Sleeping Bag

The Big Agnes Zirkel SL 20F Sleeping Bag is designed to deliver exceptional warmth and comfort in colder camping conditions. This mummy-style sleeping bag is insulated with 800-fill DownTek water-repellent down, which not only offers superior warmth-to-weight ratio but also performs well in wet conditions, maintaining loft and insulation properties. The ultralight, high-tenacity Pertex Quantum shell further enhances the bag's durability without adding unnecessary weight, making it an ideal choice for backpacking trips where every ounce counts. Additionally, the bag features a no-draft collar and no-draft zipper that work collectively to prevent cold air from sneaking in, ensuring a cozy night's sleep. The multi-section baffle construction optimizes thermal efficiency, keeping the down in place to eliminate cold spots throughout the night. For added convenience, the bag includes an interior fabric loop for sleeping bag liners and exterior loops for hang drying or storage. The Zirkel SL also comes with a mesh storage sack and a nylon stuff sack, making it easy to pack and transport. Whether tackling a chilly mountain trek or camping near frosty lakeshores, the Big Agnes Zirkel SL 20F Sleeping Bag promises a warm and restful sleep, even when the temperatures drop.
