They are lightweight and don't ride up.

Perfect fit underneath my clothes. Comfortable/warm.

My son loves these and wears them every day

Fit is slightly loose, but they help as a base layer.

Good quality. Husband loved them. Perfect fit. Needed for trip arrived just in time.

My husband and son love them. Keeps them warm!

Great quality and very comfortable

Got these for my husband cuz he works outside quite a bit. He says they make a big difference.

Received XL SIZE THOUGH THEY are ADVERTISED AS XXL, very uncomfortable

[This review was collected as part of a promotion.] Hard to believe that this base layer is so warm and so light at this price. I wound up getting anther pair!
