The Anon Thompson Helmet shamelessly integrates every feature you need for a comfortable, well ventilated ride. The Hybrid 5050 shell construction incorporates endura shell at the top for optimum protection and a lightweight in mold construction along the bottom for a lightweight feel, so you get top level protection without feeling top heavy. In order to allow you dial in that perfect fit, Anon integrated a Boa fit system, so you can make micro adjustments on the fly with just the turn of a dial. Realizing that ventilation is a key element to any helmet, the Thompson is fitted with the Active ventilation system, which pulls air in through the front of the helmet through the rear vents, and is fully adjustable, so you dial it back on those cold days when you need to keep the heat in. The magnetic Flidlock magnetic snap buckle makes it so you don't have to fiddle with the buckle, and Skullcandy ASFX audio compatibility means you can integrate the Skullcandy sound system when you feel like turning your helmet into a surround sound system.
