These Fortress base layers are amazingly soft and comfortable! They are far superior in comfort in our opinion to the military ecwcs layering system. Plus with Fortress you have less layers vs ecwcs. Also with Fortress you can get soaked wet and still get warm. However with ecwcs primaloft soaked wet...uh oh your in trouble. (same with goose down) We have not tested these yet in the cold, but we remember when we first tried on the ecwcs system before we tested it in the cold. (and the ecwcs works well in the cold) The fortress feels way better in temperature regulation thus far pre cold test vs the ecwcs pre cold test. I have every confidence Fortress will blow away ecwcs in the cold with less layers and more comfort. That’s why we bought the whole family not only one set each of these base pros, but 2 sets! Did I say they are comfortable oh my!

I received my Fortress BasePro Crew over a month ago and just now got to test it out for the first time on a deep powder snowmobile ride. I usually get cold quick, so I dressed warm and wore a smartwool hoody over the BasePro Crew. Shortly into the ride I had to take the hoody off. The BasePro crew, combined with my Goretex shell worked amazing. I was the most comfortable I’ve ever felt sledding. Sweat had no impact on feeling warm and comfy. I often change layers 2 to 3 times on every ride, not this time. I’m super happy with this purchase and will recommend it to all my friends.

I work out in the desert sometimes for 10-12 hours and I recently started wearing the Fortress Tops and bottoms when it was 39 degrees and I can tell you it was so much easier to concentrate on work and doing what I needed to accomplish while still dealing with the inclement weather. I highly recommend anyone working in a cold weather environment to wear Fortress gear!

This is an outstanding product,
