The Alpinestars Sequence Knee Protector features CE-certified Level 1 protection. A dual strap closure system ensures the Sequence Knee stays in position, while the TPR pull tabs make it easy to close while wearing gloves. The shell is constructed from a high-performance polymeric material blend for optimised flexibility and excellent weight-saving properties. It is highly perforated for maximum breathability and air ventilation. The single-injected compound shells are constructed with a back-integrated grid structure that absorbs and dissipates impact forces. A soft bridge connector is placed in the middle of the shell to allow flexibility and adaption. Internal rounded thermoformed padding with additional viscoelastic foam gives the rotula the perfect fit and better protection. Abrasion-resistant microfibre is on the inner part (Bike side) for extra protection.
