How is sizing? How should I measure?
Jim Adams - December 26, 2018
Thank you for your inquiry Jim. The LS2 helmets have more of an oval profile, similar to that of an Icon helmet. Here is an Icon helmet fitment video I would suggest you should watch. https://youtu.be/00vMQEXF-RI And if you want to watch two seasoned veterans discuss helmet fitment, check this one out:

A new approach to the adventure motorcycle helmet category, the Pioneer leans heavily on LS2's successful Rally experience and offers the rider everything they need, and nothing they don't for serious, dirt focused adventure riding. The shell is constructed using LS2's proprietary Kinetic Polymer Alloy (KPA). This high tech material is strong, very light, and has just a bit of flexibility to help absorb energy. Three shell sizes are used to ensure a great fitting helmet that is as small and light as possible. The helmets flow through ventilation system ensures you'll stay cool and comfortable. A dual density EPS (Expanded Polystyrene) safety liner allows for state of the art energy absorption. The helmets comfort padding is covered with a breathable, hypoallergenic fabric that is removable and washable. The Pioneer uses a twin shield system which is a built in sun shield to shade your eyes from bright sunlight making this the ideal helmet.
