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.

Great

With the insert they absorb a heavy flow. No smell or wet feeling. Super comfortable I would wear them not on my period. Without the insert I would wear at the end of a period, or if I had a lighter one. I am going to buy enough for a week.

Comfy

Wearing comfy underwear is essential for me during my period. I especially love wearing these for overnights by themselves or as back up.

Comfy!

I love the style of this. I was hesitant to buy it at first, because the regular briefs go way past my belly button. Way too high for me. I was worried these would be the same. But I'm pleasantly surprised to say they're not. They sit at the same height as the boy shorts. The band is super comfy and I have full butt coverage so no wedgies. Until they fix the crappy band on the hipsters, I think I'm going to stick to these.

Super comfy!

I already had the boxers, but I like these briefs even better! I use a menstrual cup, but my flow is intense and these make me feel less anxious about potential leaks. I'm also a trans person who uses a packer and even though I have a pouch to hold it, it feels more secure in these snug briefs. I overheat easily and during the summer, the boxers were a little too warm, I much prefer the briefs. I love the color too! My lower waist is ~31.5" (80cm) and my hips are ~36.6" (93cm), I usually wear size 30 pants and these fit me perfectly. The only thing that annoys me a little, is that I bought booster pads and I find that they're just a tiiiny bit larger than the space you slip them into and it tends to bunch up a little bit. Nothing major, but I'm autistic and I tend to notice these things more than most people. I took a picture of the underwear, but note that it's been used and washed 2-3 times already. Also, my camera doesn't want to capture the color properly. It's less blueish and more forest green leaning IRL. I put 4/5 for absorbency, but it's hard to really tell coz I've only used them with a menstrual cup and on the last day of my period.
