A nice bonus is the built-in protection from UV rays, making this set useful for outdoor use in winter sun.

The design includes thoughtful features like thumbholes and a tag-free label for added comfort throughout the day. The weight strikes a balance between warmth and avoiding bulk, so it can be worn alone or layered under outerwear. This set suits women who want a cozy, flexible thermal base layer for casual or active winter wear.

For those needing heavy-duty performance or advanced odor control, other options might be more suitable.
