The REI Co-op Down Time 25 Men's pairs 600-fill-power down with a relaxed mummy cut rather than a snug performance taper, prioritizing room to move over minimal weight. At 1106 g with 471 g of fill, it's rated to a -4°C (25°F) limit and a 2°C comfort figure, positioning it as a three-season bag for spring, summer, and fall.
An insulated draft collar and full draft tube along the zipper stop the convective heat loss a full-length zipper otherwise invites, and a fitted, contoured hood adds warmth around the head without a separate balaclava. The 30D shell carries a DWR finish, and it's bluesign-approved for manufacturing. Both a stuff sack and a separate storage sack are included, useful since down bags should be stored loose to protect loft.
There's no two-way zipper for footbox venting and no option to zip two bags together, so it's a straightforward solo bag rather than a couples design. Sized for sleepers up to 182 cm, it suits adult hikers wanting a comfortable, room-forgiving down bag rather than the lightest possible option.
