I have quite a bit of BO merino.
I hunt in it... a lot.
During winter, I wear their bottoms almost daily. They get worn a lot and washed a lot.
Zero problems, zero holes.
I have some that is several years old and still perform like new.
Far exceeded my expectations.
I have never noticed it being rough or "scratchy" like an above post described.
I suppose men are made different nowadays as I see posts about "comfortable underwear", most comfortable t-shirts, jeans, packs, socks triggers, etc.
I never gave it consideration and have really only found one or two brands of T's that were similar to wearing a new canvas outfitter tent across my nipples.
