If you want warmth without synthetic fibers, these 100% cotton heavyweight men's thermals are just the ticket. They are the heaviest, warmest cotton thermal long underwear we could find, and are very comfortable to wear.
Once you hold these thermals in your hand, you won’t confuse them with cheap thermals from the discount mart so thin you can practically see through them – these are expedition weight and are rated for very cold temperatures.
This listing is for the SHIRT. Pants sold separately. Heavy raschel knit to trap and retain body heat. Designed for minimal shrinkage. Look for our matching thermal bottoms.
