REI Co-op Down Time 25°F

After a day hiking among the clouds, you deserve a sleep system just as fluffy: The Down Time is the loftiest bag we tested this year. Though it contains midgrade 600-fill hydrophobic down, the overstuffed baffles are taller than those in other bags we used—giving each one extra volume—and are stitched in a pattern that creates larger baffles at the top of the bag and narrower baffles near the feet. The result is an even distribution of feathers from head to toe. A down neck collar (much larger than other bags tested) tucks in around sleepers’ chins, adding comfort to this mummy. Synthetic insulation in the footbox complements the down and kept our feet dry and warm even when we rubbed against a damp tent wall while camping in Colorado’s Indian Peaks Wilderness.
