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.

“In the mid-90s, when I first tested this 20°F synthetic bag in New York’s Catskills, I was impressed by its warmth (the temperature rating is conservative), its durability (I carelessly bivied among rocks and roots), and its killer price ($159). Since then, several aspects of the Cat’s Meow have been elevated: It’s now insulated with Climashield Prism, which is warmer, lighter (by two ounces), and less bulky than the old fill, and the hood has been retooled for a better fit. But the price on this inflation-buster has miraculously stayed the same (since 1993!). $159; 2 lbs. 10 oz. (reg.); thenorthface.com.

Going to extremes: During this 1992 sleeping pad test, our tester hacked out an ice ledge nearly 18,000 feet up a Bolivian mountain—and hit snooze.

Field Notes
“When the foot end of your sleeping bag rubs up against a condensation-ridden tent wall, the result is wet, cold feet, something I couldn’t afford on an already cold, wet staff trip along the Olympic Coast in 1997. That’s when I learned this technique: To protect my sack, I either wrap the foot end of my bag in my rainshell, or I stick it inside my pack or a spare garbage bag.” —Thom Hogan, Executive Editor, 1997-2000

1. Size matters. Climb in different models and check wiggle room. A superefficient mummy cut is no use if you can’t sleep.
2. Go long. For cold-weather bags, get the long size. The extra space at the foot is a great place to keep water, batteries, and electronics from freezing.
3. Dress right. When you wear excess layers to bed in a trim-fitting mummy bag, the insulation compresses so the bag can’t keep you warm. But if your bag is roomy, layer up so your clothes take up the dead air space.
