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.

    Should have gotten more

    The cotton is very comfortable, and the level of protection is great against the coughing/sneezing leaks that apparently come with "a certain age". Would happily get more, and in lighter colours.

    Toronto Knix Underwear - Avoids Wet Marks On Clothes

    Helps adsorb perspiration from apron belly and keeps me calm while getting to a bathroom during sudden urinary urgency. Would appreciate more light colour choices to wear under summer clothes.
