I’m not normally a long john kind of guy because trudging through thick cover tends to produce enough body heat that shedding layers is more likely the norm. But last year hunting late season we got caught in a Midwest blizzard with winds cutting at ridiculous speeds and ambient temps in the teens. That’s when I broke out the Under Armour Base 4.0 and it made me a believer ($80 crew/ $80 legs). I felt like Spiderman when I stretched into this base layer. It hugs the body while still putting a cushion of air next to the skin. With windchills reaching deep negatives and freezing rain coming in sideways the hunt continued…. until I could no longer feel my face. Hoping UA Base 4.0 for the face comes out this year.
