Each pair has a built-in liner that absorbs period blood. Kt Period Underwear is categorized by light, moderate, heavy and ultra flows so you can find the right pair for your teen’s needs.

Ultra Absorbency

Absorbs the equivalent of 7-11 super tampons. Our longest front-to-back liner, designed for their heaviest flow days and overnight protection.

Heavy Absorbency

Absorbs about the same as 4-7 super tampons. Perfect for overnight protection or your teens heaviest days when changing into a fresh pair might not be convenient.

Moderate Absorbency

Absorbs about 2.5 super tampons' worth of blood. Ideal for medium period days, discharge and sweat.

Light Absorbency

Absorbs about the same as about 1 regular tampon worth of blood, sweat or discharge. Ideal for lightest period days, spotting, sweat and discharge.

Our period swim bottoms have a triple-layer gusset that absorbs your flow and locks in leaks, in and out of the water. And when you throw them in the wash with detergent, everything releases through the top layer so your swimwear comes out fresh and clean. Your other clothes will be totally fine too, we promise.

Here's how the three layers break down:

Layer 1 is a silky-smooth top layer that sits right against the skin.
Layer 2 is a super absorbent middle layer built with our leakproof tech that holds up to 1–3 tampons worth of blood.
Layer 3 is a waterproof outer layer that prevents any leaks from showing through.

It's easy, we promise. Give them a quick rinse under cold water first, then toss them in the washing machine with your regular clothes, cold water, mild detergent, no softener or bleach. For drying: lay flat for medium absorbency styles, or tumble dry on low for high and super absorbency ones. That's it. No ironing needed!

Totally up to them! Every flow is different, and there's no wrong answer. Depending on the absorbency level and how heavy their period is, they can wear KT undies on their own or use them as backup alongside a tampon or menstrual cup. Whatever makes them feel most confident is the right call.
