Sweet Protection only makes one helmet that"s more protective than the Rocker Helmet, and that"s the Rocker Full Face. Unless you"re charging waterfalls the size of a small building, the standard Rocker is enough for the biggest challenges in the river. Sweet used a unique combination of thermoplastic and carbon fiber to make the shell softer at the crown and more rigid toward the sides. Coupled with the high-impact, low-weight EPP foam inside, this combination of material allows for the most versatile impact protection from big, low-speed hits and small, high-speed bonks. All in all, you get a lid that fits like a glove, drains quickly, adjusts in mere moments, and keeps your skull safe in the whitewater when that"s all that matters.
