Attack MTB = Large field-of-vision

When it comes to sunglasses for road and mountain biking, optical clarity is tops. A close second for me is unobstructed vision. I’m a semi-rimless fan because, in my opinion, adding anything blocking your vision is just plain stupid. I mean, obstacles are coming your way in a hurry out there, so why give yourself a handicap due to your sunglass frames?

I’ve been happily using the Smith Attack Max sunglasses all year, but have found the Attack MTB’s to be equally-awesome with an extra dose of lens protection and style that lends itself to a more dirt-focused crowd. Certainly, the Attack MTB’s can be used for road and gravel riding without worry. Well, I did initially worry that the lower frame would inhibit vision, but in my testing, it doesn’t block any critical vision on the road or dirt.

Really, the top and bottom frames are primarily built for lens protection. There may be a little bit of airflow afforded by the brow piece, but primarily, those areas are there to protect the lens in a crash, or banging around in the back of the car.

The low-light Amber lens is fantastic for cloudy days or early mornings. I found myself with those lenses more often than not because the Attack MTB’s have become my dawn patrol sunglasses of choice. With those lenses, early-morning clarity is excellent, with a wide field-of-vision. They are ChromaPop, so colors pop really nicely.

With the green mirror lenses, I found the Attack MTB’s to be awesome for mid-day adventures. In general, you want to match your lens tint to your surroundings (blue is for water, green is for lush green areas, red is for deserts, etc.). We had quite the wet spring, so the green tint was awesome during the late spring months with grass and foliage galore here in Utah.

To further test the capabilities of the Attack MTB’s, I wore them on gravel and road rides, but I also used them extensively for trail running. Under all those uses, they perform superbly — with great optical clarity and field-of-vision.

The nose piece is adjustable based on the shape of your schnoz. The Megol rubber does a great job of keeping things in place, but I feel like the temple tips could be a little grippier. Everything is holding up well with little sign of use in spite of having them banging around in the back of the Pathfinder all season. On humid mornings, they do tend to fog up a little more than I’d like and do require a good cleaning before starting again. They do clear, but it takes a little longer than I’m comfortable with (so I usually just cleaned them after long climbs, which is where it occurred most often).

The Good

• Field-of-vision is outstanding
• Lens changes are a cinch
• Optical quality is on par with the best on the market
• Large lenses offer tons of protection
• Adjustable nose piece accommodates different nose shapes

The Bad

• Temple tips could be a little grippier (but they stay in place nicely)
• They do tend to fog up

If you’re on the hunt for a new pair of MTB shades that have a huge field-of-vision and killer optics, there Smith Attack MTB’s are an obvious choice. Lens swaps are easy with MAG, so you can actually swap things around on a whim.
