Fit great
Size: Large, Color: (100) White / White / Halo Gray
Been a couple of months and they seem to be holding up nicely. Real picky about fit of socks and these fit well. They are very thin but very comfortable.

Always a win
Size: Large, Color: (001) Black / Black / Castlerock
Under armor is always a win! Comfortable, no peeling, true to size, no squeezing around the arch of foot & affordable.

Fit well and stay up
Size: Large, Color: (299) City Khaki / City Khaki / White
They're a little thin, so good mainly for warmer months. But they fit very well and I've not experienced any slippage
