keeps my thighs from chafing and my butt dry

I used to wear my partner's briefs or biker shorts to prevent chafing and sweat marks on seats but it limits me to wearing flowy dresses to hide the lines. It's nice to finally have something designed for the woman body that is smooth (no lines) and has no shapewear features. I went back and bought four more pairs so I can wear dresses all summer long.

Nice but too big

I ordered the thigh savers and they are really nice but I should have ordered a size down so a bit disappointing but that’s my fault nothing to do with the product. Knix products are amazing

Cute

I have ditched pads for this underwear! I love a good pair of KT by Knix underwear! This style feels more supportive to me than the sleepover shorts, but I still love those.

So comfy

Not only are these leakproof, they feel so smooth, you forget you’re wearing them. Don’t roll down. Does some shaping.
