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.

Warm and Comfortable for Everyday Wear

Size: XX-Large, Color: Light Grey

This thermal set is really comfortable and does a good job keeping you warm in colder weather. The fleece lining is soft and cozy without feeling too heavy, and it works well as a base layer under regular clothes. The fit is true to size with a nice amount of stretch, so it is easy to move around in and does not feel restrictive. It is also lightweight enough to wear throughout the day. The only reason for 4 stars instead of 5 is that it could be a little thicker for extremely cold temperatures, but it still works well for most everyday use. Overall, this is a solid and comfortable thermal set that is great for layering and staying warm. I would recommend it.
