With a name derived from "Trabecula" - the grid-like structure that adds strength to human bones and other organs - the POC Trabec Bike Helmet delivers next-gen protection and durability for XC and Enduro riders who like their riding with a little spice. The EPS liner of the Trabec is strengthened with an Aramid grid during molding, and the helmet has added coverage in the temples and back of the head in comparison with a traditional in-mold design. An adjustable fit and visor and a ventilation channel system with 16 huge vents keep you comfy and let you concentrate on the trail ahead.
