The Millibar harnesses GORE-TEX INFINIUM™ WINDSTOPPER® technology to block wind, shed weather and stretch liberally — adeptly walking the ridgeline between protection and liberation with alpine style.

When ripping fast groomers or just ticking a bluebird powder day, our Millibar combines windproof performance with midmountain warmth. GORE-TEX INFINIUM™ WINDSTOPPER® blocks wind, sheds weather and stretches liberally, while underarm stretch-woven panels add range and core-cooling breathability. Shaped with a clean aesthetic and warmed with a brushed microgrid fleece backer, the ski hill style also features a fixed halo-adjust hood, four zippered pockets and low-profile stretch cuffs. An adjustable hem seals out the elements.
