K2 Diversion Ski Helmet 2018 - Men's Other The 2018 K2 Diversion Helmet is a perfect blend of comfort, safety, and convenience. Appealing to many skiers, the Diversion is a great example of a hybrid-style helmet because of its adjustability, convenience, and construction style. The human head is like a snowflake-no two are the same. When it comes to cramming your dome into a hard-shell helmet, there needs to be some customizability, otherwise there will be discomfort. Fortunately, K2 has come up with some innovative solutions to these problems. It's a bit long-winded, but K2 calls it their "360 Boa K2Dialed Fit system." For you and me, that means that there's a simple dial on the back of the liner that adjusts a band that circumnavigates your head. It tightens or loosens 360 degrees around so that there's an infinite amount of micro adjustments that can be made. For those skiers who can't live without their tunes, there's an audio jack on the back of the liner, so all you have to do is plug and play on your favorite device. The real reason for wearing a helmet, though, is for safety. In this regard, K2 holds nothing back. They use a hybrid construction method with primarily in-mold construction that makes the helmet very light weight. The secondary hard shell upper utilizes Active Matrix Venting and is more durable. Skiers of all ages and ability types will love the safety, comfort, and convenience of the K2 Diversion Helmet.
