Heavier than I thought in a good way
Was looking for a heavier weight base layer. Got these bc they were on sale. Def warm. Bought two, been cycling them out almost everyday for a couple weeks, including 4 ice fishing trips. Nice enough to wear as a reg long sleeve shirt. Not so stretchy. Solid, stiffer fabric. Def preferred compared to my old school long jon style.
