The Feel3.7 RACE back protector belongs to the top in its class; the outstanding balance between far below CE Level 2 impact absorption and wearer comfort, due to its unique construction, lightweight components and ergonomic features are second to none. The patented Tryonic Vertebra joint system connects the Polypropylene outer shells forming a rigid impenetrable shield and at the same time allowing for an unsurpassed freedom of movement. The EPS inner core ensures maximum energy absorption (< 4kN energy release), well within the CE Level 2 norm (< 9kN energy release). The Feel3.7 RACE is probably also one of the most comfortable back protectors for high activity sports due to the Coolmax mesh in the back. As it performs up to minus 20 degrees Celsius, the Feel3.7 is the perfect choice for a variety of winter sports activities. The main difference with the regular Feel3.7 is that the Feel3.7 RACE has no shoulder straps but only a Velcro waistband as to make it comply with the rules for protection of professional athletes of the international ski federation.
