MonoLite – Ultralight Efficiency for Fast-Packed Adventures

For true minimalists, the MonoLite delivers exactly what you need—nothing more, nothing less. Designed for bikepackers, fastpackers, climbers, and racing enthusiasts, this ultra-efficient sleeping bag is stripped down to the essentials. The microbaffled construction prevents cold spots, while the half-length lightweight #3 coil zipper keeps weight to an absolute minimum. An insulated top collar and draft tube add just enough warmth where it matters most. With its PFC-free DWR-treated 10D nylon shell and a pack size comparable to a Nalgene bottle, the MonoLite is built for those who move fast, sleep light, and demand performance.
