For years, I struggled with thick and crispy sanitary pads before later swapping to single-use tampons — and still not loving them. Essentially, I wish period pants for teens had been an option when I started menstruating at 13, cutting any worries about leaks or running out of supplies while also looking super cute.
But since learning that 45 billion (!) disposable period products are used every year, with 500 million of those going to landfill, it makes me question why we're not talking more about the environmental impact of periods.
Although, let's not laden teens with eco-guilt just yet — particularly if they've just been blessed with the burden of a monthly visit from Aunt Flo. What we are offering, instead, is an answer all their FAQs on the best period pants for teens, as well as a rundown of the very best on the market. How can we say that with confidence? Because a team of GLAMOUR editors have personally tried and tested a range themselves. So whether she's after a bikini, a boyshort or has no idea at all, here are the best period pants to get her started.

What are period pants for teens?
Unlike menstrual cups or anything similar, period pants are exactly what they say on the tin: pants teens can wear during their TOTM (time of the month). They soak up everything — blood, urine, discharge or sweat — and keep it all contained, so they needn’t worry about leaking. And, if you/her are conscious of your ecological footprint, they’re also totally reusable.
“In recent years, people have become much more conscious of their environmental footprint with more emphasis placed on reducing our single-use plastic consumption and carbon emission contribution,” says Ruby Raut, CEO and co-founder of WUKA. “It's encouraging to see that this demand is being driven by the younger generations as well as adults. We've seen this first hand with our First Period Pack — a popular first choice for adults buying for their tweens and teens resulting in a +327% growth in sales."
How do period pants for teens work? Essentially, they have a built-in sanitary pad that she won’t have to discard every three hours. She literally can slip the pants on and forget about her period until the end of the day. They're also really discreet — they don’t give the nappy-like look that people assume they do.
But, according to Raut, a fear of leaking is what puts people off: “A lot of people are concerned they will feel like they're wearing granny pants – but they won't. There are so many different styles of period pants for teens: briefs, seamless, high-waisted, boxers and even thongs for the ultimate summer period underwear without the VPL."
How we tested the best period pants for teens:
As we're not teenagers, we GLAMOUR editors – each of different ages and flows – trialled the adult versions of the period pants for teens in this round-up. We tested them in numerous scenarios over many months and at various points in our cycles. We worked out in them, lounged in them, went on holiday in them, worked from home in them, and then we evaluated each pair based on six things: comfort, absorbency, how well they washed, whether they kept a fresh feeling, how they felt under normal clothes, and value for money. The results? See below.

Ahead, the best period pants for teens in 2025:
WUKA Teen Stretch Seamless Period Pants
Underwear style: Full brief.
Absorbency: Heavy flow, holding up to up to 4 tampons' worth.
Sizes: 2XS — S / S — L.
Colours: Black, navy, blue, red or light nude.
Machine washable? Yes.Tested by: Sophie Cockett, GLAMOUR Senior Commerce Editor.
Pros: The Stretch Microfiber Technology means these stretch to fit all body shapes. Plus, the CoolMax Absorbent Technology fabric in the gusset results in fast absorption.
Cons: On the thicker side — but that also limits the need to line it with a panty liner or single-use pad.
Why we love them: “For a VPL-free finish, look to WUKA's Teen Stretch Seamless full brief knickers, which aid my passage through period days like a dream. They're designed to grow with your teen — the two sizes stretch to fit most while also accommodating any physical changes (such as bloating and increased water retention) during her cycle. Having worn them under sporty leggings, high-waisted jeans and midi dresses, I can confirm they're never visible through clothes either. A game changer.”

