Extremely Comfortable & Stretchy!
Size: Medium, Color: Black/Deep Grey/Grey/Deep Blue
These underwear fit great, are nice and breathable (which is great since I work outside here on the south with plenty of summer days over 90+ degrees) They are super stretchy & soft and seem like really nice quality. Wash them on cold and you won't have any shrinking issues. I've had these for a few months now and after many washes, they still retain their stretchy and soft feel.

Poor length & crotch fit.
Size: Medium, Color: Black
Poor support in the crotch area. Waist fits well. Legs too short & ride up. Expected fit to be as good as the Briefs design, which are a great fit. Do not want to chance buying a size down, not expected to be any better. Will buy another brand.
