Eli ★★★★★

Took this bag on a multi-day winter traverse and the extra room compared to standard mummy bags made a huge difference for comfort. The -10°C rating held true through a surprisingly cold night, and the draft collar kept the warmth sealed in nicely.

Jason ★★★★★

Used this on a frosty -10°C night and the extra room compared to typical mummy bags made a real difference for comfort. The draft collar kept the cold out effectively and I slept warm through to morning.

Zoe ★★★★★

Took this on a winter mountaineering trip and the extra room compared to typical mummy bags made a huge difference for comfort. The -10 rating held up perfectly through a windy night near treeline, and I stayed warm without feeling restricted.
