Tried and True
Marmot Col MemBrain
Nothing makes you appreciate a really warm bag like a really cold night. Our testers’ first experience with Marmot’s down bags and their exceptional performance—thanks to great loft, meticulous construction, efficient shape, and smart details like stiffened draft tubes that don’t snag—was in 1979, when testers used the 5°F Gopher on frigid nights in New York’s Catskills. The same category-leading features continue to make Marmot’s bags—like the -20°F Col MemBrain (pictured) and the 15°F Helium MemBrain—best of class. After hitting several of Colorado’s Fourteeners with the Col, our current testers say that the waterproof/breathable MemBrain shell fabric keeps moisture at bay, yet still allows the bag to breathe so well that the 20-below bag stays comfortable to 20 above. $619; 4 lbs. 4 oz.; marmot.com.
