Men's Ortler Metawool 60 Rev Jacket 26/27

The Ortler Metawool 60 Rev Jacket is a lightweight, packable insulated jacket with a reversible design: one side for going up, the other for riding down. It is filled with 60 g/m² of Metawool:T, a natural insulation of 40% Tencel lyocell, 40% merino wool and 20% polylactide, under polyamide shells, one of them 100% recycled. It weighs 305 g.

On the climb you wear the Tencel side out to manage moisture, then flip it at the top so the merino side keeps you warm on the descent. The trade-off is that 60 g/m² is a light fill, so on a bitter day it works best as a layer under a shell like the Ortler Gore-Tex Jacket rather than on its own.

Ortovox rates it top marks for ski touring and strong for mountaineering. It is for touring skiers who want one smart insulating piece that handles sweat on the way up and warmth on the way down, without carrying two layers.

Regular fit with elastic cuffs and an elastic waist. The going-up side has two front pockets and the riding-down side has a backpack-compatible chest pocket.

We think it is one of the cleverest touring layers out there, and it makes every transition at the top a little quicker and a lot warmer.
