    Dream Boxer

    I love these but all I can get is black or blue and I would like to get the other 3 colors, the 3 plaid ones.

    Bought this for my husband to wear after his surgery to remove the prostate. I felt that the selection of support underwear were not particularly attractive or comfortable looking so after consulting with knix staff decided to give them a try. He really likes them and finds them comfortable . I find them attractive ;). Would recommend. They are recommended for women but absolutely also work for men.

    Make sure to read the size chart

    These fit much bigger than other Knix leakproof products. I ordered my typical medium and had to exchange for a small, could probably size down twice. The waistband was baggy. All other Knix I wear a medium.

    Daughter loves the Dream Boxers!

    I bought a pair for my daughter and she absolutely loved it! She disappointed one of the patterns were unavailable in her size but I reassured her I would look on the site regularly until the other one she wants is in stock. Thank you!

    Not enough coverage at the back

    I was very excited to try this brand as I have another brand that I love but they don’t go up to heavy absorbency. These ones failed miserably in comparison. I’m not sure why the coverage doesn’t go onto the back of the underwear, this would make them so much better. I definitely leaked with this brand and I’ve tried more than one style (3 to be exact). Will not be buying again.

    Very comfy for wearing around the house. I sized up for more of an oversized fit.

    Comfy and Absorbent

    These sleep shorts are perfect. Not only comfortable and cute, but they do the job they’re supposed to! Super absorbing, full coverage and no leaks. So glad I made this purchase.
