GLX Silver Stria Motorcycle Half Helmet (X-Large)

The GLX 501 series are all equiped with a low-profile, sleek presentation and narrow look combined with an lightweight ABS injection-molded thermoplastic shell. The one thing that sets aside our half helmets from everybody else is that we offer soft and comfortable polyester liner which can be removed and or replaced. Sizes available from XS-XXXL.
