509 Altitude Prizm Motorcycle/snowmobile Helmet - Large - Medium - New-dot/ece on 2040-parts.com

We just raised the snowmobile helmet game to new heights. Or shall we say to a higher ALTITUDE.

Introducing the all new Altitude snowmobile helmet from 509. The Altitude helmet is the result of

a fearless desire to not only create, but innovate. It is the product of looking at every feature of our

previous Evolution helmet and asking the tough question, “How can we improve?”. The result is a

helmet designed and built from the ground up with 4 ideals in mind: Safety, Performance, Fit, &

Style. The Altitude helmet excels across the board.

SAFETY:

The Altitude helmet meets or exceeds DOT & ECE 2205 safety certification standards. It features

an innovative dual density, interlocking EPS foam liner that provides top crash protection in

the event of an accident. The front chin area of the helmet is protected by a specially designed

expanded polyurethane chin insert, that provides front impact protection. The outer shell is made

of a specially designed thermoplastic poly alloy material for maximum shell strength with minimal

weight.

PERFORMANCE:

In addition to it’s safety accolades, performance was a key focus during the development process.

Innovative aerodynamic channels run across the entire contour of the helmet. These channels are

integrated into the special thermoplastic poly alloy shell and direct adequate air flow into the

specially designed vent scoops. The Altitude helmet features 6 integrated vent scoops that provide

necessary ventilation to keep you comfortable when riding. Overall the Altitude features 8 total

intake/exhaust vent ports. And for those cold days, snap in the included cold weather breath box.

The unique aerodynamic visor features a locking top center mount that holds the visor in place and

prevents unwanted visor movement.

FIT:

The Altitude was designed with two key fit metrics in mind: Rider fit & Goggle fit. First we created

a custom interior EPS, matched with a premium removable liner. The Altitude is available in 9 sizes

from Youth Small to Adult 2XL. These 9 sizes are carefully designed across 3 outer shell molds,

when our competitors only use 2. This provides a precision fit, while minimizing overall helmet

circumference. The neck brace ready, contoured shell base provides a comfortable, yet snug feel

when putting the helmet on. When the helmet is fully in place it provides an unmatched comfort

fit that prevents unwanted excessive helmet movement. The eyeport of the Altitude helmet was

carefully crafted to fit our 509 Sinister X5 & Aviator goggles perfectly. Not only continuing, but

improving our world famous “509 helmet & goggle combo” fit. The Altitude helmet & 509 brand

goggles are two product designed to fit and perform at the highest level when used in combination.

And because fit is only as good as the overall weight, the Altitude starts at a class leading 1260g.

STYLE:

Finally, the always important STYLE FACTOR. We wanted this helmet to not only perform at the highest levels, but look good doing it. The shell

features sleek, yet aggressive lines that provide an innovative and unmatched look. Everything from the integrated front mouth vent, to the

innovative ventilation channels, to the sweeping upward kicked visor, provides a flowing and seamless transition. Last, but definitely not

least, we know you want to show off your riding talent while wearing the Altitude helmet. That’s why each Altitude comes standard with an

innovative GoPro® camera mount, that mounts securely in seconds to the top visor mount.

Sizing:
Size charts are recommendations from the manufacturer only. They are not a guarantee of a perfect fit. Each individual head is unique in both size & shape, and can alter proper fitting. The best way to get accurate fitting is to always try on a the same helmet at a local shop. Each helmet manufacturer has their own unique shell size & shape and size chart, so just because you may wear a specific helmet size in one brand, does not mean that you will wear that same helmet size in a different brand. 
1. Put the helmet on by grasping the chin strap in each hand and pulling it on over your ears until you feel the top portion of the helmet touch. If the helmet immediately feels too tight, i.e.; your head does not touch the top of the helmet, you cannot pull the helmet down over your ears, or is painful, try the next size larger.
2. Once you have found a helmet that feels comfortable and snug, you must assure that it is not too loose. To do so, with the chin strap securely fastened (see chin strap diagram) grasp the helmet chin bar firmly with one hand and try to move the helmet from side to side and up and down. If the helmet slides on your skin and hair, it is too large. If your scalp and skin want to move with the helmet, the fit is snug.
3. Finally, while still grasping the chin bar, try to rotate the helmet as far down and forward as possible then as far backward as possible. If the helmet feels as if it might slide off in either direction, the helmet is either too big or the chin strap was not securely fastened. This manufacturer has a wide range of helmet sizes, but if for whatever reason you cannot find a helmet in this brand to fit your head size or shape securely, look into another brand.

PLEASE NOTE: Our listing is size & color specific. The specific size & color is detailed in the listing. We are providing the manufacturer's recommended size chart for your convenience for fit. If the specific size in this listing may not be the best fit for you, please review our other listings for a size that may be of better fit.
