Russell Mens & Big Men's L3 Tech Grid Baselayer Performance Thermal Underwear Pant, Sizes M-5XL

from Michelle

Warmest thermal underwear around. Couldn't live without! So comfy and warm.

from Sean

This will be my second pair of these warm under pants. I use them at work under my jeans and can't work without them when it is cold out. They stop the air from blowing through the fabric. I still have the other pair from over two years ago. The reason I am buying g another is because I knelt do...

from chris

These things are my favorite and wished they'd put them back on the shelves again. Awesome fit, keeps me warm while I'm out in the snow fixing electric lines. I'm in 15-50 degree weather during the winter and they keep me warmer than any other brand I've tried. I just bought another 3 pair.

from Roger

True to size, love the fit and they are warm,did not shrink after washing and drying. I highly recommend them

from Beaubrandi

bought these thinking they would suffice as long underwear. their material is very thin, but they hold my bidy heat in, so im a happy camper. have always been pleased with Russell products
