My search is over
Size: Medium, Color: Black
Every few years I have to conduct an underwear search because my existing pairs are failing and the same make/model is no longer available. This year I tried several options until I found these. They are a good length, stopping at the upper thigh. They are comfortable and the elastic is tight enough to stay in place but not cut off my circulation.

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.
