Alpinestars BIONIC AIR Rib Protector

While this specific model is engineered with the ergonomic demands and impact profiles of karting in mind, its lightweight, low-profile design makes it potentially adaptable for other activities requiring rib protection. However, it is primarily optimized for the specific seating position and vibration levels found in go-karts.

Yes, the Bionic Air is designed to be worn either over or under your gear. The soft poly-lycra inner lining is specifically included to ensure it remains comfortable against the skin or a base layer, while the slim profile prevents it from adding unnecessary bulk.

The protector is highly adjustable to accommodate growth. It features a central back panel with hook-and-loop attachments, fully adjustable shoulder straps, and a front strap with a D-ring closure and elasticated section, allowing you to fine-tune the fit as the driver grows.

Yes, the 3D mesh is designed to promote airflow in areas where sweat typically accumulates, such as the shoulders. It significantly improves ventilation compared to solid fabric straps, helping the driver stay cooler during longer sessions.

This protector goes beyond simple foam by using a multi-layered construction. It combines a 3mm high-density poly-foam and 3mm EVA for vibration dampening with a rigid fiberglass core and PE hardshell to disperse energy from harder impacts.
