The K2 Thrive Helmet has a unique design with a visor that protects the head with an extra touch of style and is very comfortable. The hard shell is built to last and protects against impacts thanks to lightweight EPS foam coupled with a durable, injection-molded ABS shell. Channels on the inner surface of the EPS direct airflow between your head and helmet, removing moisture and excess heat for all-day comfort. The comfortable, washable, full-coverage, breathable lining design wicks away moisture to prevent overheating and perfectly complements the K2's fit and sound systems. The K2Dialed™ fit system creates a personalized fit, regardless of your head shape. The ergonomically inspired three-point adjustable interface maximizes fit and customization with the simple turn of a dial. This allows for the ultimate convenience of being able to make adaptive changes on the fly.
