    Super happy

    No leak, confortable, not too fit and not too big. The sizing chart was perfect for me. I'm 5'5'', around 280 lbs and 22 pant size.

    Not a fan

    Ordered for bladder leak protection and the padding isnt positioned forward enough for confidence wearing.

    Confidence

    These panties served their purpose to the max. They are comfortable and the leakproof aspect is wonderful.

    Does the job

    The underwear does what it promises. Way better than wearing a pad.

    The floating gusset is a mess

    The floating gusset in these underwear is not efficient or effective at all. It's like wearing a pad with no wings. It's never fully in alignment with the underwear itself and it easily misses blood or urine that soaks through the underwear instead. It's very bulky and very uncomfortable. Please go back to a fully sewn-in gusset!

    Seam at hip uncomfortable

    I really wanted to like these but the seam at the hip was bulky and uncomfortable.

    Comfortable undies

    I like the leakproof underwear. I always look for a high % of cotton in the fabric. Snug fit, good coverage to feel protected from leaks and well made.

    Really comfy, but…

    I wear leggings so there is a panty line when I wear these because they’re made a heavy cotton material. I live in Hawaïi so these panties are a little warm, too.
