The Trabec in-mold helmet combines functionality and performance for single track and enduro riders who are in need of the highest degree of protection. The construction is similar to how a skeleton is build for both resistance and durability. The inner Aramid filament reinforced EPS core is tough and resilient while the outer PC shell is constructed with the seems located in the areas of least exposure. An aerodynamic channel system and 16 vent slots provides great ventilation while the fit is designed to be around the head versus on top, which promises superior protection.The Trabec Race model has extra aramid reinforcements.
