The North Face - Furnace 20 / -7

Keep your inner furnace burning through the night with a compressible 600-fill ProDown™ insulated mummy bag that delivers reliable insulation when backpacking in wet, cold climates with temps down to 20°F. The North Face's three-season Furnace 20 is insulated with water-resistant ProDown™ that absorbs less water and dries faster than traditional down to keep you warmer when exposed to moisture. An anti-compression layer of synthetic Heatseeker™ eco insulation offers thermal protection on the underside of the bag. This version is lighter yet roomier than previous iterations.
