"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."
"I love it so much I bought two! Warm, Comfortable and useful in just about every environment and situation."
"My favorite base layer for years. To bad simms not selling anymore. This bad news for me"
"We are having a big winter in western New York. My biggest steelhead creek, which generally runs 250 to 400 CFS, is even pretty iced over. I've been wearing my light weight base layer cross country skiing. The top is silky comfortable and kept me dry when heating up on my climbs skiing. The top runs small. Had to reorder a size up. Happy now."
"This is a very soft and comfortable long sleeve shirt— l sometimes use it as the first shirt I put on when layering in cold weather on a guided fishing trip while running on the water."
"M’s lightweight base layer keeps you very warm when used with a polar fleece and a rain jacket it’s very comfortable wicks perfectly on those cold rainy days when you are in it all day."
"This is what I wear. Core warmer"
"Good quality not heavy won’t restrict movement"
"Hard telling I haven’t worn them yet but soon."
"Awesome base layer with the right blend of materials"
