FAQ

How do your period undies work?

Our specially engineered lining combines super-absorbent Truetex™ technology with a leak-proof lining that absorb 4 tampons worth of fluid. Use the removable booster for an additional 4 tampons of absorbency.

Do Aisle 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?

It’s not that complicated - our undies were made to fit into your regular laundry routine. Just rinse out in cool water, then wash and dry with your regular laundry. As with any garment, wash with like colors.

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.

I’m a believer!

I was skeptical that a thing could be leak proof. But this thing made me a believer! It’s comfortable, looks nice, and actually works.

Shrunk pretty bad, otherwise good

My only complaint is that they shrunk pretty bad. I am a true size 6, and sometimes a size 4 at the odd store so I thought a size small would be good. They for perfect when I first got them, but after washing, too sung and dig into my skin. The small in the boy shirt style worked though even after washing! I got coloured fabric which I was shocked did not even get stain even after leaking, even though there aren’t suppose to be PFAS. Was nice!

Lastly, I used this without the booster liner added. I would not add a boost liner to the things, it would just be way too bulky! I also thought the thongs came with a booster but they do not!
