This is my 5th order of this brand of men's underwear, and I have tried them all. The most expensive brands got loose and would tear at the seams after 8 months. Not these. They fit great, stay tight, hug the leg and always look new. I wash them on warm and dry them on low. I have had other bamboo-ish junk holders before, but these are by far the best. Do not pass these by. They fit great, look great, feel great, and keep my boys nice and cool, regardless of the temperature.
