A versatile option for 3-season backpacking, the Big Agnes Bolten SL 20 Degree utilizes high-performance synthetic insulation to balance weight, compressibility, and all-condition performance.
The bag is insulated with a mix of premium PrimaLoft Silver and PrimaLoft Gold Active insulations, ensuring that you get consistent warmth even in wet or damp conditions. Insulated, stretch side wall panels maintain warmth while offering a close fit without inhibiting mobility inside the bag. A nylon rip-stop shell with a water-repellent finish further protects the insulation from moisture while providing lightweight durability.
Other features include a thermally-efficient mummy-cut, an insulated and contoured hood, and a draft tube that runs the length of the 70" zipper to lock in heat and keep out cold air. Integrated internal loops enable you to use the bag with a liner (sold separately).
Available in Regular (fits to 6' 0") and Long (6' 6") lengths, each Big Agnes Bolten SL 20 Degree sleeping bag includes a mesh storage sack and a nylon stuff sack.
