Thinx

I purchased three pairs of their heavy duty period panties and I am never going back to pads or tampons! I have worn them a few times now and they are completely leak proof! As someone with a heavy flow I worry about this as well as if I will feel "gross" after wearing them for a bit b it you feel nice and dry! I hand wash mine personally and they keep up great!

Speak is a company with two lines of products: Speax underwear for women's monthly menstrual cycles and Thinx by Speax, their line of underwear for urinary leakage/incontinence. I can only "speak" to the incontinence line. I've suffered from stress incontinence for years. My best bet was wearing bulky pads that chafed or wouldn't stay put. They were uncomfortable. Then, my urologist recommended Thinx by Speax. I was a bit skeptical and they were pricey compared to the inexpensive underwear I used to purchase (although, they're more in line with brands like Tommy John, price-wise). I decided to buy a few pairs to test them out. The crotch of the panty contains a special, absorbent fabric that wicks leaks away from the skin, leaving the panty (and you) dry through leaks. I believe their panties can hold about 8 tsp (nearly 3 Tbsp) of urine. There is absolutely no odor and I wash mine in the machine with the rest of my clothes. Now, I've stocked up (they have frequent sales) and they're the only underwear I'll buy or use. I haven't had to resort to buying panty liners or pads in over 2 years—and that's made up many times over for the price differential in underwear.

I also love their mission to help impoverished girls/women who can't afford menstrual products with their Speax line. Great Company and I haven't needed to replace any of the underwear I've bought: they are very well-made and come in a variety of colors, patterns, and styles. Their fit guide is really helpful in determining proper sizing and it was right on for me.
