Terms & Policies
Please see each product page, for individual sizing.
As a general rule, please choose the same size for our period undies and period swimwear as your child's regular underwear size.
Our period underwear is designed here using Australian Child/Youth underwear guidelines. It's important to note that child sizing, also crosses over into women's sizing at our 12/14, so we have also shown this on our sizing charts (on each individual product page) to assist.
We also understand purchasing online can make judging sizing difficult and everyone has a different body shape (literally hundreds of waist & hip combinations) so we have created guides on each product page to help you choose the best fit for each product, or feel free to email our helpful team at theteam@knicked.com.au with waist & hip measurements so we can assist further.
To measure against existing underwear: use the flat lay measurement (side seam to side seam on the waistband) to compare with their current underwear.
Don't panic if you do find you've ordered the wrong size, KNICKED will happily exchange sizing and also cover the postal costs to reship (once per order) as long as underwear has been tried on over clean underwear and returned in AS NEW condition (not washed/worn free of lint/hair/marks), and packaging in original condition.

Knicked Boyleg™ Period Underwear with Pockets
4-Way Heavy Protection with Practical Pockets
Heavy flow? Side leaks? Need pockets? School uniforms?
We've got you covered.
Our Knicked Boyleg™ period underwear is designed for heavier days with absorbency in ALL 4 directions - front, back, sides AND down the inside leg. Plus, they feature 2 sleeve pockets perfect for your phone, money or keys. These are perfect own their own or under school uniforms and netball skirts.
💖 What Makes Them Different?
Unlike regular period underwear, our Boyleg with Pockets features:
✔ 4-way absorbency protection (front, back, sides & inner leg)
✔ Heavy absorbency for all-day protection
✔ 2 sleeve pockets for phone, money or keys
✔ Thinner & faster-drying design
✔ More fitted for wearing under uniforms
✔ Super soft cotton blend
✔ Boyleg style for extra coverage
That means total protection from every angle - even if you've leaked over the side of regular period underwear before.
👍🏼 Perfect For:
• Heavy flow days
• Under school uniforms & netball skirts
• All-day wear
• Side & leg leak protection
• Anyone who needs pockets
• Tweens & teens with heavier periods
🌿 Designed for Real Periods
Created by a mum, designed for heavy flow.
Our Boyleg with Pockets is:
• Heavy absorbency (4-way protection)
• Reusable & sustainable
• Super soft & comfortable
• Practical pockets included
• Made to keep you dry and confident
Because heavy periods shouldn't mean leaks, limits, or leaving your phone behind.
Knicked period undies have always been and will continue to be FREE FROM NASTIES such as PUL'S (plastics) or PFAS (chemicals).
Please Note: These have a shorter absorbency area front to back. If you need more protection (front or back bleeder), we suggest purchasing the UltraGuard style which have complete protection from front waistband to back.


* Our teen model wears a ladies size 8 (teen 12/14) waist: 68cm hips: 89cm
* To measure against another brand of underwear please use the flatlay measurements - side seam to side seam along the waistband.

They look like they will be super comfy, just arrived today. A bit thicker than I thought they would be but love the additional pockets for the essentials.
After trying what feels like all the other brands, my AuDHD sensory sensitive daughter likes Knicked the best. The seams are less 'itchy' and the fabric that little bit softer than the rest.
Comfortable, just like wearing bike pants and they don’t leak. My daughter is extremely satisfied and wants me to purchase more pairs.
I purchased for my daughter. They are great. No leaks. She doesn't like boy leg period undies usually. But these are different with the absorbency down the leg.
Super comfortable and discreet - just like bike shorts with side pockets too!
Thank you. My daughter loves them and is using them for continence issues.
My teen has sensory processing disorder. She really struggles with many different types of materials and designs. We have bought many different brands and styles before. By far this boyleg style and material is most suited to her sensory needs. The boy leg style doesn't ride up and sits flush up against exercise pants. Thank you very much for your product.
I purchased these as the look for all the world like the Nike shorts my daughter wears under her school and netball dress. They are amazing. She’s SO comfortable in them No leaks. Very firm in a positive secure way around her middle and the legs don’t ride up. AND - a pocket!!
As a slim size 6-8 girl we tried both 10-12 and 12-14 but settled for the smaller ones. Thank you for a great product.
I looked a lot to find these! They are awesome! My daughter feels so secure in them. She even went to her dance classes in them and felt safe from leaks. The fact that the absorbent part goes right up the back and front and then down the legs is genius. A great product. We will be buying more of these.
Working great so far! Lasted my daughter a whole school day! Wish we could get them faster here in the USA but understandable!
Thank you for this product. My tween daughter gets reasonably heavy periods and was finding her regular period undies leaking/wicking on the inner leg. Ideally she would love to make it through a school day without having to change her period undies. These have been great and got her through. She is happy she can wear them under her netball dress too. She hasn't used the pockets yet but it's a nice touch if she needs to. Thank you!
After buying two pairs of the period sleep shorts I found that my daughter really liked them, and came back to order another 3 pairs. She is only new to having her period and still figuring out what works for her, and has been experiencing some leaks at night time so I bought her these hoping they would help. They have been a great purchase.
I ordered these for my young teen and she says they are her favorites out of the 4 brands we have tried!! Soft and comfortable while giving her the protection she needs. Will be ordering more.
My daughter experienced leakage with some other brands which led her to sometimes wearing 2 pairs! But these are great because they are absorbent down the inside of the leg. She feels much more secure and protected with this design. I will be buying more soon!
The higher absorbency appealed to me for the peace of mind and not having to change period undies half way through the day. Also the shorts mean no VPL which was also another great plus compared to the regular period undies I had been using. I also showed these to my daughter as a good option for when she starts her periods and she agreed they looked good so I'll be back to buy some more when her time comes.
My 11yo has a very heavy period and also plays alot of sports. These bootleg period undies are the best we have come across, they keep her comfortable and dry with no leaks.Thank you so much.
Great product that works. Super comfy too for the fussiest teen xx
An excellent product! My daughter loves them!
These are fabulous. The fit and coverage are by far the best I've found so far.
My girl loves these shorts, she is not a fan of normal breifs, so these are perfect for an active girl! Will be ordering more soon!
My daughter loves them as they are close to bike shorts to wear under sports uniforms. Also they dry alot faster than others
My daughter is a boy leg undies kinda person .. before we brought these she struggled to find comfort with pads on her normal boy leg undies. I brought 3 pairs at my first purchase not knowing the product but was hopeful they’d work great. And I was glad I did.
She loves them & wears them confidently with just a tshirt over the top even when she doesn’t have her period. She loves the 2 pockets too .. it holds an iPhone plus with ease.
These are great for school as on the heavy days you can put a no wing pad on top so during the day on heavy cycles she can take off the pad once it’s full & still have protection for the rest of her school day.
She washed these herself after every use as suggested & it doesn’t weird her out at all.
