We tested nearly 50 sleeping bags to find these top choices. To winnow the field, our crew risked their zzzzs from the arctic cold of Alaska’s glaciers to month-long treks in China and Nepal. No matter what type of bag you need, we found the best in class.
Mountain Hardwear Phantom 15
“It’s like sleeping in a superheated cloud,” said one tester, describing why this bag was a unanimous favorite for all-purpose performance. Ultralight materials–800-fill down and a 15-denier, DWR- treated nylon shell–make the warmth-to-weight astounding, and it’s still plenty durable and resistant to condensation. The double-yoked, cinchable draft collar prevents cold air from jetting into the bag when you roll over. A zippered pocket at collarbone level keeps an alarm within earshot. And the shape is efficient, not constricting, with zero cold spots. Bonus: The shell fabric is more breathable than with previous versions, eliminating clamminess. One gripe: The zipper sticks where it curves around from shoulder to cheek. Reader Service #101
