Take it to the top: Scorpion EXO-AT950 Teton Modular Helmet

Helmet design has come a long way since the days of the pudding bucket. The new Scorpion EXO-AT950 Teton helmet is vivid proof of that.

There is a lot going on with this helmet—it is clearly the result of a lot of careful development, thoughtful design and in-use proving by folks experienced with helmet use in a variety of conditions.

As a helmet designed to be capable of handling cold-weather sports, yet with the versatility to handle all-round applications as well, the Teton has capabilities for comfort and function across a much broader range of ambient temperatures than many other helmets.

While it includes snow-specific features, the Teton proves to be a very comfy and capable helmet for road-going motorcycling, ATV and UTV use, even in warm temps.

Scorpion EXO-AT950 Teton Modular Helmet test

First, let’s take a look at the AT950’s overall credentials. The shell is Advanced LG® Polycarbonate with dual-density expanded polystyrene (EPS) impact attenuating inner lining.

It is equipped with an over-sized eyeport that is extra wide to optimize peripheral vision and downward vision and it is designed to accommodate most off-road goggles. It is available in neon-bright fluorescent colors with reflective piping in the bottom edge of the helmet’s comfort liner for improved visibility to other drivers in low-light conditions.

It comes with a fog-resistant dual-pane face shield that exceeds VESC-8 standards as well as an integral drop-down amber sun visor. To further manage face shield fogging, the Teton includes a removable breath box.

The face shield is one area that shows remarkable attention to detail, not only in its fog-fighting dual pane lens and ample viewing area, but in a little touch like a lift tab on both the right and left bottom edges of the shield. So many helmet shields have only one lift tab and that is either on the left lower edge or in some designs in the midpoint. It’s a nice touch and illustrates how sweating the details can add value and function.

The Teton is a modular helmet that can quickly shed the aerodynamically designed peak (with a simple tool like a coin—a nickel works perfectly) to shift from snow or adventure use to a street motorcycle helmet. Doing so has a second step; the installation of the side covers that mount over the chin bar/face shield hinge point. The side covers come packed in a bag and the peak is installed as the helmet is delivered.

Packed with the side covers are two small translucent plastic washers with three small nubs molded in that match three notches in the hefty metal boss that the visor screws thread into. Those washers must be installed after the side covers are put in position and then the visor screws can be tightened down and the conversion is done.

Shedding the peak is a good idea if you plan motorcycle use at sustained Interstate highway speeds. The peak, while vented to reduce lift and buffeting still can catch some air under the right circumstances and cause some buffeting. That was not a problem at more common off-road and snow-use speeds.

The face piece/chin bar unlocks with a single toggle-type release in the bottom of the mid-point of the chin bar. The action is smooth and positive. The face piece lifts and locks in place in the up position with a firm detent position and pulls down and locks back into place easily and positively.

The chin bar has a sophisticated dual-channel ventilation system; one part has a closable vent to help channel air in and out of the breath box. That channel’s shutter is on the inside of the chin bar in the breath box. The other is the more conventional closable air inlet shutter on the outside of the mid-point of the chin bar. That air flows into the face piece via three outlets atop the chin bar.

Taken together, the vents act to both ventilate the interior and to de-fog the inboard surface of the face shield. Both shutters can be operated with gloves on. Again, somebody put a lot of time into this part of the helmet.

Ventilation to the rest of the helmet is provided by a wide air scoop on the crown that toggles to open and close, easily operated with gloves on and exhaust vents out the back. The comfort liner is crafted with KwikWick II anti-microbial fabric and it is removable and washable. The vents didn’t create any whistling or buzzing noises, even at highway speed, whether open or closed.

The breath box functioned well, but with the dual pane face shield and chin bar vent system, I wondered if the breath box was necessary as I did a day of motorcycle riding that started out with temps in the mid-forties and rose into the fifties. So, after a while, I removed the breath box, which is secured by three tabs and two snaps. Even with the breath box removed no face shield fogging occurred.

When the sun came out, the internal sun shield worked well, deploying easily with the slide control on the left side of the helmet’s crown. The tint is effective in easing the eyes and the shield didn’t create any glare, even when the sun is low in the sky.

