What our customers are saying
Customers say these leggings offer comfortable compression and leak protection for workouts. Many reviews mention the convenient pocket feature, though some wish for additional pockets. Common feedback includes praise for the supportive waistband that doesn't roll. However, reviews are mixed on sizing and fit consistency - while most find them true to size, some report they run smaller than expected or slip down during activity. Users appreciate the confidence these leggings provide during exercise. A few mention concerns about breathability and fabric feel.

    I wish I didn’t wait so long to order these! These make life so much easier and comfortable when you suffer from mild leaks. I’ll definitely order more.

    Smaller than the other styles

    Fits a bit smaller than the non leak proof version of this legging. But it's a great legging overall. Squatproof too.

    Do not stay up!

    As I’m reading all the reviews I’m wondering if they sent me a a defected or trial version. They feel nice on! However they do not stay up. They start slipping off me as I’m walking and I have to pull them up every five seconds. In contrast when I look at the images in the description I notice that there is an elastic band around the waist on the inside. Mine does not have that elastic band. Which could mean they fixed the issue and sent me the previous version.

    The best leggings!

    I've never really been one for leggings before, but as I'm starting to get into a more active lifestyle, I figured I'd try a pair from Knix. That was one of the best decisions I've ever made! I love that my leggings add a little compression and is leakproof, so I feel supported and secure. The fact that it has a deep pocket makes it even more of a 10/10!!
