    Almost perfect

    If only Knix could blend those wonderful silky, no-shows with these insanely comfy cotton underwear! Then, they could do a line of sexy, comfy sweats, what do you think?

    My favourite underware

    These are my favourite underware. They’re so comfortable and the protection they give if you have any leakage with those sneezes is great!

    I have the bikini, boy short and these high waisters and love them all!

    Redesign is not an improvement

    All previous knix models that I purchased had sewen in liners. The most recent purchase had liners sewen in front and back, creating a sense of wearing a pad. Not what I look for in leak-free underwear.

    Genuinely stealth

    These are my favorite panties for everyday, though the price means I have to wait for sales to stock up; they look bulk and feel bulk free, unlike the other cotton machine wash and dryable period panties I have tried, and they still absorb light bladder leaks when I sneeze, or the surprise start of a period. That said they are still not completely perfect - I would love a version where the sides of the gusset were sewn to the sides of the cotton part, instead of just the front and back. and one with a slightly lower waist. And while I was excited to finally see some lighter colors to wear under lighter clothes, the black gusset shows through on the pink.

    Knix leakproof underwear is the best!

    I love these leakproof underwear! I was having problems with urine leaks and hated having to wear panty liners that weren't environmentally friendly. These solved the problem and gave me my dignity back. I only wear Knix now and am a happy customer for life!

    Leakproof cotton panties

    Very comfortable & effective in retaining moisture. They are made of quality cotton, which is hard to find these days.

    Loving them.

    I love my new Knix underwear as it is sooo comfortable and I no longer worry about little leaks! Goodbye panty liners. The material is soft and the waistband doesn’t roll. Easy to take care of too! Terrific products.