That’s a wrap: Scorpion Yosemite XDR Jacket

With the Teton helmet handling the all-weather protection chores up top, what comes next is gear for the torso. The Scorpion folks have dreamed up a remarkable complement to the hi-viz Teton helmet—the hi-viz neon Yosemite XDR jacket.

As is the case with the helmet, there is a lot going on with the Yosemite jacket. Yet, despite the long list of high-tech materials and features the jacket has packed into it, the thing that struck me is how thoughtful and functional the design is. As with the helmet, the jacket has been conceived by folks who have been there, done that and know what how to translate “wouldn’t it be nice if there was a jacket that could…” into “we just created a jacket that can…”

Scorpion Yosemite XDR Jacket Review

For example, the Yosemite is truly multilayered for maximum functional flexibility. There isn’t just an exterior shell with zip-out lining like most jackets. There are two internal linings that can work together or separately as conditions warrant. There is the full sleeve EverHeat thermal liner for cold temps and there is a full sleeve H2O Blok waterproof / windproof liner.

Those two elements taken together with the external textile shell crafted with 500 denier nylon main body material, with 1680 denier nylon abrasion zones make a mission-capable whole. The exterior construction is bolstered by Exo-Stitch Safety Seams with heavy bar tacking at high stress areas to prevent seam separations.

When temps get balmy, the linings can come out, the chest panel vents open up, you fold down the inner windproof panels on the chest and back; open the full-length arm vents and side torso vents, and the mesh panels give you great air inflow.

Wearing the Yosemite jacket with only a thin long-sleeve baselayer in temps in the mid-forties was very comfortable with no discernable air infiltration along the main zipper in front or at the long vent zippers along the front of the sleeves. Frankly, I had no concerns about cold air getting in along the main zipper since each of the inner linings has hook-and-loop closures on storm flaps that are incorporated into their design. In addition, the external shell has a wide, full-length storm flap with both hook and loop closures and snaps to secure it against the wind.

It was those long vent zippers on each sleeve that I suspected would prove to be a weak spot in the windproofing, because they have no external storm flap, but I was wrong.   With both inner linings in place, the sleeve zippers did not appear to allow discernable heat loss or cold air infiltration along their length. At much lower temperatures, that may be more of a possibility, but in my experience with the Yosemite product, it wasn’t a problem.

The weather isn’t the only thing that the Yosemite is designed to protect against. Impact protection is provided at the elbows and shoulders with SAS-TEC CE certified armor. The back of the jacket comes equipped with a PE foam back pad in the back protector pocket that can be upgraded to Level 2 SAS-TEC protector.

The sleeves are equipped with a pair of cinch straps above and below the elbow protectors that can be snugged up to help keep them in place over the joints they are to protect.

Another quality that reflects the experience of the Yosemite’s design team is the cargo capacity built in. The Yosemite has two large box-style cargo pockets on lower front with hook-and-loop closures on the flaps, two zipper-closure chest pockets and one very large cargo pocket across the rear, and one internal waterproof pocket in the liner. You may say there’s nothing new about lots of pockets on a jacket like this, but in this case the magic is in the size of them—they are all pretty large, (the rear pocket is 15” wide, X 8” deep by 2” from front to back).

The front cargo pockets are 7 ½” wide X 6” deep X 1 ½” and the chest pockets are 5” X 9”. The box pocket flaps have very handy—as in easy to grab and use with heavy gloves on—large rubber tabs to make it easy to get a grip on them and open them.

I’m a fan of hi-viz colors and reflective materials on gear for powersports. Being visible in all lighting conditions is a vital strategy for personal safety whether on or off-road, summer or winter, you name it. Both the Teton helmet and the Yosemite jacket bring fluorescent colors and retro-reflective materials to bear as part of the suite of protective design elements.

In the case of the Yosemite jacket, its durable textile outer shell offers abrasion protection, the CE armor at elbows and shoulders along with the back pad provide impact attenuation for key body parts and the color/reflective combination increases “conspicuity” to help prevent problems with other drivers.

Taken together, the EXO AT950 Teton modular helmet and the Yosemite XDR jacket form a functional, protective gear set that can adapt to nearly any weather and riding condition you might want to be out in.
