Why We Like The Mountain Hardwear Lamina -20F Sleeping Bag

As temperatures plummet toward the negatives and most people cozy up next to their fireplaces, we pack up our Mountain Hardwear Lamina -20F Sleeping Bag to enjoy the quiet serenity of the snow-laden woods. The durable bag is fully equipped to handle all the challenges of setting up a winter camp, with synthetic Temperlite insulation that maximizes thermal efficiency and maintains heat even while wet. Bidirectional bonded insulation eliminates cold spots and is targeted to provide warmth around our core and feet to minimize heat loss overnight. We can cinch down the hood to keep warm air trapped inside the bag, and the double draft collar blocks cold air so we can sleep comfortably in frigid conditions.


  • Durable cold-weather sleeping bag for winter expeditions
  • Temperlite insulation stays warm even in damp conditions
  • Lamina construction keeps insulation lofty and eliminates cold spots
  • Durable polyester and nylon materials protect the insulation
  • DWR treatment helps repel moisture as tent condensation builds
  • Mummy shape maximizes thermal efficiency for effortless warmth
  • Tailored hood can be cinched down to seal in heat
  • Draft collar blocks cold air from entering our bag while we rest

Chilly feet

NOT A -20 BAG. Left my feet and shoulders very cold on a night that didn’t get below 20F.
