoam Hiking Seat

The TwisterCane BioFoam Hiking Seat is a minimalist closed-cell foam pad meant for trailside breaks rather than sleeping — a small mat you sit on to keep cold or wet ground from soaking through your layers during rest stops, lunch, or cooking at camp. At just 57 g it is negligible in a pack, and its R-value of 1.7 reflects that purpose: enough insulation for short contact, well below what you'd want for an overnight sleeping pad. What sets it apart materially is the foam itself: a bio-based EVA compound made with more than 60% sugarcane-derived resin in place of conventional petroleum-based foam, aimed at hikers who weigh the environmental footprint of their gear alongside its performance. Measuring 51 x 30 cm with a 1.3 cm thickness, it has a dual-texture surface — smooth on one side, a dimpled tread pattern on the other — so you can flip it for more cushioning or more grip on angled or slippery seating. No stuff sack or repair kit is included, keeping the package as simple as the pad itself.
