So much protection and a lot of comfort, I felt secure, and I liked that the pad stayed close to my body.

This is my absolute overnight favourite leakproof underwear. It is comfortable but also feels so secure. It just stays in place so well throughout the night. I would fill my drawer with these.

Loved the fit - was surprised by how good they felt when worn, as they looked quite bulky off body. Felt quite seamless under my clothes.

I like the front and back full coverage making me feel extra secure if 1 were to wear it on my cycle. Very comfortable and not bulky The extended gusset makes me feel very secure, especially when in bed or on the run I really felt like / was covered, there was no doubt in my mind that I would have a leak. like the overall fit. It feels very smooth on the body and the full gusset feels very secure

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 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.

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.
