The system enables you to stay comfortable, concealed and in the field longer through the worst of weather. Product Care.

  • Warm!
Size: Medium Color: Pyrite
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! ... show more

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
