Customer Reviews
Customers say these period underwear are comfortable, thin, and provide excellent protection without feeling bulky. Many appreciate the no-show design that works well under leggings and dance costumes. Users find them particularly effective for heavy flow days and overnight wear. The underwear features appealing colors and patterns that teens enjoy. Some mention they run small and recommend sizing up. While most praise the leak protection, a few note occasional side leakage or wish for more back coverage. Common feedback includes their durability and how they boost confidence for active teens in sports like gymnastics and dance.

Your questions, answered.
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!
Good news, period underwear and pads are exempt from federal sales tax in Canada, and most provincial/harmonized sales taxes too. The exception? If your order ships to (or you're shopping in a store in) British Columbia or Manitoba, a 7% PST applies. Saskatchewan, it's 6% PST. Still have questions? We've got more info here.
Each pair has a built-in liner that absorbs period blood, no pad or tampon required (unless you want one!). KT Period Underwear comes in light, moderate, and heavy absorbency so your teen can find what works best for their flow.
Ultra: Absorbs the equivalent of 7-11 super tampons. Our longest front-to-back liner, designed for their heaviest flow days and overnight protection.
Heavy: Absorbs the equivalent of 4–7 super tampons. Great for overnight or the heaviest days when swapping into a fresh pair isn't always an option.
Moderate: Absorbs about 2.5 super tampons' worth. A solid go-to for medium flow days, discharge, and sweat.
Light: Absorbs about 1 regular tampon's worth. Perfect for spotting, lightest days, discharge, and sweat.
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.
Because these are underwear, we can't take back worn pairs, but here's the good news: you can try one pair from your first order risk-free for 30 days!
