In an 80% relative humidity environment, an untreated 15-degree down sleeping bag loses up to 30% of its loft over a period of eight hours. A 30% loss of loft essentially turns a 15-degree sleeping bag into a 30-degree sleeping bag. DwrDown™ sleeping bags avoid this loss of thermal efficiency by retaining 98% of their loft, keeping you warmer all night long on both short and extended trips into the backcountry. DwrDown™ sleeping bags represent the evolution of down insulation.
Stuffed full with 800-fill hydrophobic DwrDown™ insulation, the BTU -20 is made with a Drizone waterproof/breathable membrane for maximum warmth and comfort in even the coldest, wettest environments.
Cold weather overnights have never been more comfortable. The BTU -5 is insulated with 800-fill hydrophobic DwrDown™ and made with a Drizone waterproof / breathable membrane for outstanding warmth and comfort on cold, wet overnights.
