You have not seen panties like these! The outer material is made of PUL, a waterproof material that is so incredibly soft. The inner material is even softer and wicks moisture away from the body. The panty fits like a glove so there is no extra bulk. A bow indicates what side is up and there is a lot of Velcro to help with the perfect fit. The bow snaps off so you can wash the panty in hot water and then throw it in the dryer. Our Belly Bands are made out of the same material. To view the material choice number just simply click on the photo, or hover over each image with your mouse and the number will appear.
