    Never sleep better

    Sleeping in Dream Boxer is very comfortable and makes me feel so safe that i don't need to worry about leaking, not to mention it's so cute as well!

    So pretty!

    These are so cute! Never thought I would feel pretty in a pair of period underwear.

    I had to return them for a smaller size however. I ordered Mediums in the high rise and bikini leakproof underwear and the medium in these was huge all over. Definitely size down!

    Comfy sleep shorts

    I could have sized up, but I’m between sizes so I’m not surprised. They’re just a bit tighter than I would like, but still comfortable. I feel secure and not worried about leaks!

    PLEASE PLEASE PLEASE RESTOCK

    Omg I love these. I haven’t bought period underwear in a while, but I desperately needed new ones and I finally did. I LOVE how these fit and they make me feel significantly less “ugh” during my cycle. I just tried my first pair of these on - got delivered yesterday - and I came right back to buy more but there are severely limited colors/patterns available in my size (medium) - there’s only 2! Please say you’ll restock in other colors/patterns in this style!

    From the reviews I’ve read, they look like everyone loves these & they work really well. These are Christmas gifts for my daughters, so I can’t say whether they work well or not.

    Lack of protection.

    Well. How is one supposed to trust that this is leak proof when the gusset is so small? Nothing in the front and barely much in the back. As a belly sleeper who bleeds at times in the front this was an awful purchase.

    And since it wasn’t a size issue but a product issue, I am out a lot of money because Knix only offers store credit. What am I supposed to buy when you don’t offer anything that actually covers me in a way that I need? Terrible company and terrible products and I won’t be buying again.
