As a core layer worn under Sitka Mountain Pants, these are good for around 20 degrees sitting and up to around 50 degrees walking. Else they’re not warm enough under 20 and or get too warm above 50. If it’s gonna be cold all day I’d recommend medium or heavy weight.

These are awesome. They help wick away moisture and dry pretty quick. I wear these into the stand and then once I cool down I replace them with a heavier layer or I'll just put the next layer on over them!

There is my favorite pair of long underwear bottoms. Warm, well made and a good fit! Sitka is a bit pricey but worth it in my opinion for what you get

My husband and sons all work outdoors all winter and have tried every kind of base layer imaginable. They say these are hands down the warmest, most comfortable pair they own. You wouldn't think they would be warm because they are so lightweight but they are. They are worn several days in a row and as soon as I get them washed they put them back on. They also have an odor guard technology that really works. They hold up wash after wash. I don't mind paying the higher price if they last and keep you warm. Sitka gear is great!
