Top-notch sleep shorts

I bought these for my husband. He says they are every bit as fantastic as the sleep shirts.

So comfortable and luxurious.

This review reflects his stats, not mine. ;o)

The shirts really do keep me cool at night.They stay color fast and didn’t shrink after a couple of washes.

I intend to get more. Worth the money! Great product.
