MATERIAL: EPS Foam, Polycarbonate, Nylon
FIT SYSTEM: TurnSys
VENTILATION: 19
ROTATIONAL PROTECTION: Lazer KinetiCore
CERTIFICATION: CPSC
ACCESSORIES: Action Camera Mount, Optional Universal LED

Features:

Magnetic Buckle
The magnetic buckle connects quickly and is easy to use with full finger gloves.

Action Camera Mount
Never miss a moment. Jackal KinetiCore helmet includes a built-in camera mount to capture all your favorite action-packed memories as they unfold. The helmet shell is designed to prevent the mount or accessory from intruding into the helmet in the event of an impact.

Eyewear Friendly
Recesses in helmet shape removes the pressure on inside of head caused by the arms of sunglasses.

Tailored Fit
TurnSys technology provides a perfect fit on the fly with a simple turn of the dial. The magnetic buckle is easily managed with one hand and gloves on, ensuring your helmet is ready to roll whenever you are.

Goggle Grip
The no-slip design on the rear of the helmet prevents the goggle strap from moving out of position.

Integrated Rotational Impact Protection
KinetiCore Controlled Crumple Zones absorb the force of both direct and rotational impacts in the event of a crash to re-direct energy away from your head, protecting you when you need it most.

LED Light Compatible
Increase visibility by attaching the Universal Lazer LED at the back of the helmet, so you're seen no matter what the daylight or weather conditions are.

Stay Cool and Comfortable
Cleverly positioned ventilation channels increase airflow to keep you from overheating. When wearing goggles, air is channeled into the helmet above your eyebrows, lowering the chance of your goggles steaming up.

Adjustable Visor (Space for Eyewear)
Visor adjusts up and down for improved visibility in technical terrain and to keep your eyewear comfortably on hand, with a secure grip to reduce the risk of a goggle slip getting in your line of vision while riding.

5-star protection rating
The Virginia Tech impact testing uses the STAR evaluation system to determine the helmet's ability to reduce linear acceleration and rotational velocity of the head resulting from a range of impacts a cyclist might experience. 5-star indicates the "Best Available" rating possible. Virginia Tech recommends the use of any 4- or 5-star rated helmet.

Lightweight Design
Built 13% lighter and with significantly less plastic than the previous Jackal MIPS helmet, its stripped-back design hits the sweet spot between protection and performance for a lid that's both more sustainably built and ultra-comfortable even on your longest rides.

In the quest for ultimate performance, you should expect more from a helmet than "just" superior aerodynamics and lean weight. The Elemento features a revolutionary, new design with advanced technologies to deliver the very best safety and thermal comfort no matter what you ride: road, cross-country, cyclocross, or gravel (or all four). Designed in collaboration with the INEOS Grenadiers Cycling Team, the Elemento is aimed at professional and semi-professional athletes. Expect new standards in terms of aerodynamics, ventilation, and performance; expect nothing short of a revolutionary helmet for training and racing. BE AHEAD OF THE GAME The Elemento has been engineered to be both super-aerodynamic as well as to allow high levels of ventilation, thanks to its innovative design and the introduction of various pioneering technologies, such as Fluid Carbon 12 and Multipod. Fluid Carbon 12's composite technopolymer absorbs more energy from an impact than traditional materials and distributes the force generated more evenly across the entire helmet. This benefit has enabled KASK's technicians to increase the size of the internal channels, which improves ventilation, while simultaneously reducing the size of the ventilation holes for improved aerodynamics. Multipod is KASK's proprietary 3D-printed internal padding. This elastomer material enables the helmet to better withstand the energy generated by linear and rotational impacts. Multipod functions isotropically, meaning it withstands the energy from impacts the same regardless of the direction in which the force is applied. The Elemento's OCTOFIT+ helmet retention system allows for a more fine-tuned fit to provide greater safety and stability. A reflective graphic at the back increases rider visibility. TECH SPECS: Materials - Inner padding material: Merino wool - Chinstrap material: Polyester - Shell finish: Shiny Standard Detail - Standard: CPSC 1203 Weight - Weight: 300 GRAM

The Mojito³ is unmistakable in shape and personality: it’s the ideal blend of performance, comfort and style. The design considerations are perfectly balanced to offer maximum comfort and optimal breathability even when the going gets tough. You know when you pick up the distinctive Mojito³ that you are putting on a legendary helmet. 

The elements are in perfect equilibrium: performance, aerodynamics and safety. The design leaves you in no doubt: Protone Icon is KASK's new classic, an exceptional helmet for road, gravel, cyclocross and MTB cross-country. Every aspect has been redesigned to push performance to the limits. REDEFINED GREATNESS A redesigned internal frame gives the wearer greater safety. Seamless technology joins the lower and upper parts of the shell to give it a refined, elegant look and improved aerodynamics. The new OCTOFIT+ adjustment system optimizes the helmet's comfort and stability, while a vertical stabilizer across the nape of the neck provides ergonomic neck support and delivers enhanced balance and a customized fit. Its large rotation cap coated in a special rubber increases finger grip, and a reflective insert in the rear helps keep the helmet's wearer even safer. The internal lining is made of CoolMax® fabric which, as well as being comfortable and quick-drying, is also removable and washable. As is standard with all KASK helmets, the Protone Icon has been developed in accordance with the KASK ROTATIONAL IMPACT WG11 TEST protocol, an objective, scientific approach to measuring the helmet's performance against rotational impacts.

Absolute freedom in the wild outdoors: every athlete deserves a comfortable, light helmet even during extreme exertion. Valegro, developed in collaboration with Team INEOS Grenadiers, offers extreme lightness and top-level ventilation even on the toughest climbs and hottest roads.
