3.8

Knix earns largely positive reviews for effective, comfortable leakproof underwear that reduces leaks, odor, and visible lines, but reviews also flag inconsistent sizing and breathability. Reviews of Knix note standout pieces like the Dream Short, high‑waisted styles, and leakproof seamless briefs, while weaknesses include bras lacking support for DD+ or petite fits, some bulk in boyshorts, limited absorbent coverage placement, and occasional durability issues like liners peeling.

    I have only been wearing these period underwear for 3hours and they bleed through them. These suck and what is said is totally a lie on the box.

    I have been wearing Knix for 5+ years now. For both period and non-period/sweat/athletic day-to-day, I feel like Knix just makes me feel at ease. The only drawback is sometimes the waist elastic is a little tight, so sizing up makes it more comfy in my opinion!

    Such a fan of Knix bras! These bras are wireless, which is sooo good for your overall breast health and it makes them super light and comfortable to wear. Holds up the girls really well, with excellent supporting straps that are adjustable on some styles! Feels like I have nothing on throughout the day when I wear these!

    I love these panties. I have both regular and period ones. I don’t love the boy short period panties because they’re a little bulky. I prefer the Thinx version. Still, all around, great underwear that is really comfortable. Was not impressed with their leggings.

    Feedback

    Less bulky boyshort period panties and better, higher quality leggings.
