I bought this for my husband along with the sleep shorts and he loves them both. The material provides moisture wicking, temperature regulation and they're extremely soft.

Terrific sleep shorts

These shorts are just great. Soft and comfy, and they move in bed when I turn over without getting stuck on the sheets. I like having the pockets and wear them as a lounge short as well as a sleep short.
