The Best, As Far As Thermal Underwear Goes...,
Verified Purchase(What's this?)
This review is from: Carhartt Men's Big & Tall Heavyweight Cotton Thermal Crewneck Top (Apparel)
Great product. Really nice, thick, heavy-quality material and it fits well.
Only one caveat: Not as warm as Under Armour base layers. (But not as expensive, either). I found some expedition weight UA knock-offs at an online discounter for $18 and they are much warmer than the Carhartt thermals tops, too. But it's kind of apples to oranges I guess. If you're averse to synthetics and insist on cotton, I think this product (the Carhartt) is as good as you're gonna get.
I'll probably just order the pant version of this product, and use the UA tops for a winning combination.
