All of our swimsuits have the same patented, 3-layer leakproof technology as our underwear plus an additional thin layer of waterproof material for extra protection. Here’s the breakdown.
First layer: Moisture-wicking, antimicrobial technology wicks away sweat and moisture while neutralizing odors to keep you fresh all day long.
Second layer: A super thin, highly-absorbent liner that holds the power of 3 tampons.
Third layer: A secure, liquid-resistant outer layer keeps leaks from happening.
Fourth layer: Another thin layer of waterproof material for extra protection.
KT Swimwear has a super discreet absorbent pad in the gusset liner that absorbs up to 3 tsps of blood, which equals about 3 tampons or pads.
Not always. When your flow is light, KT Swimwear can be worn alone without any additional period protection. On super heavy days, the swimwear works great as backup protection with a tampon or menstrual cup. Every period is different though, and we recommend doing whatever makes you feel most confident.
The layers in the gusset of the underwear work to trap and absorb blood. We want you to feel 100% confident in your KT Swimwear, so if it is a super heavy flow day, we suggest wearing a tampon or menstrual cup with your suit.
Just machine-wash cold and lay flat to dry. Do not bleach.
Definitely. KT Swimwear is seawater and chlorine resistant, and has 50+ SPF protection!
