My kids laughed at me when I told them I used to wear "long johns" under my jeans growing, so stay warm. But this is the type of material these are made of. Perfect for fall. When I was packaging them, I noticed a hole on the seam of the back pocket. 3 ways to solve, one, stitch it, two, wear black underwear, or three, use them as a layer or wear a long sweater. Priced accordingly for this, thanks!
