MP X-O Cap
The MP X-O race swim cap is engineered to reduce to drag, especially along the hairline and along the back of the head, for the most streamlined movement through the water. The dual density zones provide the perfect ergonomic wrinkle-free fit while internal dimpling ensures it stays in place throughout the entire race. To improve the hydrodynamic shape of the head and hair, the X-O swimming cap is designed to be used with the ultra flat Compression Cap. Medium Size.
