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.
