Fox Enduro Elbow Sleeve Stay agile, stay protected The Fox Enduro Elbow Sleeves are designed for riders who earn their turns and pedal up before sending it back down, and who need a lighter-weight option for protection on technical terrain. The Enduro Elbow Sleeves feature high-tech D30(R) protective inserts that harden upon impact, while staying flexible while taking on technical trail sections. The lightweight slip-on design of the Enduro Elbow Sleeves helps to reduce bulk, with a micro-Lycra stretch design and silicone grippers at the top and bottom to keep the sleeves secure. A nylon mesh rear panel increases airflow, keeping the air moving so you won't get bogged down while pedaling uphill.
