Great base layer
Like all origin projects well-designed. Do a great job of what they are bought for I plan to have them a while. Great for riding the bike in cool weather!

Base layer
Can’t bring myself to call it leggings, sounds little feminine. They’re super comfortable, & positive they’ll work out great keeping me warm on jobsite or in treestand
Best if all made in USA

super comfy baselayer
Little more substantial than some other super thin wool long johns, but not too thick. Really regulates temps and moisture well, great for the cold winter.
