Warm and comfy thermal wear
Size: Small, Color: Navy
They are very soft, don't ride up. Clothes do not stick to them like other thermals do. The fit is perfect. They are warm and comfy. The quality is good, too.

Perfect
Size: Large, Color: Navy
Oooooo these are so nice and soft and so warm! I am a nurse and work in an old hospital that is getting remodeled and there have been days we haven’t had heat and I have been very happy that I purchased these. My scrubs glide very nicely over these and don’t add any bulk. Definitely worth every penny! The fit is spot on and they wash up really well.
