"We’re in the talking about periods prep phase & I wanted my daughter to have a chance to wear period underwear. She picked the fun pattern & loves the way they feel. Having them in advance of her period starting gives us something tangible & fun as a conversation starter."

Your questions, answered.

How do I wash period underwear?

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!

Are leakproof products tax-free?

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.

How does period underwear work?

What do the absorbency levels mean?

Ultra: Absorbs the equivalent of 7-11 regular tampons. Our longest front-to-back liner, designed for extra-heavy period days, overnight protection, and light bladder leaks.

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.

Does my teen need to wear a pad or tampon with period underwear?

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.
