Nearly perfect
Maybe not practical, but I wish they were 100% cotton. The gusset is also a little too wide for comfort. Aside from that, they protect well and provide security for periods with or without tampons, and those sneezes that sneak up on you out of the blue!

Our Leakproof Period Underwear features multi-layer technology that differs from style to style, but works to ensure you stay fresh, dry and protected. For example, in our Super Leakproof™ No-Show Bikini, the top layer wicks away moisture from your skin; the inner-layer absorbs the liquid and locks it in; and the outer layer keeps any liquid from spotting your clothes.
Depending on the size and style of underwear, the leakproof gusset ranges from around 7.5” to 9” long. Our Super Leakproof(TM) Underwear features a 25% bigger gusset, with more of the coverage in the front of the underwear. For overnight leakproof protection, our Super Leakproof(TM) Dream Short gusset ranges from 10” to 14” long.
