Thank you for your product! My son did 2 tours in Afghanistan as a Marine. I got him several pairs of socks when he did his first one and wore them through both. He has been out of the Corp for 2 years and is still wearing those socks and asked if I could get him some more : ) It's my pleasure to order again. They are wonderful! Thank you so much for keeping his feet comfortable while he was putting his life on the line!

I recieved my order a few days ago and wore the socks yesterday on a 16 hour shift. Very comfortable and I'm glad I found your company.

You really know how bad you want to fill a tag when you forget your boots, and get wet to the ankle. Feet weren't toasty warm today but I didnt tap out. Love these socks Wool Beast for the win at 18 degrees!

Hey team, Hope everyone is healthy and well. I have a few pairs of your desert socks that were sent to me in 2007 when I was deployed to Iraq (USMC). I still have these things 15 years later and they have as comfortable and solid as ever. Just Message want to thank you for producing some high-guality products and appreciate thework! I live in France now, but always supporting local American companies. Stay frosty, Josh

Not sure who reads these things.....but, I saw your brand while looking for some socks online and thought I would comment.Back in 2009 I was a newly commissioned Marine Corps 2ndLt at NC State University awaiting my orders to my next duty station. I received a phone call one day from a father inquiring about our NROTC program. We chatted for a bit and he mentioned this sock company and offered to send us a few samples. Being in the military and an avid runner...socks are a big deal. Long story short..... we received the package, I passed them out and kept a pair of running socks for myself. 12 years later I still have this pair of running socks... Im sure they have 1000 miles on them!! Great product!
