Its lightweight, breathable structure retains warmth and air, but with plenty of options to ventilate it works really well when you’re working hard.

Mammut’s lightest midlayer is the perfect solution for ambitious mountain athletes or anyone who prizes the highest possible performance at the lowest possible weight.
