The Atomic Treeline Microfleece with Thermagrid is an essential extra layer that matches the rest of the Treeline range, and is designed to be worn under your ski jacket.
A midlayer that fits perfectly with the rest of the Treeline collection.
Thermagrid is a stretchy, breathable fabric. Thanks to a special antimicrobial treatment it keeps you feeling fresh as well as warm. And because it’s thin and almost unbelievably lightweight, you’ll hardly know you’re wearing it.
