The Rival returns for 2014 & is a great helmet from K2. The Rival helmet is a really lightweight & comfortable helmet with a clean & simple design. Its low profile In-Mold construction with EPS liner is premium for ultra-lighweight performance helmets. It has passive channel venting, which directs the air-flow between your head & the helmet, keeping it cool. What's great about K2 helmets is their Dialed fit system, just dial in your custom fit using the K2dialed fit system that is integrated with the liner. This liner is also removable, so you can wash it, which is a great feature & unique to K2.
