What sets this jersey apart from all the others is the use of woven Cocona particles from 37.5® Technology. Those incredible, little particles attract humidity and use your body heat to rapidly transfer perspiration from the interior to the exterior of the garment. This rapid transfer of moisture ensures a regulated body temperature and can increase athletic performance by as much as a 25%. The form fitting, Euro-length, mesh sleeves are an aerodynamic, no flap fit. Mesh in back panels helps regulate body temperature. The biggest advantage of a locking zipper is the ability for the wearer to singlehandedly unzip and open their jersey for venting. Merely flip the pull up to unlock the zipper. Then, with one hand, the jersey can be pulled open. Flip the pull back down to lock the zipper pull in place.   In a study done by scientists at the University of Colorado Boulder, thermoregulation clothing with 37.5 Technology was scientifically proven to increase athletic performance by up to 26% by reducing the increase of core temperature during activity. Proven to decrease the rate of core temperature buildup and keep you cool more effectively than wicking. Scientifically proven to increase stamina by reducing the amount of energy used to manage core temperature. Proven to increase efficiency so you use less energy to do the same amount of work. Featuring 37.5® Technology and lightweight, stretch mesh construction, the Men's Summit Aero Mesh Jersey provides breathable comfort and c
