Key Benefits

- Inner bag offers standalone comfort in 20–35°F conditions—the perfect bag to take along on hut trips, back-of-the-truck adventures or couchsurfing on your way to fun
- Outer bag offers standalone comfort in 45–50°F conditions—a packable yet lofty option for warm nights backpacking, bikepacking or packrafting
- Combine the inner and outer bags to create a temperature-controlled sleep space for trips with variable conditions, down to 0–15°F
- Modular, ultralight bag design stays attached to your sleeping pad, so you won't roll off in the middle of the night

- Maximum thermal efficiency is achieved when inner and outer bags are layered, using offset quilted construction to minimize cold spots
- Sleep on either side using the inner bag alone or within the outer bag; 3/4-length, anti-snag ambidextrous zipper stays out of the way when side sleeping
