Overview
Meet the sleeping bag that does more with less: a limited-edition Cumulus Aerial 330. Weighing just 17 oz and rated for 30°F, it ditches the extra down on the bottom (your sleeping pad’s got that covered) and skips the zipper for max performance. Designed with 900 FP down and sleek Toray Airtastic® fabric, it’s a minimalist’s dream for outdoor adventures.
