Highly Recommend these as daily socks
Size: X-Large, Color: Black
I love these socks. I’ve been wearing for years. There was a batch I purchased about 2 years ago that all fell apart in the same seam location after 6 months but UA appears to have resolved. I highly recommend.

They're ok, miss the resistor 3.0
Size: Large, Color: Black
I bought these because Under Armour stopped making the resistor 3.0 socks. These are fine, but the resistors are better. This model is a little too form-fitting, and I have to make sure they're situated on my toes properly, otherwise they'll sit between my little toe and the next one.

Great quality.
Size: Large, Color: (001) Black / Black / White
Thickness and comfort are great. Quality is great and the same I would expect if I bought at the branded storefront.
