Love these socks!
Fit Type: Classic Fit, Color: Black, Size: Large
They are a little on the thin side, but that is how I like them. Thin, comfortable, breathable, but still sturdy. They work great for me and I have bought them several times for me and my kids over the years.

Thin
Fit Type: Classic Fit, Color: Gray Assorted, Size: Medium
I bought these thinking they would be slightly thicker material. They are thin but don't make my feet sweat working outside in the heat while wearing them during my work shift. They are comfortable and stay in place so I don't have to keep fishing for them inside my shoe to move them up a bit.
The one thing I wish they had was the support band in the middle of the foot.

Super comfortable
Fit Type: Classic Fit, Color: Black, Size: Large
Love these socks. They are very soft fabric but also heavy so they are very durable. And the price is far cheaper than any of my local stores.
