Explore May 2010 Never Summer

This is a mummy masterpiece. It feels roomy for a mummy bag, yet it packs down relatively small. And it’s true to its warmth rating. We were comfortable at -15°C sleeping on snow thanks to the 600-fill down, the baffles around the neck and along the heavy-duty zipper, and the hood that cinches smoothly. The outer shell is made from Marmot’s Membrain Strata, a superlight, waterproof and breathable material that cuts weight and keeps condensation at bay. Paired with a liner or bivy sack, the Never Summer has the power to handle most winter-camping trips.
