Does is matter how good your outer shell is breath ability wise if your mid-layer doesn’t wick moisture that well? My upper body tends to sweat alot and I’m wondering if I should upgrade my shell or my mid-layer. I’ve been wearing UA cold gear compression shirt as my base layer, The North Face jacket for the outer shell (HyVent 2L shell) which has a 17K rating and a old TNF fleece jacket as my mid layer.
