Importance of Mid-layer in overall breathability?
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.
Should I upgrade my outer shell to a Gore-Tex jacket or upgrade to a higher performance mid-layer?
I'm wondering what would help more as far as keeping me dry from sweating.