Modibodi Teen First Period Kit
Underwear style: Hipster bikini.
Absorbency: Moderate, holding up to up to 6 tampons' worth.
Sizes: 8 — 10 years / 10 — 12 years / 12 — 14 years / 14 — 16 years / 16 — 18 years.
Colours: Black.
Machine washable? Yes.Tested by: Sophie Donovan, GLAMOUR Senior Commerce Writer.
Pros: The Set includes one pair of black hipster bikini pants, an exclusive illustrated comic strip, period facts and sticker kit, handheld mirror and a waterproof bag — all beautifully gift wrapped to take away the shame and stigma.
Cons: We're wishing for more print and colour options.
Why we love them: "I gifted this to my teen cousin a couple of years ago, actually before she started menstruating, as there's nothing worse than being caught without the necessary supplies.
"She still wears these hipster briefs to this day, usually on day three or four of her cycle when her flow is a little lighter. She loves how they're anything but bulky and the super-soft material. But she also really appreciated the easy-to-follow comic strip that let her know what to expect, both in terms of physical and mental changes during her cycle.
“Personally, I was most fond of the handheld mirror, reminding teens that it's healthy and normal to explore their body — especially when new things are going on.”

Absorbency: Super, holding up to up to 10 tampons' worth.
Sizes: 8 — 10 years / 10 — 12 years / 12 — 14 years / 14 — 16 years / 16 — 18 years.
Colours: Black or berry blossom.
Machine washable? Yes.Tested by: Lucy Smith, Former GLAMOUR Commerce Writer.
Pros: “I put these to the test on my heaviest period days, and they lasted me through the night every time. The absorbent pad, which stretches to your tailbone, provides extra security when lying down, too.”
Cons: “In my experience, drying these on the radiator will hinder their performance, so it's an air-dry only affair.”
Why we love them: "As someone who's woken up to that dreaded crimson stain on my white bed sheets more times than I care to admit, finding a solution to Aunt Flo's monthly crimes was top of my shopping list. Enter: Modibodi.
“We're three years into my switch from tampons and pads to period knickers, and I can say with complete honesty that these period pants have transformed the quality of my sleep. I no longer need to set an alarm to change my tampon or wake up at 2 am in a panic that I've leaked. I can even wear white jeans in the day, stress-free. So long, my period support pal, performing an honourable 'you're good' check as required.”
Underwear style: Bikini.
Absorbency: Heavy flow, holding up to up to 4 tampons' worth.
Sizes: 2XS — S / S — L.

Pros: WUKA has skipped itchy labels to ensure maximum comfort and has thrown in a waterproof changing bag to stow your spares.
Cons: Expensive — but consider it an investment in your menstrual health.
Why we love them: “What's worse than sitting in class only to be filled with that familiar 'I’ve just come on' dread? Luckily, WUKA's School Set kits your teen out with a pair and a spare, as well as a waterproof changing bag just in case you do need to do a quick swap. Holding up to four tampons' worth of period blood and stretching to fit up to three UK sizes, these are an ideal option for total beginners."

Colours: Black, wild west green or berry blossom print.
Machine washable? Yes.Tested by: Georgia Trodd, GLAMOUR Senior Commerce Writer.
Pros: Made from natural, renewable and super-soft Merino wool, and that 3mm lining is still very absorbent despite being super thin.
Cons: We'd like the legs to be a little longer to stop them from rolling up.
Why we love them: “Modibodi is a leading brand in the adult period pant realm, so it's no surprise it's now offering options for the younger gen — including some finished with a seriously cute western print. The Hipster Boyshort pants are the perfect absorbent undies to wear under her school uniform, skirts, dresses, or her PE kits — or at night in replacement of PJ shorts. An everyday staple for those with packed schedules and no time (or desire) to deal with disposables."

Next Teen Light Flow Period Pants
Underwear style: Bikini.
Absorbency: Light, holding up to up to 4 tampons' worth.
Sizes: 7 — 8 years / 9 — 10 years / 11 — 12 years / 13 — 14 years / 15 — 16 years.
Colours: Pink and orange twinset.
Machine washable? Yes.Tested by: Sophie Donovan, GLAMOUR Senior Commerce Writer.
Pros: Kept her tester (AKA my pre-teen cousin) dry and odour-free all day.
Cons: A fairly small absorbent zone, so we'd skip sleeping in these ones. We can also confirm they're not seamless.
Why we love them: "There's no denying that period pants are an investment, with the initial outlay far higher than that of a set of single-use sanitary pads. Thankfully, this set from Next works out at just £9.50 a pair and comes in the most fun neon hues. Absorbent pants don't have to be black. Period.
“Despite coming in a light and heavy flow option, neither are the most absorbent on the market — but that's easily fixed by layering with a single-use towel on heavier days, and the cotton outer has even grip that it'll stay in place.”

