Reviews Summary
Customers say these leakproof underwear are exceptionally comfortable and soft, feeling like regular underwear without bulk. They praise the excellent fit and reliable protection for periods and bladder leaks. Many appreciate the high-rise coverage and smooth, no-show design under clothing. Users frequently mention the durability, with pairs lasting years through regular washing. The stretchy, breathable fabric stays in place throughout the day. While most find them true to size, some recommend sizing down for a snugger fit. A few note concerns about recent design changes making them bulkier, and some mention limited color options for heavy protection styles.

    No other underwear ever again!

    Once I found Knix, I never looked at other companies.

    The leak proof panties work beautifully. No more worries.

    They are undetectable, feel comfortable and look so good!

    Excellent

    I have worn these for years now and would recommend to anyone that needs protection from minor leaks. Very comfortable, stay in place, no panty lines, great colour choices. Also quite reasonably priced especially on a sale.
