My daughters favorite brand

Bought these for my daughter for the Corps of Cadets at VT. we
Purposefully bought her 4 brands to try. Fox River needed up being her favorite. Highly recommend Fox River socks. The right thickness, material makeup, and comfort. She’s a happy new cadet and it’s the start to her military future wearing boots for her uniform. Timely service as well when I ordered last minute and requested they be expedited for my daughter to receive for her packing list in time. Thank you!!

Good socks

These are more of a medium thickness I would say. They are soft & don't bunch up. Great at absorbing sweat. Best socks I have ever worn. They are holding up to time pretty well too. I have some that are 3 years old and they still fit tight.

Good quality

I've been using these Copper Guardian Pro Medium Weight socks for tennis for about 10 months now. I have a total of 7 pairs. So far, they are not showing any wear. Good padding under the foot. The Large size fits my size 11D feet well. Not too tight or too loose.

David Andrews

Love these socks. My wife bought three pair to try. Loved them that much we bought another three pair. So comfortable, they fit like a glove. Love the added cushion as well as copper compression. Definitely recommend especially if you are a runner.

Flexfit Face Mask - I bought 2 then 5 more!

Pros: Comfortable, fit well without constant adjusting, breathing is easy, my glasses don't fog up! Put on & take off & put on again is easy & no ear loops to deal with. Cons: for larger head sizes, fit can be too tight. Fashionable? not. Wash carefully, colors bleed. Effective? Hope so!
