Eco-friendly warmth for outdoor sleep

The Genesis +30° Mummy Sleeping Bag from ALPS Mountaineering blends efficiency with responsible design. The exterior is made from 100% recycled polyester ripstop, and the lining is also recycled polyester, crafted to reduce waste without sacrificing comfort. The two-layer construction uses Recycled TechLoft Micro Insulation, delivering dependable warmth while keeping the overall weight approachable.
