Description The Western Mountaineering DreamLite 35 Degree Sleeping Bag is an ultralight down sleeping bag designed for warm-weather backpacking and fast-moving backcountry trips where pack weight matters most. Rated to 35AdegF (2AdegC), it provides dependable three-season performance from late spring through early fall. Insulated with premium 850+ fill-power goose down, the DreamLite offers exceptional warmth-to-weight efficiency and compressibility, packing down to roughly the size of a water bottle for easy carry in ultralight packs. Fully baffled construction maintains loft and minimizes cold spots, while the 12D ExtremeLite(TM) ripstop nylon shell balances durability, breathability, and minimal weight. A roomy semi-rectangular shape provides extra space for side sleepers, and dual zippers allow the bag to vent heat or open flat like a quilt, making it a versatile sleep system for mild backcountry conditions.
