SO very comfortable with zero leaks. I also really appreciate how Aisle stands behind their long-held reputation of offering high quality products. After years of using their pads, I wanted to try the period underwear and bought my first BOOST Brief on sale. I received a pair with a couple of small holes in the seams, presumably due to a manufacturing error. I contacted the company and even though my order was final sale, they responded immediately and promptly sent me a free replacement.

I like the look of the underwear and that you can modify the absorption level with the booster insert that it comes with. However, there is a prominent seam half way up the butt that is so uncomfortable with sitting for longer stretches. As I work a desk job, this gets so uncomfortable and ends up leaving a painful mark. This seam is also visible through thinner pants and leggings. I would suggest to the designers that they make the seam less prominent OR (even better) run the material all the way up the back like some other brands are doing.

Love the overall coverage with these briefs! I was confused with the extra "pad" lining but think it will come in handy on those heavy days (you can always remove it if you need to). Thank you for offering a great quality product where, while wearing, I don't have to worry about leaks or if I'm going to be supported. 100/10 would recommend Aisle period panties!
