What wind shirt are you running? Does it also breath? Is it a crew neck or QZ? Im really interested in adding a wind shirt to my kit. I need to research this some more.first suggestion is to invest in a windshirt- by far the most used item of outdoor clothing I own- that's all four seasons
layered over just a light base layer can often get me into the mid 30's on the move, over a heavier base layer or fleece lower yet- it obviously deflects wind, but also does a good job with light precipitation AND is on the order of tenfold more breathable than any hardshell piece
if you need more insulation (on the move)- Patagonia's Nano Air light hoody is tough to beat
