The Troy Lee Designs Youth Speed Elbow Sleeve is a full-length sleeve designed to protect the arms of budding mountain bikers on the trails. Constructed from sturdy, 4mm D3O® abrasion resistant material, silicone grippers ensure it will stay right where its most needed. Despite its hardiness, young shredders will find this ultra-light sleeve breathable and comfortable enough to forget about all day, thanks to its flexibility and the inclusion of a breathable mesh panel. It will remain wonderfully supple right up until its strength is demanded, when the D3O® will harden to disperse energy and keep budding MTB aficionados safe.
