The Launch Pro D3O Elbow Guards build on the legendary performance of Fox's existing guards and elevate the performance to new heights. Designed with input from Fox's elite level race team, these elbow guards utilize D30 - the worldwide leader in impact reducing materials - and combine that technology with a removable hard cap for bulletproof durability and all mountain performance. The D3O CE certified build allows the elbow guard to stay flexible for ease of movement and comfort, but upon impact, they instantly harden to provide a hard shell-like protection. The Launch Pro D3O Elbow Guards have a breathable, moisture wicking construction, so they remain comfortable all day long. - Enhanced breathability through perforated, non-toxic, hypoallergenic Ariaprene neoprene - Anatomically designed panels provide superior on-bike comfort - Moisture wicking back fabric keeps you cool and dry - Removable/replaceable hardshell front cap to reduce snagging - D3O CE certified insert for impact protection
