      I love it

      Customer service was amazing and fast to respond when i had a deficiency. I work in the mountains and this base layer kept me warm in about 40 degree temperatures and raining... HIGHLY RECOMMENDED.

      Excellent Product and Excellent Service

      Because my wife is always cold, we visited the Fortress Clothing Factory in Mt. Pleasant, Utah, to see if they had any seconds that could help. We did this because we had done the same thing several years ago and were pleased with our purchases, but now wanted more. We found what we came for but ended up purchasing several non-seconds to provide us with more warmth. The build quality is great, which meant there wasn't a lot of seconds to select from, but we are happy with what we purchased, setting them aside until next winter.
