I’ve only been able to put it to use a couple of times in moderate winter weather (20-30F), but it has been great! I have a light long sleeve top under it and BD Dawn Patrol Touring Pants and another lightweight top over them. Kept me quite comfortable on two climbs. With a shell top, I’d be good to 0F or a little below.
