The chest protector features Cell Technology chest and back protectors and Level 1 CE/UKCA certified Nucleon Flex Plus shoulder protectors. Designed specifically for youth riders to offer optimum ventilation and lightweight.

Mounted on breathable padding, the open grid structure of the chest and back protectors is engineered to be both ultra-lightweight and ultra-breathable, while still guaranteeing unrivalled protective performance. The chest and back protectors are securely held in place via adjustable shoulder straps while lower securement is actioned via the easy-connect buckles and elastic side straps.

The removable shoulder protectors are mounted on a soft-touch foam padding and are attached to the main chassis with hook and loop patches. The elastic upper arm adjustment straps keep the shoulder protectors securely in place.

YNS compatibility is achieved by removing the EVA back puck panel and engaging the elasticated YNS pull tabs.
