Thinx finally did it!
I’ve been using Thinx for a few years now. They were the only name in the game for a bit but now have some competition. I am extremely active and only want breathable comfort. I’ve used their sport and cotton briefs but they’re hot and definitely not as breathable as I want. They don’t cover or stretch as well as I want either. Thinx Air is a game changer. I was researching alternatives but the Air brought me back. Buying a second (maybe third) pair! SO stretchy and light and perfect for really active women. I can’t remember the last time I wrote a review on Amazon. This one was worth it.

Every Woman Must Own
I skeptically bought this. Wow. I will be sure to have a pair ready for my girls when they get to this stage of development. What a relief to not have to worry about being embarrassed!!!! What an amazing new era my young girls will be stepping into! We have come a long way from belts and bulky protection. I will be buying more and the swim bottoms. We all deserve to conduct our daily lives with confidence no matter where we are in our cycle.

Better than expected
This is my first pair of period panties. They were comfortable and worked better than expected- no leaks and easy to clean.

Where have these been all my life?!
I’m totally converted to period underwear after trying these and wish I would have tried them sooner! Absorbency was great and I haven’t had any leaking. I want to buy more pairs and just wear these the whole time I’m on my period.

Perfect for light incontinence during exercise
I purchased these as a solution for light incontinence when running. I needed something absorbent, but that fit just like regular underwear and wouldn’t cause chafing or bunching even when running decent distances, and that would breathe well even during high humidity conditions (ie lots of sweat). These are perfect. Like, decade-long problem solved. I no longer need to dehydrate myself all day in order to run in the evening.

Lightweight!
Works well for Arizona summers, but only for LIGHT PERIOD DAYS!!! Definitely DON'T use it on medium days because it leaks. 😳 Otherwise, I'm happy with the product.
