The Big Agnes Women's Sidewinder Camp 35° carries the same 360-degree cocoon-style wrap as its colder-rated siblings, using FireLine ECO synthetic insulation and a manufacturer-rated comfort temperature of 2°C (35°F). At 1132 g with 812 g of fill, it sits at the warmer, lighter end of the Sidewinder Camp range, suited to summer trips and shoulder-season camping rather than freezing nights.
A center, full-length zipper and adjustable, fitted contoured hood handle temperature regulation, though this bag skips the draft tube of some siblings in favor of a simpler draft collar — a reasonable trade for a warm-weather bag where cold-air leaks matter less. The nylon ripstop shell and polyester taffeta liner, both treated with DWR, resist damp tent walls and morning condensation.
Included stuff and storage sacks make this easy to pack for car camping or backyard use, and PFC-free, recycled-content construction keeps it aligned with more sustainable materials. It suits campers who value the rotate-with-you comfort of the Sidewinder cut but don't need a bag rated for cold nights.
