Shop The Collection

The Best-Selling Boyshorts, Bikinis, & Briefs

Period undies are what Kt by Knix is super-famous for, and anyone who menstruates can benefit from these absorbent underwear. You can shop by absorbency level (light to super) or by style, with options that include a bikini-style bottom, a boyshort, boxer briefs, and a high-rise brief. The website makes it easy to figure out what sort of coverage you’ll get, breaking it down by approximately how many tampons’ worth of blood each piece of underwear holds — with some pairs absorbing as much as 8 tampons or 12 pads-worth of blood.

Some styles are constructed from a buttery-soft cotton and modal fabric blend, but there’s also the brand’s signature leakproof design made with nylon if that feels more secure for you. You’ll even find seamless versions that disappear under leggings and shorts.

The One-And-Done Period Kit

Kt by Knix’s best-selling period kits are an easy and affordable way to bundle your favorites. You’ll find a variety of styles and absorbencies, and an overnight kit featuring their most absorbent products so you can sleep stress-free. The Everyday Leakproof kit is a great place to start: It comes with seven pairs of period underwear so you’re set for your whole cycle, plus a reusable pouch. Choose from their bikini, boy short, or high-rise styles; whichever you land on, each pair promises to absorb multiple tampons’ worth of blood while preventing leaks, nixing odor, and wicking moisture. They’ve even got a Vacation-Ready kit that — along with some of its classic period underwear — includes a period swimsuit. (Because, NBD, they make those, too. But more on that below.)

The Leakproof Swimwear For Even Your Heaviest Days

Speaking of swimsuits, you can choose from one-pieces or bikini bottoms (plus the matching tops) and even filter your selections by bum coverage. Just like shopping for their underwear and period kits, each swimsuit clearly lists its absorbency. Whether you like a cheeky bikini or a full-coverage situation, there are plenty of cool colors and prints to choose from, in designs you’d want to wear even if you weren’t on your period, and these swimsuits have the added benefit of layers designed to trap blood and keep water out. Every suit features UPF 50+ sun protection and is built to resist both saltwater and chlorine — you’ll even find dedicated competition swimsuits designed by a former Canadian Olympic apparel designer that reduce drag, because your cycle shouldn’t get in the way of setting your next PB.

The Absorbent Activewear For The Gym & Beyond

For folks who stay on dry land, Knix has even expanded their design horizons to include activewear — so if you’re a gym, running, or dance baddie, you can find performance pieces that can handle your workout and offer period protection. Choose from a pair of classic pair of leggings, on-trend biker shorts, a leotard that can double as a bodysuit — even an essential pair of dance tights that are also great to layer under skirts or dresses. All of Kt by Knix’s activewear features layered gussets that can absorb multiple pads’ worth of blood and prevent leaks, with four-way stretch performance fabric that wicks away sweat.

In addition to kits and discounts for bundling up, refer a friend and you’ll both win big at checkout with 20% off. It might be difficult to decide between all of the cool and effective products, but it’s clear that period protection has never been easier.
