[This review was collected as part of a promotion.] Keeps you warmer when outside. Natural and breathable fabric. I buy them every year for the winter.

These are so warm and comfortable! I bought a few of these and came back and my size was all gone. They sell so fast you'll be lucky to get one. If you see your size get as many as you can afford. This is the best deal in the entire USA on this item. I am very satisfied with this item. I love high end clothes and I'm fine with these.

Love these for any degree of cool - cold. I have neuropathy from chemo and these are the best at keeping be warm. Couldn't recommend them enough. I only wish I had bought more at Sam's before they left the store. At every other store they cost twice as much or more. Sad to see them go.

Awesome base layer. Keeps you warm and dry! Wish Sam's Club would bring them back.

Bought one for my husband & he loves it, so I'm back to order a few more.

Awesome keeps you comfortable working outside in the cold

I gave it a try, really. It was just far too itchy for me, despite washing and drying three times. I have other wool clothes that don't bother me like this shirt did.

At first they are great but with each washing they keep shrinking and shrinking.
