Very comfortable, right length
Size: Large, Color: Black,grey
This product arrived as described. I like the trunk length, not the boxer brief length. They are comfortable. Hold up well when worn and washed. I don't seem to sweat as much. These were ordered to replace ones ordered about 2-3 years ago due loss of weight, had to down size. The waist band doesn't roll as like other brands.

Nice briefs, worth the price
Size: Medium, Color: White
Briefs feel nice and I love the feel of cotton. Unfortunately they are missing a slot in the crotch that is usually present in these types of briefs.
Size is matching, soft to the touch.
