Bought for a base layer
"Bought for a base layer while elk hunting in CO. Wore this as my base the entire 4 days of hunting/hiking/spike camping. Honestly it never came off those 96 hours. Very impressed with the ability to wear only this with a poly over and/or then layered all the way up to a "puffy" (synthetic down coat) in the 18 degree night hiking out of country. Impressed with the function, as well as holding up through the elements."
