Great cold weather addition

I have been wearing these almost daily this winter and they have not disappointed. They have traveled with me on glacier hikes, shoveling snow, outdoor work and daily wear around town. In temperatures from 30 degrees F to -17 degrees F they have warded off the cold. I usually wear these under a pair of cargo pants or under my uniform for work. They are comfortable and I forget that I am wearing them fairly often. Unlike other thermals I have worn these do a good job at adjusting to warmer temperatures when you get indoors out of the cold. They can still get toasty indoors, but less so than other brands I have tried. If you are working in -5 degrees F or lower you might want to look at a pair of firstlite’s thicker thermal offerings in my opinion. These have worked great for me and I have no regrets with my purchase. They fit comfortably and don’t tent to fall down through the day. They have also held up well through multiple trips through the washing machine. buy with confidence.

Lives up to the hype

I've worn these for a few weeks now and I have to say, I'm impressed. I put these to the test on a recent goose hunt and they kept me regulated surprisingly well. After carrying 3 blinds and 3 dozen decoys a fair distance I was sweating like a pig. When I finally got to hanging out in the blind I didn't get that cold bite that would normally happen. Instead, I stayed warm the entire time. After the hunt, and stripping the waders, I was yet again drenched in sweat with temps around 30 degrees. Legs stayed warm and dried super quick, unlike a polyester top I was wearing. No sweat smell! These are great!!

MensFuse Long John

Perfect base layer for Southern California bird hunting. It’s cold in the mornings, but warms up during the day. It’s ideal for those 35-70 degree days, plenty warm but doesn’t make you sweat when the temps go up. I’ll buy more for sure.
