Lightweight In-Mold Construction – Low profile In-Mold designs combine a polycarbonate shell with EPS liner to provide superior impact protection and extreme light weight.

Zonal Koroyd® Coverage – For lightweight, energy-absorbing and ventilated impact protection. Koroyd® provides superior impact absorption, design flexibility, and ventilation when compared to materials traditionally used in helmet construction. By utilizing crumple-zone cylinders that crush uniformly on impact, Koroyd® manages energy more efficiently with less volume than any other protection material on the market. Unlike traditional protection materials, Koroyd® cylinders absorb and convert more kinetic energy, while increasing airflow and reducing overall weight. Not all helmets are created equal.

8 Fixed Vents

AirEvac™ Ventilation – AirEvac drives the warm air away from the goggle through external vents and internal channels in the EPS liner.

Self-Adjusting Lifestyle Fit System – Elastic in rear of liner adjusts to a range of head sizes.

Removable Snapfit SL Ear Pads – Smith earpads, with their inner surface of technical materials, provide a comfortable seal from the wind and weather on even the stormiest days. For a warm spring day, remove the earpads entirely to reduce weight and maximize cooling. All earpads are fully removable and machine washable.

Smith MAG™ Interchangeable Lens Change System – Dual locking mechanisms and 8 magnetic contact points enable speedy and secure lens changing to get your optics swapped and you back out on the hill faster. A simple push of a lever on either side of the lens releases it for swapping as the light and conditions change.

BirdsEye Vision™ – Clarifies not just your line, but the riders in your periphery. The 4D MAG has a 25% increase of overall field of view compared to Smith's I/O MAG. Utilizing Smith's new BirdsEye Vision™, you can now see more than ever before.

ChromaPop™ Lens Technology – Through Smith's proprietary ChromaPop™ lens technology, we help you see detail and color beyond normal capabilities. ChromaPop™ filters two specific wavelengths of light that cause color confusion. By doing this the lens delivers greater definition, more natural color, and unmatched clarity to allow you to see more detail.

TLT (Tapered Lens Technology) – Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an object's true size or position. Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the outer edges. Light waves are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection.

5X™ Anti-Fog Inner Lens – The most advanced anti-fog lens ever created, engineered to provide over five times the absorptive properties of anything on the market.

Two Lenses Included – Bright light and low light ChromaPop™ performance tints.

AirEvac™ Integration Technology – Smith's AirEvac ventilation Systems generate maximum airflow and ensure that warm air that causes fogging flows out of the goggles. The warm air can exit at the top of the goggles and make its way through the helmet's AirEvac system.

Ultra-Wide Silicone Backed Strap

QuickFit Strap Adjustment System – Lets you find the right fit fast.
