Stache UL 25LStripped back summit pack, built to be carried as a second pack and unleashed for summit pushes, or used for acclimatization missions from basecamp.

But it still offers a full alpine pack feature set making it far more capable on technical objectives than typical lightweight summit packs. Burly uHMWPE fabric
