The Blue Ice Stache UL 25L is Blue Ice's lightest alpine pack, built for summit pushes. It is designed to be carried as a second pack and brought out once basecamp is behind you, stripping back to a featherweight 240g while still offering a genuinely technical feature set.

It shares its burly UHMWPE body fabric with the bigger Stache packs, so class-leading durability comes with the low weight, and it carries two technical tools securely. A removable waist belt, stretch side pocket and drawcord closure keep things simple, and it is hydration bladder and helmet compatible. Choose it when the summit day needs a real climbing pack that weighs almost nothing in the bottom of your expedition bag.
