It goes from 0-4, considering its VLT (visible light transmission).Ġ is clear, and 4 allows less than 10% of the visible light through at its darkest, this is a dark lens. The lens in this pair of goggles is the new REACTIV 0-4 high contrast lens. When the clouds part, these photosensitive lenses darken right up. This also makes the goggle great for dawn patrols that leave you atop a line at daybreak when you still need to drop in- work awaits. The lens doesn’t darken considerably in mid-winter low-angle light and in cloudy conditions, so it is still excellent for low-light conditions. As someone who wants to keep lens options to a minimum, this has been a great feature. Call these “transition” lenses they darken or lighten, depending on UV exposure. Julbo is known for its high-quality photochromatic lenses. The Aerospace has me covered for most light conditions I’m likely to encounter. With my assortment of glasses hauled along for most ski tours, I’m a single-lens user when considering goggle lens options. I understand that many goggle models can interchange lenses depending on light conditions, including clear lenses for low light. I usually accept a lack of flexibility regarding available (and type of) daylight and having a specific goggle lens for the day’s light. This means I often bring two sets of glasses: one for sunny conditions and another for dawn patrol starts or potential post-sunset returns. The REACTIVE 0-4 High Contrast LensĪs an eyeglasses wearer, I also think about available daylight. This image, provided by Julbo, shows the Reactive 0-4 High Contrast lens in low light conditions. Opening up the SuperFlow System is possible for descents, but know you’ll feel brisk air flowing through the lens. I wear the aforementioned prescription sunglasses in most conditions while descending unless it’s spitting moisture in that event, I wear goggles. Yet, I know many others who, 100 percent of the time, wear goggles while descending, no matter the weather. DescentsĪ goggle should serve the basic function of eye protection in inclement weather. These goggles are as good as I’ve seen regarding lens fog prevention. If you insist on wearing goggles on the up, the Julbo Aerospace should be considered part of your eyewear quiver. In my experience, the extra ventilation of a mesh ball cap helps with the Aerospace’s anti-fogging properties. I often skin in a mesh ball cap with a buff over the cap and a fleece hoody (with hood deployed) if extra cold. Wearing a thicker nordic style hat traps more heat which may cause more potential fogging. One thing to consider, too, when donning the Julbo Aerospace goggles, is what type of hat you’ve got atop your head. This image shows the Super Flow System opened and the “peak” fixed atop the lens. However, I almost always bring goggles in the pack, as I’ve been burned too many times historically with a clear and sunny forecast only to be duped into complacency and absent goggles when the dumpage ensued. If it is dumping, I wear goggles on the descent. In other words, I use goggles purely for function and not style. While ski touring, I wear prescription sunglasses (review pending) and use goggles sparingly. Some notes before we proceed: I wear prescription glasses and have shied away from contacts. Primarily, I’m talking about the propensity for lenses to fog up and the changing nature of light conditions in the mountains. In the backcountry, goggles can come up against some deal breakers. (They also serve as the unofficial “hey, I’m a skier/rider” signage dangling from a rearview mirror in any town close to snow and some vertical relief.) The past few years have seen wide full-view lenses provide near windshield-like coverage. Besides looking rad and cyborg-like, they provide high-value function when the snow blows sideways, and good vis is required. We tested the new lens in Julbo’s Aerospace, a goggle designed to mitigate fogging with a built-in vent system. Julbo has introduced a photochromatic lens in the Reactiv 0-4 High Contrast that offers a single-lens option for changing light conditions. The lens is available in several other Julbo models. The Julbo Aerospace offers a ventilation system to help prevent fogging and the option for a 0-4 photochromatic high contrast lens.
