Overview
A broad-shouldered backpacker gets a goose down mummy bag cut roomier for larger sleepers, wrapped in a thin nylon ripstop shell. Continuous baffles let the down be moved around to suit the night.
Room to move without much weight is why this bag earns a look, especially for larger sleepers who feel squeezed in narrow mummies. Its warmth suits summer trips, and the right side zip and fixed length limit who can use it.
Who it's for
Summer bikepackers and backpackers with wide shoulders get space and low weight in one bag. Cold-weather campers and tall sleepers need a warmer or longer model.
Pros and cons
- Very low total weight
- Roomy shoulder girth
- Continuous baffles let you shift down
- Packs small in its stuff sack
- Summer rating only
- Length limits taller sleepers
- Right zip only in this version
- Water resistance not listed
Performance notes
Warmth comes from how much loft the goose down holds, and continuous baffles let you move fill toward the colder side of the bag. The extra girth adds air space to heat, so the warmth rating suits summer nights rather than cold ones.
