So comfortable

I brought these light absorbency boy shorts for my lighter days.
I have 2 days of moderate/heavy flow, and then 3 days of light, where I would normally switch to pads/liners.
I have worn them and they are perfect; very comfortable and just look and feel like normal pants, actually I think they are better. No digging in. I brought my actual size.
Now I know how good they are, I will be buying some more for my first couple of days of my period.
These are worth every penny.

Comfy and cute

I use a Nixit cup which has changed my life but just for security I like to wear a liner but I find them irritable to my skin. These pants are so comfy, don’t feel thick at all, you wouldn’t know they are period pants! They also look so cute and I feel really good in them.

Awful experience

I was sent an item that didn’t meet the description and filled in a return request on the day I received them but have heard nothing and no one will reply to my emails.

So for the menopausal, slightly leaky woman...

It's very hard to find a nice set of incontinence knickers, especially when being incontinent is something you only half admit to yourselves. Intermittently leaky. I ended up decided to give Flux a go because I couldn't find anything under the incontinence heading that I could bear to be wearing. I'm very much enjoying my boy shorts. They do the job. They boost my confidence. The make my days easier. I feel good in them. I can't answer these flow questions below, because they aren't for me. But apparently I have to to submit the review so I've gone for light which is a close to leaky as dammit. Someone, please change the questions!
