The well ventilated Receptor Flow has a slimmer design to sit more snugly around the head yet maintains excellent levels of rider protection.POCs pro-riders had requested a slimmer fitting helmet & the Receptor Flow is the result. The density of the EPS liner has been optimised to offer the best levels of protection & has increased thickness over the most vulnerable areas. The liner is protected by a tough PC in-mold shell plus the front of the helmet has a section where you can add on the optional Bankers Brim visor (sold separately). The fit is assured thanks to a sizes adjustment system so you can be sure it will stay comfortably in place during tricks in the park or over dirt jumps.
