Reviews Summary
Customers say these cotton leakproof underwear are exceptionally comfortable and effective for bladder leaks and period protection. Many reviews mention the soft cotton fabric feels breathable, especially in hot weather. Users appreciate the high-rise fit that stays in place without rolling down. Common feedback includes praise for the absorbent protection that eliminates the need for pads or liners. However, some note concerns about the floating gusset design shifting or bunching, with several preferring the previous sewn-in liner style. A few mention sizing inconsistencies and bulkiness issues. Overall, customers find these underwear comfortable for daily wear and reliable protection.

    Gives me confidence back

    I use mine for bladder leakage, mostly for when I’m not in my home. I find I’m so much more relaxed about not knowing where a washroom will be/if there will be one when I’m out. I used to stop in at almost every washroom I came across just in case… now I can relax and only go when I truly need to. I can go for long walks again and don’t have to “fearful” of sneezes or coughing. Truly such a great product.

    Love!

    I love this pair - they fit great and are very comfortable to wear. Sorry it’s a last call because I would get a few more pair in other colors if they were available.