Underwear style: Seamless bikini.
Absorbency: Light flow, holding up to 2 tampons' worth.
Sizes: XS (UK 6 — 8) / S / M / L / XL / 2XL / 3XL (UK 24 — 26).
Colours: Black, dusty rose or beige.
Machine washable? Yes.Tested by: Georgia Trodd, GLAMOUR Senior Commerce Writer.
Pros: Made with recycled nylon, crafted from pre-consumer waste — like old water bottles and fishing nets. Eco credentials? Check.
Cons: Due to the high elastane content, they can feel a little tight at first, however, they will loosen after a few wears.
Why we love them: “These seamless period pants are ultra-thin, super smooth and truly invisible — as well as being slightly cheeky and super stretchy. They hold up to two tampons' worth of blood, urine or sweat. But the main reason these made it into our lineup? The insane size range, fitting everyone from a UK size 8 to 26."
Underwear style: Shorts and hipster.
Absorbency: Medium flow.
Sizes: XS-XXL.
Colours: Black.
Machine washable? Yes.Tested by: Georgia Trodd, GLAMOUR Senior Commerce Writer.
Pros: Double-layer inner gusset provides extra protection. Designed for up to 24-hour wear, making them ideal for long days at school, sleepovers, and school trips.
Cons: The set includes just one style of period pants.
Why we love them: “This is a great gift for the teen in your life who's just started their period. This pack would be a true lifesaver as it'll have her covered day and night for at least 48 hours, consisting of four pairs of bikini pants and a waterproof carry bag.
“As with most WUKA pants, these come fitted with the brand's patented CoolMax Technology — ultra-fast wicking and quick-drying fabric keeps you feeling fresh — Stretch Technology, meaning one pair fits three sizes. Do we wish there was more than one colour or style option? Yes, but that's our only complaint.”
Underwear style: Bikini.
Absorbency: Heavy flow, holding up to up to 4 tampons' worth.
Sizes: XS (UK 6 — 8) / S / M / L / XL / 2XL / 3XL (UK 24 — 26).
Colours: Black.
Machine washable? Yes.Tested by: Sophie Cockett, GLAMOUR Senior Commerce Editor.
Pros: That soft lace waistband makes these super comfortable to wear, day or night.
Cons: They come up a little small, so we suggest sizing up one.
Why we love them: "I hate when I feel sluggish and self-conscious when I'm on my period, but these lace-adorned period panties help fight the temporary uglies. They look just like my usual organic cotton underwear, except they offer up to 12 hours of leak-proof protection and hold up to four tampons' worth of blood.
“I've tested them during every possible scenario life can throw at you, and honestly? They win every time. I love how lightweight and stretchy they are. Oh, and if you need further convincing, 86% of reviewers said they avoided leakages in these period pants."
How much blood do period pants for teens hold?
Absorbency differs between brands and pant style, but as a general rule of thumb:
- Light: Up to 20 mls, or 4 tampons worth of blood, sweat and urine. Perfect for the start or end of your cycle.
- Moderate: Up to 30mls or 6 tampons worth, making them suitable for heavier days.
- Heavy: Up to 40mls, or 8 tampons worth.
- Super: Up to 50mls, or 10 tampons worth. Best suited to your heaviest days or overnight.
“You know your flow best,” says Ruby, but we also recommend trialling a few different options to work out what works for you.
Can you wear period pants all day at school?
Absolutely! The best period pants for teens are designed to keep you dry and odour-free all day. However, this is dependent on your flow and your pants' absorbency level. Just in case, we recommend carrying a spare and a changing bag to stow them in.
How to wash period pants for teens:
The good news: It doesn't take much more effort to refresh your period pants. In fact, we suggest you give them a quick rinse under the tap to remove any clots before following the same process as usual, chucking them in a cold-water wash (between 30℃ and 40℃) and leaving them to air dry. Try not to use fabric softener or bleach, though, as this will make them less absorbent over time.
Endometriosis is still taboo in the workplace — and it needs to change.
