Being a teen is tough enough as is, but it can be even more of a struggle during that time of the month. Even as an adult, your period can still have a way of throwing off your game or making you feel less confident than you usually are. Fortunately, Knix created Kt by Knix, which is a line of period-proof undies, loungewear, and swimwear specifically made for teens and tweens.

Their products are super cute and look just like the panties, leggings, or swimsuits you already buy for your teen, but with the added layers of protection to avoid any potentially embarrassing leaks. As you can imagine, that can go a long way in terms of your teen’s confidence. In fact, one parent raved, “My tween daughter loves her period underwear! She was really worried about having to wear pads or tampons and these were the best solution. Anxiety is down and confidence is up!” Another shopper wrote, “Long are the days of big uncomfortable pads. I was very happy to introduce these to my young daughter as she loves them. A must for night time.”

Best part? Kt by Knix is having a huge End of Year Sale where you can score rare discounts on nearly all their shopper-loved styles for up to 60% off. It’s a great opportunity to stock up ahead of the new year. We rounded up a few on-sale products you’ll definitely want to snag ASAP. Check those out below.
