    my husband was delighted

    I gave these to him for Christmas, and he was so pleased that I'm buying him another set for Valentine's Day. A great replacement for his ratty old sleepwear.

    Insanely comfy!

    Extremely comfortable and well made. Dry super quick on the hanger. I only wish there was an option of no plastic wrapping for the eco conscious. This is 2025, plastic packaging should be illegal.

    Awesome!

    As a woman I wanted longer shorts so I had to get the men’s and they fit great and are super stretchy. I wouldn’t wear them out of the house due to how thin they are but they’re super comfortable

    So soft and warm

    I've been trying to get my husband to invest in one of these for along time, I gave in and bought him one.

    He is now toasty and warm (he has hyperthyroidism) and looks lovely too!
