We don't see enough panels in most knee warmers. Most knee warmers are a simple, single-panel tube with grippers at the top and bottom. Because it's part of the Giordana Body Clone FormaRed Carbon line, these knee warmers have to be different. Better. More complicated. While Occam's Razor postulates that simple is better, our simple knee warmers often feel like they're pulling at the kneecap and the pedaling motion seems to wear a hole on top of the knee. Being that fit is a hallmark of Body Clone, these warmers have extensive paneling. That means that the warmer won't feel like it's tugging your knees straight or slipping down while pedaling. And since it's part of the FormaRed Carbon line, you also get comfy, soft Aerofix grippers at the top and the bottom, with Liquid Elastic in both places. Both ends have a scalloped shape for comfort and fit. There is a second reason for all the paneling. Compression, which gives better muscle support, which delays fatigue, which allows you to ride harder longer which leaves a smile on your face for greater intervals. The paneling follows the contours of your muscles, allowing them to move, but also holding the muscles in place, which reduces the likelihood of muscle swelling from use. Giordana will probably tell you there's a third as well. The more a wicking material contacts the skin, the better it wicks. Take a top that's loose. Where the skin isn't in contact with material, sweat sits, keeping you feeling damp. Put a wicking layer next to that skin, and the skin stays feeling dry for longer. Super Roubaix material is a brushed nylon/spandex fabric that is smooth on the outside and lofty on the inside. The panels are held together by flat-panel stitching, so no seam can abrade your leg. There is a left and right, and are marked by reflective Giordana logos. All you need to know in putting them on is that the Giordana logo, printed onto the material goes on the outside of each knee, with the logo oriented so it's on the side of the tibia.
