Built for swimming, absorbs 2 tampons worth of blood, perfect for pool and beach days. Hi. I’m the Swim. Teen Bikini, and I’m here to make swimming on your period a non-issue. I look and feel like a normal, great bikini bottom: soft, comfortable, and made to move. The difference? I quietly absorb period blood while swimming, so you can stay in the water without worrying about leaks, tampons, or timing bathroom breaks. How do I work? You slip me on just like regular swim bottoms and head to the pool, beach, or lake. While you swims, I’m doing the behind-the-scenes work — absorbing period blood on the inside while keeping outside water out. That means no baggy feeling, no visible strings, and no constant checking. For many teens, summer swimming can be stressful during their period. It often means leaving the pool early, skipping activities, or worrying the whole time about leaks or embarrassment. I’m designed to take that stress away, so you can swim confidently, stay present, and enjoy the moment like everyone else. The only decision left? Which bikini top to wear with me. (Good news: I go with all of them.) A few notes about our Period. Swimwear: It’s normal for the garment to fit snug when dry. It will relax and grow a bit when wet. Have more questions about Period.
