Rothco ECWCS Gen III Mid-Weight Underwear Top & Bottom Set (Level II) Tactical Grid Fleece Thermals

I have the extrema cold military poly pro. Those are great until you really have to expend lots of heat generating activity. Too hot on the coldest nights. These are not that, they are perfect for working hard in the cold weather. They dry fast and after several days of working in the cold with these as my base layer they didn't smell! They do run big. I ordered both size large (normal for me) and then a medium. The medium is perfect for me, I'm 5'10" 190lbs. I'll buy more.

The best thermal underwear I have ever used. Not perfect but very warm. Flaws are minor stitching errors easily trimmed and a zipper that is a little sticky but functional. The extremely good performance in cold weather is far beyond typical thermals.

Wonderful stuff and great seller. I ordered a pair of Medium for myself and a Large for my buddy. I am convinced I could wear these and nothing else in 40 degree weather and keep warm. I had to take them off in the middle of the night when they arrived as I had it a normal 70 degrees inside. Very comfortable, light weight material.

The person loved this gift and couldn’t wait to try them

According to size chart 2x and it was to big sent back got xL its to big but just keeping nice and worm but zipper at the neck is hard to zip

Very warm and comfortable, make sure you order a size down from what you normally wear.

Wonderful product.
