Mountain Hardwear, Lamina Sleeping Bag: -20F Synthetic, Fiery Red, Reg/Right Zip

When winter settles in and temperatures plunge deep into the negatives, we rely on the Mountain Hardwear Lamina -20F Sleeping Bag to keep us warm through long alpine nights. Built for cold-weather expeditions, this rugged bag lets us venture into quiet, snow-covered forests and high mountain camps where dependable warmth is essential. Its efficient mummy design traps heat close to our body so we can rest comfortably even when frost settles outside the tent. Synthetic Temperlite insulation delivers reliable warmth that continues to perform even in damp conditions, making it a dependable option for extended winter trips. The Lamina construction bonds insulation in place to eliminate cold spots and concentrate warmth where we need it most—around the core and feet. A cinchable hood and dual draft collars seal in heat while blocking icy air from creeping inside the bag. Durable shell materials stand up to rough winter camps and repeated packing, while the DWR treatment helps resist moisture from condensation or snow. Whether we’re setting up basecamp deep in the mountains or enjoying a quiet night in the backcountry, the Lamina -20F Sleeping Bag keeps us protected when winter is at its coldest.
