  • Stretch Mesh, Ventilated Construction: Soft, stretch mesh at the rear of the lower legs provides a comfortable fit for riders with various calf sizes, while the open knee construction behind the knee helps to prevent heat build-up while maximizes ventilation.
  • Extended Coverage: Extra side padding for extended coverage.

Repurchased many times. My husband's "everything" socks!
Size: X-Large, Color: White/Graphite (6-pairs)
My husband always asks for a new pack of these UA socks every birthday and Christmas. He wears them with all types of shoes and for everything he does: daily work, weekend casual, and athletics. They're thick, super soft, and durable, but yet still breathable--even in the heat of summer. It takes months and months of constant wear and washings before they develop holes in the heel. Great socks!

Great socks
Size: X-Large, Color: White/Graphite (6-pairs)
I really like these socks. Feel good, long lasting, high quality. Fortunately they are not as high at the ankle as they look in the picture.

Very Nice Athletic Socks - Fit as expected.
Size: X-Large, Color: Black/Graphite (6-pairs)
So far so good. I purchased the XL size and they fit well for my size 14 feet. They seem to have held up well in the 7 days I have been wearing them - 2 washes so far. Only time will tell if they last. I do know if you walk around the house in your socks they will develop holes on the bottom much faster than if you just wear them in shoes.

Favorite socks
Size: X-Large, Color: Black/Graphite (6-pairs)
Great quality, very comfortable and soft. Have a decent thickness to them without making your feet hot and aren't too tight around the ankles
