I got these for my husband and he liked the idea of them a lot except for the waistband being much too tight. He wore them for a full day and complained about them actually hurting.

*I got him a Medium as he is always a M being about 6' and 160lbs.
*He lost 20lbs living abroad and even with this recent weight loss the waistband is still too tight at a size M. I slipped my fingers between the band and his body and I agree, they are painfully, suffocatingly tight. Beyond tighter than any of his other underwear.
*There's no way a large would fit in the legs/groin the right way because these fit perfectly on him despite the band.

What a shame! A total waste of money.
