The most comfortable period undies on the market that actually do what they are supposed to do. I have already placed my third order because they are incredible.

The Fri Period Boxers are sooo comfy! They feel just like lounge shorts but with the bonus of amazing leak protection. Super soft, breathable, and perfect for those days when you want extra comfort without sacrificing security.

Amazing!!

I bought these after my favorite organic cotton pads were discontinued. I struggled to find a replacement that was comfortable and didn't leak. I finally got tired experiencing leaks from pads shifting and crinkling. After a ton of research, I finally came across these. I knew I wanted a boxer style for overnight. These were one of the only brands I found that actually used cotton in the gusset, which was very important in my search (no polyester for me, thank you). I absolutely LOVE these. I have been converted. I really worried that these would feel bulky or damp, but I really just feel like I'm wearing comfortable underwear. They are so much more comfortable than pads and feel much more secure. I highly, highly recommend! I even stayed up late doing a load of laundry because I only had two pairs and wanted to wear them again. I will definitely be ordering at least two more pairs and likely also getting the regular panty style.

The only thing I would mention is the elastic was a bit tight on my during the first day of my cycle when I was bloated, but I'm not sure if there's any way that could be remedied other than sizing up (which I didn't want to do because I wanted to ensure they were snug everywhere else). Otherwise, I have no complaints!

Extremely comfortable, seems plenty absorbent.

I've only had to use these once so far so hopefully I'm not jumping the gun on a 5 star review...my last cycle wasn't quite as heavy as usual...HOWEVER, the absorption seemed VERY good. Usually after a whole day of wearing my thinx, while they absorb pretty good, I tend to leak out the sides a bit. The gussets in my thinx don't do a great job of keeping fluids directed away from the clothes you're wearing; I felt like I was constantly transferring blood onto the insides of the pants or shorts I was wearing. I did NOT have that problem once in these.

Also, SUPER comfortable.

I am so happy I gave these a try because so far that are making me a really happy customer.

Bought this for my female friend because she hated products and she said and i quote “so comfortable love the feeling of freedom not having to worry about when to change a pad or tampon and theres zero smell at all” so if you were thinking about buying DO IT 100/10 definitely buying more
