These Tri shorts, made from only the finest of fabrics, boast the highest compression to comfort ratio in the industry. The perfectly sized antimicrobial, wicking micro-fleece pad with NeoGel provides superior comfort while cycling. Yet, it becomes second skin on the run. With its 84% nylon and 16% spandex composition, the Synergry Tri short insures semi compression for optimum performance.. It is important that the compression ratio is not full compression. As that is too constrictive for the thigh muscles during the cycling leg. Semi-compression gives support, while not being restrictive. Every seam is flat-lock stitched and the leg gripper is soft and effective, unlike the silicone grippers that can tear up your legs. The NeoGel pad is revolutionary because it provides as much support and comfort as a high end cycling pad, yet it is only 2mm thin and virtually undetectable during the run.
