Carhartt Force®

Keep your cool with sweat-wicking FastDry® technology.

All Carhartt Force® gear wicks sweat thanks to FastDry® technology. Force also either fights odors, releases stains with Stain Breaker® technology, or both.
Fast Dry technology has superior wicking action which makes perspiration a memory. The bottom line is that Force works harder, day in and day out, for hard-working men and women, at a price that doesn’t bring out complaints at the kitchen table.

Product is very warm, and very light feeling when wearing it. But it's very uncomfortable in the couch area.

Warm
I cannot believe how much it kept me warm. I am impressed with the overall fit and functionality. Does not feel like your regular tight fitting thermals. Loose enough to breath, but tight enough to keep you warm.

Warm but not really Heavy
It would be way better made with 80% wool and real thick for -25C to -40C!

I like the base force line of base layer thermals. The only reason I didn't give them a full 5 stars is because they do itch some. But they work.

My husband needed a new pair of long underwear for work, and he loves them. He definitely feels warm in them!

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