Fantastic socks for USAF or other military uniform. I'm in uniform all day and these socks keep my feet from smelling and keeps them comfortable all day! Great quality as well!

Nice Quality Socks
Color: Coyote Brown, 3 Pack, Size: Large, Color: Coyote Brown, 3 Pack, Size: Large
Hate shopping for clothes online, even for socks. Looked at lots of different brands and settled on these due to their customer reviews which seemed positive. I ordered 2 of the 3 packs of the coyote brown in the large size. The color is pretty accurate to the advertisement. You can see my picture of the new sock unrolled straight out of the box alongside a tape measure that shows the length. The socks seem like they are very good quality. The aren't thin or see through like some of the cheaper options I considered. To me the are similar in thickness to a name brand white tube sock like Hanes or Fruit of the Loom. The large size is 18 1/2 inches long in it's natural shape and easily stretches over the calf but below the knee. I wanted to lighten the color to more closely match my work pants and tried washing them 5 times with bleach mixed in the washer. They held their color, and elasticity even with the bleach, so I didn't get the color change I was hoping for but goes to show that under normal washing (without bleach) the color won't likely fade anytime soon. The have great stretch and elasticity and stay up above the calf all day without sliding down. Definitely ordering these again when needed.

Good replacement for GI socks
Color: Green, 4 Pack, Size: Medium
I ordered these for my son, he’s in the military and the socks they issued him were all getting holes worn in the top of the toe area from his work boots. So I ordered him some of these to supplement his normal ones. He said they’re pretty comfortable, we’ll see how they hold up after he wears them for awhile. But initially I’d say they’re a good buy. Points for the affordability.
