The Bauer Vapor X900 Hockey Shoulder Pads would have been considered a top of the line shoulder pad in any of the years past. Built almost entirely with AEROLITE Technology, these shoulder pads are about as discreet as possible! Bauer's AEROLITE Foam is about 30 percent lighter than comparable High Density foams, making it incredibly efficient in terms of the age old balancing act between protection and weight. The pads are supplemented with reinforced padding in key zones. For instance, you'll find added HD foam in the sternum and spinal areas, with PE inserts being added to the spine as well. The mobility factor goes up another notch on the Vapor X900 shoulder pads when you factor in Bauer's new Four-Way Free Flex Chest, as well as the return of their Free Flex bicep guards and arch support. Finally, Bauer's revolutionary 37.5 Fabric lines the interior of the Vapor X900, and dries your gear out up to 5 times faster than other liners.
