For the all-day shredder who's more focused on bagging vertical feet than having an over-the-top helmet, the K2 Rival Helmet offers top-notch protection in a simple design. This lightweight dome-protector boasts a ton of tech. In-Mold construction uses an EPS liner that's molded directly to a lightweight polycarbonate outer shell; it's construction for ultralight helmets that also offers industry-standard protection. This brain bucket fits snugly with the K2dialed Fit System, which allows you to adjust the fit of the inner liner with a simple twist of a dial at the back of the helmet. But it won't keep your head hot; passive-Channel Ventilation uses three large vents in the front, top vents, and back vents in order to direct cool air through the front and pull hot air out the back. And the Full-Wrap liner's breathable fabric moves chilling, sweaty moisture from the surface of your head so it can quickly evaporate so your head stays dry and warm. Simplicity, so you can focus on that steep and scary line in front of you.


If you're looking for a lightweight and low-profile helmet, look no further than the K2 Rival Snow helmet. In-mold shell construction yields a lightweight helmet you can wear comfortably all day long. Passive-Channel Venting#8482; keeps your head ventilated and comfortable without any adjustments. K2dialed Fit System and the Full-Wrap Liner system customize fit for superior comfort. K2dialed Fit System features an ergonomicallinspired 3-point interface that adjusts fit with a twist of a dial-perfect for adjustments on the fly. Full-Wrap Liner System cradles the head and offers a mesh panel that wicks moisture and breathes well. Adjustable chin strap won't cause irritation. Alloy goggle clip holds your goggles in place. The K2 Ally snow helmet complies with ASTM F 2040 and/or CE EN 1077 alpine ski and snowboard helmet safety standards.


This helmet might as well wake up in the morning and cook you breakfast before going off to shred all day. The Rival by K2 is so loaded with features that there isn't anything else to add except for a winning lottery ticket. Which you'll feel like you won the lotto right after you try that upside down whirly gig to your dome and walk away without the slightest of headaches. PRODUCT FEATURES: In-Mold: In-Mold is the premium construction for ultra-lightweight performance helmets and is characterized by an EPS liner that is bonded to a lightweight poly-carbonate (PC) shell utilizing a distinct molding process. Unlike Hard-Shell construction, the lightweight EPS inner layer of the helmet is fused directly to the thin PC shell during molding. The result is a super light and protective envelope with minimal weight. Passive-Channel Venting: Channels on the inside surface of the EPS direct air-flow between your head and the helmet, removing moisture and excess heat; keeping you dry and comfortable all day long. Available on all K2 helmets. K2dialed Fit System: The K2dialed Fit System creates a custom-fitting helmet no matter what your head shape. An ergonomically inspired three-point adjustable interface maximizes fit and customization with the twist of a dial. This allows for the ultimate convenience of being able to make fit adjustments on the fly. The end result of the K2dialed Fit System is customized helmet fit just for you. Full-Wrap Liner System: This full-coverage, washable liner features a crown mesh that wicks moisture and breathes where you need it to while snugly cradling your head, creating the unmatched fit of a K2 Helmet. The Full-Wrap Liner System is seamlessly integrated with our K2dialed Fit System and K2 Baseline Audio, creating the ultimate user experience. No gaps equals better fit and more comfort.
