Worth the buy!
Size: Medium, Color: Black
These socks wash well and have lasted us through the year without holes wearing in them. This is actually the 2nd pack we’ve purchased and will definitely buy more when we outgrow these.

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.
