YOYI FASHION Women's Period Underwear - 5 Pack Leakproof Menstrual Panties | Jacquard Fabric, Easy Clean | US Size XXS-5XL (Fits 12) | Comfortable for Sleep, Workout & Daily Wear

I was interested in Thinx underwear, because I have an issue with leaking out the back of even really long overnight pads at night. It can be quite stress inducing if I'm staying at a friend's place or a hotel. So I figured these were worth trying because they're a similar idea to Thinx and way cheaper. These work great for that purpose. The lining in the back goes all the way to the waistband, and pretty far up in the front. They don't absorb much, they more just provide a leak-proof barrier. So I usually wear them with a menstrual cup. At night I wear them with a menstrual cup and a reusable menstrual pad (I have a super heavy flow) and they've saved me from getting blood on my sheets several times in the past few months. They are very high-waisted, ending about an inch and a half below my belly button which may annoy some people. However, I love how secure it makes me feel. If you listen super closely, they do make a slightly swishy sound when you walk, but not enough to be noticeable to anyone else. They also feel good quality, but I haven't had them long enough to tell how well they will hold up over time.I'm tall, with thin legs, average hips and stomach and a slightly above average rear. I usually wear a size 12 in pants and a size large in underwear, and the US size large in these fits perfectly. My only caution would be that if you have thicker legs or wide hips, the leg openings might be a bit tight. However, since that's not my body-type, I can't say for sure.Overall, great back-up to another form of period protection.
