Le Skieur LW Anorak

Rated 5.0 out of 5
Based on 6 reviews


Gilles Sierro x TREW Ex Div.

Le Skieur Anorak is the product of a two-year collaboration with Swiss Mountain Guide, Gilles Sierro, and the TREW Experimental Division. The prompt was to reimagine an ultralight touring shell to Gilles’ specifications and effortless style. We can sum up Gilles' style with this mantra: make hard things look easy and have no wasted effort.

TREW Ex Div brought this mantra to life by creating a backcountry shell that is easy to move in and intuitive to use with your backcountry system. Every feature and detail is intended to help the wearer flow through the mountains with style.

The Fit

Designed with the minimalist in mind, this jacket has our slimmest and longest fit.


Our lightest and most breathable jacket, the Le Skieur Anorak is built specifically to keep that air flow game strong while moving fast up and down mountains.


With high breathability comes a loss in durability, so take a bit more care around trees + edges with this LW 3L kit.
