FAQ

How do period underwear 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.

How much fluid do they hold?

8X as much as a standard disposable! Our undies absorb 4 tampons worth of fluid on their own, or 8 tampons worth when you wear with the included booster

FAQ Image

What does the booster do?

Our undies absorb 4 tampons worth of fluid on their own, but if you need a little extra you can add the optional booster for an extra 4 tampons worth. Just tuck the ends into the slits at either end of the gusset.

How do I wash my Aisle undies?

It’s not 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.

Best Period Underwear Brand

Super comfortable, I love wearing Aisle period underwear. The quality is great, they work great, and the best part is that Aisle is against forever chemicals in their products. I started off with a different brand of period underwear, but when I discovered Aisle, I switched to them immediately. The number 1 period underwear brand in my opinion!

Comfort and style

I like this style better than the older pairs of hipsters that I have. I have a short torso and these fit me better. The band doesn't roll like they sometimes do on my boxers. My only problem is the booster doest stay in place well but I just end up using the reusable pads I bought here instead.

THESE ARE SO AWESOME! I’m normally wear a large (8/9) in underwear (I don’t like seams to dig into my skin), but I opted for a xl since these looked like a heft set of period underwear. Theses are so comfortable and leave me feeling super secure! Now if you worry about seeing seam bumps through your leggings I would not recommend purchasing these (I commonly don’t care about this but my sister is someone who would).

Impressed

Post-menopausal woman here with less control over my bladder. Wearing these when playing sports. They do the trick. More comfortable than a pad, comfortable underwear generally, and even stylish. Also, love the models which actually represent our society—racially diverse, different shapes and sizes, masculine, feminine. Why doesn’t every company do this?
