This jacket is sick AF! Seriously, the best jacket ever. Polar tech alpha in the chest and back panels really keep you warm while being super breathable and no insulation on the sides and arms keeps you cool while deflecting wind at the same time.
I’m normally a greasy little sweat hog skinning up the hill if it’s over 20° but this thing regulates temp as if it were crafted by dark wizards using the olde magic.
FWIW, with a heavier base layer underneath, I summited Shasta in mid March with -25°f windchill at the top and never put on a heavier layer. Just an amazing piece of gear.
Just getting into backcountry skiing and this jacket hit the spot. Light, keeps in body warmth, breathes and protects form the wind. Great recommendation!
