The biggest question when it comes to period underwear is: does it actually work? The short answer is yes, when you use products from top-rated brands like Knix—which makes some of the best period underwear we’ve ever tested. We love Knix underwear and period-proof swimwear, and this sale is even more reason to smile. 

Among the items included in the sale are the Knix leakproof bikini underwear we loved. Usually selling for $22 each, you can save as much as $4.40 when you make a bundle purchase—they will ring up at $19.80 per pair when you buy three or more, $18.70 per pair for five or more and $17.60 per pair for seven or more. Offering medium absorbency, these underwear are ultra-comfortable and work well for light spotting days or when worn along with a tampon, according to our tester. Available in plenty of colors and in sizes ranging from XS up to XXXXL, they’re easily machine washable and are designed to absorb up to three teaspoons of liquid.

If thongs are more your style, go for the Knix leakproof thong, which would come down from $20 a pair to $18 each for 3 or 4 pairs, $17 each for five or six pairs and $16 each for seven or more pairs. We tested these ones, too, and appreciated that they stayed invisible under clothing. We’d recommend them for lighter period days, as a tampon backup or to absorb sweat and urine as needed. In the same size options as the bikini underwear and with 10 colors to choose from, the quick dry, anti-odor material is appreciated along with the ability to toss these in the washing machine. 

Knix period underwear offers that extra layer of protection, quite literally, that can make all the difference. Take advantage of this limited-time bundle deal to try the best-selling undies for yourself.
