Few things make me as happy as brands that create clothing and underwear designed specifically to make life easier (and stylish) for people on their periods. Kt by Knix is the newest of those uterus-friendly brands on my radar. With summer on the horizon, the timing couldn’t be better — its specialty is swimwear, making an active pool- or beachside life while on your period fun, comfy, and most of all, possible. But the swimsuits in Kt by Knix’s newest line, Break Free, are so cute you’ll want to wear them even when you’re not on your period.

You may already be familiar with Knix, which is known for its period underwear; think of Kt as Knix’s little sister. Like Knix, Kt by Knix is committed to making period products as accessible as possible. The new Break Free line includes both one- and two-piece swimsuits, all of which can hold up to three tampons or pads worth of blood thanks to their targeted, triple-layer design: A super-soft bottom layer; an ultra-absorbent liner middle layer; and a chlorine- and seawater-resistant top layer that traps in blood, repels water, and has UPF 50+ sun protection.

Note that Kt by Knix was designed with teens in mind, but people with periods of all ages can take advantage of these cute suits. If you are past your teen years, be sure to refer to the brand’s size chart, which shows how each of their sizes translates to adult pant sizes. (Kt by Knix’s size range extends from XXS to XXL, but according to their size chart, only sizes S and up can convert to adult sizes, ranging from 00-22.)

Shop Period-Friendly Swimsuits

Whether you like a full-coverage boy short or a cheeky bikini cut, you can enjoy period protection in style — and you’ll benefit from that absorbent, triple-layer design that ensures you can swim, float, or lounge securely without the need for an extra tampon or pad.
