    Lightweight and Warm.

    Offering you the best of both worlds, the Big Agnes Flume UL Sleeping Bag: 30 Degree Down provides dependable and lightweight warmth, making it an ideal companion when every ounce counts. The Flume UL features a traditional mummy silhouette that minimizes the bag's overall weight and maximizes its thermal value, while the nylon exterior and lining are highly abrasion-resistant and assure ample breathability when you need it. Additionally, the nylon shell is equipped with a DWR treatment that fends off light moisture and precipitation.

    As for the insulation, the 850-fill DownTek provides adaptive warmth, unimpeded breathability, and creature-like comfort. The down insulation is not only RDS certified, but it's also water-repellent and free of fluorocarbons. Meanwhile, the body-mapped thermal construction provides optimal thermoregulation thanks to its vertically structured, contoured side walls. This design allows the bag to trap warmth closer to your body and circulate it more effectively within the confines of the bag. An ergonomic foot box is designed as such that it retains loft and warmth, and the 3D anti-snag draft tube prevents heat loss through the main zipper.

    • Draft tube seals out cold and seals in body heat
    • Interior fabric loops for sleeping bag liners

    UL Traditional Down Mummy Sleeping Bags

    These technical ultralight bags are designed for adventures where every ounce counts, each nook and cranny in your pack is accounted for, and you depend on the performance of your sleeping bag like you would a harness, helmet, or beacon.

    Yukon Territory Approved

    • Familiarity: I've used it several times

    I recently purchased and used this sleeping bag for a backpack hunting expedition in the Yukon Territory. It is incredibly light, packs down small, and kept me very warm in below freezing temperatures for a 10 day trip.
