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.

Nice but leg holes are too tight

Love the sea glass colour but should've listened to reviews saying to get a bigger size. I have the high rise briefs, boxers, and bikini styles in small but should have gotten a medium in this style. It digs in a bit at the leg holes.

Almost Perfect

They are mostly pretty comfortable, the material is nice, and I haven't had any issues with leakage thus far. The only thing that I don't love is the fact that the slot for the pad to go into is right across the middle of my bum. This may not really bother most people but for me it does annoy me, though I mostly am able to adjust to it throughout the day. Otherwise they would be five stars for me! Just wish the pad spot was back further. I ordered one size down from what the size chart said I was (since I remembered last time I ordered the boxers a size up and that was way too big). Thankfully they were just right.

Incredibly comfy

I saw other reviews saying that they actually wear these sometimes when they’re not even on their periods and I was a little skeptical, but I actually do that too now that I have them. They feel better than most of the underwear I’ve bought in my life. With the boost liner in it, it can hold probably more than 8 regular tampons worth. This was a lifesaver because I have a very heavy flow during some of my period and other period underwear couldn’t last me more than a couple hours and I couldn’t easily change them in the middle of the day. These also don’t shrink upon washing, bleed colors, or feel tight, restrictive, or bulky. Even though they can hold a lot of liquid it didn’t feel like I was wearing a diaper. I had much more peace of mind wearing these.

Ok but would love some improvements

I don't like the loose fabric - please sew in all the absorbent layers. It's not very absorbent without the "booster" but the fabric itself is not comfortable for sports.

I would also appreciate a wider and softer elastic waist band, like the type on mens underwear

Almost a perfect fit

I like the fit of these a lot more than the bikini pair I got previously, they sit higher which is better for my body. I find they do cut into my love handles a little bit but it's not uncomfortable just an awkward line under pants.

For using the booster I like to slide it fully inside the "pocket" instead of just tucking in the ends which works great on the boxers but the middle gusset is a little too narrow on these and it can cause bulking.

Otherwise they're the great quality I know and love from aisle!
