FAQ

How do your period undies work?

Aisle undies feature a specially engineered lining that combines super-absorbent Truetex™ technology with a leak-proof lining to keep you dry and feelin’ fly.

Do Aisle period undies contain PFAS?

No detectable levels of PFAS have been found in our underwear, based on a detectable limit of one part per million.

FAQ Image

Do I need to wear a pad or tampon with them?

No need to double up for light days and minor leaks, but we do recommend pairing your thong with a cup or tampon for moderate-heavy periods.

Does it come with a booster?

The Aisle Thong was designed specifically for light flow needs, so we skipped the booster for this style.

How do I wash my Aisle undies?

Our undies were made to fit into your regular laundry routine. Just rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy and prolongs the life of your undies!

So cute

Purchased for my bestie. Also got her the base thong. She loved them both but these were her favourite. Perfect size and super comfy

Comfy and breathable

I prefer thongs for everyday underwear. In the past I've used thong-specific pads for when I want no pantylines but have my period. These thongs are nicer. The absorbency is part of the underwear and doesn't move around or go anywhere. The absorbent part is smooth and doesn't stick out compared to the rest of the underwear. I use it with my menstrual cup for medium flow days or by itself for light flow days (at the end of my period).

The only underwear I will wear

I love my boost thongs, I have enough pairs that I can wear them everyday. They are comfortable and breathable and I love the fact that I don’t feel like I have to give up my preferences and still be protected from small leaks or during my period.

The period undies I’ve been dreaming of!!

I’ve been looking for the perfect thong undies to wear. I’ve struggled to find a pair that fits snugly enough to be seamless under my clothes, but is still comfortable for daily wear. I finally found them!

These are snug when first purchased, but they become comfier with wear.

My favourite underwear!

I absolutely love my Boost thongs, and they are, by far, my favourite underwear. I find that they’re comfortable to wear, and, if I had enough pairs, I would wear them everyday. The added protection they provide keeps me feeling confident, especially during exercise, and being active outdoors. I have tried other brands of period underwear, but I don’t find that they are as good. Some other brands tend to stay moist, which feels awful. I find that Aisle’s underwear dries faster, and feels better! I highly recommend the Boost thong by Aisle. I am 5’2 and 120lbs, and the size small fit me well.
