Best Period Underwear in Quebec: How to Choose (2026)

Updated September 2026.

The best period underwear isn't the same for everyone. Your best friend's favourite won't necessarily be yours: it all depends on your flow, your body, your schedule and your budget. Here are the 8 criteria that really matter when choosing in Quebec.

1. Your flow: criterion number one

Period underwear doesn't all have the same absorbency. Most brands rank styles by level (light, moderate, heavy, very heavy) or compare them to a number of tampons. Choose for your heaviest days, not your lightest.

Not sure if your flow is heavy? According to the Government of Canada's menstrual health guide, periods are considered heavy when they last longer than eight days, when you soak through a pad or tampon every hour for several hours, or when you pass clots larger than a toonie.

2. The cut for the time of day

  • Daytime, under fitted clothes: a cut with no visible seams that won't show under leggings or jeans.
  • Overnight: a fuller cut, with an absorbent zone that extends further at the front and back to prevent leaks while lying down.
  • Sports: a cut that stays in place, like a boxer or boyshort.

Many people end up with two styles: one for the day, one for the night.

3. Size: a close fit

Period underwear needs a snug fit so the absorbent zone stays in place. Too big leaves gaps; too small squeezes and gets uncomfortable. Follow the brand's advice: some run small, others fit like regular underwear. Since most brands don't accept returns on period underwear for hygiene reasons, take the time to choose well and ask questions before you buy.

4. Comfort and materials

The layer against your skin should be soft and wick moisture away so you feel dry. The underwear should also stay thin and not bunch up. Check the listed composition, and if you have questions about fabrics or treatments, write to the brand: a serious brand will answer clearly. Some also show textile certifications, such as OEKO-TEX, which can help you compare.

5. Care and drying

Good period underwear rinses in cold water, washes easily and air-dries in a few hours. Avoid fabric softener and the dryer, which damage the absorbent layer. All our tips are in How to wash period underwear.

6. How many should you buy?

For a full cycle without disposables, plan on 3 to 5 pairs, depending on your flow and how often you do laundry. You can also start with one or two to test, then add more.

7. Price, and your city's subsidies

In Quebec, a pair of period underwear generally costs between $20 and over $40. Price isn't everything: also look at absorbency, durability and comfort.

Good news: many cities reimburse part of the cost. Quebec City, for example, reimburses 60% of the pre-tax price, up to $100. Lévis, Longueuil and most Montreal boroughs also have programs. Check our city-by-city subsidy list before you buy.

8. A local brand that answers you

Buying from a Quebec brand supports the local economy, and it's practical too: service in French, faster shipping within Quebec and, in some cities, a higher reimbursement when you buy from a local business. Read customer reviews and see whether the brand answers your questions before you buy.

Independent tests can help

Quebec media have compared period underwear. Protégez-Vous, for example, evaluated about twenty period underwear and menstrual cups in 2022. These tests are useful for comparing absorbency and leaks, but keep in mind that your flow and your body remain the most important criteria.

Can you return period underwear?
