These BVD A-shirts are very nice undershirts or sleeping shirts. They wash nicely not shrinking to much and keep their shape after washing. The cut, thickness and fit is great, the shirts are stretchy and snug fitting, tho I buy a size larger because some shrink a bit over time and I like a little bit more room in them, snug but not tight fitting. I'm 6' and about 200 lbs and get the XL size and find they fit great in length and around the body.
