Amazing Period Underwear

I'm a huge fan of these sporty stretch period underwear. They've been lifesavers. I've tried different brands and these are the most durable and absorbent of them all. Plus, they are really comfortable to wear for extended hours. I'm happy to see Walmart started carrying new colors instead of just the black ones. After six months of repeat usage and laundering, I'm impressed at how well these hold up. Some other brands have already started losing their absorbing abilities or have small holes in them. These still look like new. Make sure to use the gentle/delicate cycle while laundering them. Rinse them before tossing them into the wash with a regular load and flip them inside out when drying so they dry faster. They don't recommend using fabric softener. Apparently it can reduce the absorption rate. I'm not sure if that's true but I've been following the directions as a precaution. The sporty collection has multiple materials, mainly synthetic, like nylon and spandex in it. Always check the label if you have sensitive skin or textile allergies. If I had to nitpick, I would prefer slightly more coverage at the front. I don't know why but all period panties seem to lack frontal coverage even though periods can flow forward. If you're a stomach sleeper that's something to take into account when deciding on which product to use.

Great period underwear

These period underwear are great! The absorbency is good enough for heavier flow, even overnight, for me. The fit is comfortable as well. I plan to get a couple more pairs to have some to switch out while the others are washing. The only thing I'm unsure of it how they will hold up. But I am very pleased with them so far.

I use this for light bladder leaks. I hated using disposable briefs. I did try other period panties before this brand and I feel this is the best value for the cost. Other brands are more expensive and tend to loose shape after multiple washings. These are comfortable, breathable and lightweight. They are very absorbent.
