The Gregarius Winter Jacket reworks the classic soft shell around a 2-layer fabric at the front shoulder and upper sleeve, lined rather than bonded with a proprietary 3D mesh fleece insulation. That construction keeps the jacket at 300 grams in a men's medium while still managing moisture and holding warmth through a deep winter ride, at a weight that traditional soft shells can't match. What Our Gearhead(R) Experts Are Saying:"I've worn this from just above freezing into the high thirties without once wishing I'd grabbed something heavier, and the fabric still breathes enough that I'm not peeling it off two hours in. That's the difference between staying warm and starting to sweat inside a chilly jacket."
