The 2020 Mens Anon Raider Helmet is simple protection, all thrills, no frills, and safe spills. Featuring the Anon Endura-Shell construction and a skate inspired design, the Raider is ding resistant and will stand up to the test of time. Classic fleece lining keeps your head happy and at a comfy temperature, and the ear pads are audio ready, meaning all you have to do is slip in some helmet speakers and you've got your tunes on the go without even feeling they're there. Endura-Shell Construction: Endura-Shell helmets are made from a two piece construction that features an injection moulded ABS exterior for long lasting durability and ding-resistant strength. Endura-Shell helmets are designed for use season after season. Passive Ventilation: Passive Ventilation channels integrated into the helmet draw fresh air in the front and pulls moisture out the back. These channels help reduce goggle fog and maintain a comfortable temperature. Simple Fit: All Anon helmets feature removable ear pads and liners, so you can run the helmet alone or with a beanie underneath without compromising comfort. Note your size at the point of overlap.
