Windproof, waterproof, heat-reflective camping sleeping bag designed for cold-weather use. Key benefits Keeps you warmer: silvered nylon structure with an aluminum heat-reflective coating returns body heat and reduces heat loss in cold conditions. Protects from wind and moisture: durable mesh-nylon outer fabric is windproof and waterproof to help keep insulation dry and effective. Packs small, carries easy: compressible design reduces bulk for convenient storage in a backpack. Built to last: abrasion-resistant mesh nylon construction holds up to outdoor use and repeated packing. What it does and why you need it Reduces heat loss through reflective lining, so you retain more warmth during overnight stops. Blocks wind and shedding moisture so insulation performs better in exposed or damp conditions. Compressible form factor lets you carry reliable protection without occupying excessive pack space.
