The Charles Owen Pro II Plus Skull Hat is the only triple-standard, precision-fitting cross-country skull cap that can take a removable liner, which allows for a close and customised fit. This liner can be easily removed and washed, to keep your head fresh and clean.This hat has been designed with front and rear ventilation slots for superior cooling and a GRpx® technology harness for unsurpassed stability. The offset ventilation holes also help to prevent horse studs penetrating through the helmet in case of a fall.Lightweight but highly protective, Charles Owen helmets are constructed to remain in place while riding and in the event of a fall. The Pro II Plus grips the occipital bone, which is located at the base of the skull, so that it cannot shift and alter the area of protection offered.Safety Standards: Kitemarked to PAS015:2011, Kitemarked to VG1 01.040 2014-12 and Certified by SEI to ASTM F1163-15.Please ensure you are purchasing a hat with the correct safety standards for the disciplines/riding bodies that you are intending to use the hat for.Replacement liners for this hat are available HERE.
