Fox Youth Enduro Knee Sleeves Pedal hard, stay protected The Fox Enduro Knee Sleeves are designed for young riders who like to earn their turns and pedal up before sending it back down or those who are in search of a lighter-weight option for protection on technical terrain. The lightweight slip-on design of the Youth Enduro Knee Sleeves helps to reduce bulk and make for a lower-profile guard and the padded protector is flexible, to maintain freedom of movement. The high-stretch fabric at the rear of the guard is breathable, while the perforated neoprene material on the outside of the arm increases airflow, so you won't get bogged down while pedaling uphill.
