This is the Air Management System version of Wilson's MLB West Vest Pro Gold 2 models. It maintains the A3210 model's thick protective aerated foam padding and contoured plate patterns popular for many years with umpires at every level.
Upgrades include a premium harness that will hold your chest protector to your body, magnetic self-fastening buckles called Fidlock buckles, and adjustable and/or easily removable pec wings that won't have you adjusting them after you throw each ball back to the pitcher.
Designed differently from other umpire chest protectors, Wilson Pro Gold 2 Air Management Chest Protector is available in 3 general chest sizes and lengths. This makes the Gold Pro 2 a good hard shell choice, especially for umpires with a smaller frame body type. Sizes available are based on coat sizes and lengths.
