Great Mid-Weight Long Johns
These are heavy enough to keep me warm, but light-weight to fit under work pants.

Nice tight fit
I ordered the medium size bottoms, they are a perfect fit for my 5’6 165 lbs frame. They have kept me warm lately when the temperature dropped below 40 degrees, i was disappointed with the color, I ordered black, they look more like dark gray.

PERECT FIT FOR A TALL MAN
I bought these for my father because he’s always cold. We’ve had a hard time trying to find thermals that fit his long legs and arms and these worked out perfectly.

Not great
There is pilling after one wash and doubt it will help during cold weather because it’s not really helping during mild weather. Disappointed in the set as I thought I was getting at least good quality when spending over $100 on the set.

Keeps my husband super warm & dry!
My husband is a diesel mechanic and often gets called out to the roads to fix a broken machine and at times is called to work out in the field for the company he works for. On those really cold days the weather can be unbearable. He absolutely loves have a few sets of these thermals. I'm back again this season to buy a few more sets for Christmas for him among other items.

looks good and fits well
looks good and fits well. The only reason I gave them 4 stars and not 5 is because I think they cost a little to much.

Keep Cozy
As soon as you put these on you can feel the warmth. They keep you cozy will being outside in the winter. They are also comfortable because they are easy to bend and move in so you don't feel restricted even with another layer under everything.
