The Good: Articulating outrigger for goggle strap to help with different helmet shapes, bright vibrant colors, roll-off kit included, Goggle foam excelled at keeping dust and small particles outside. Made in the USA.
The Bad: Slightly long goggle strap, Lack of tear off posts on roll-off canisters, Anti fog lens wasn't as effective as I would have liked.
What you get: The current price of the Smith Intake's I used is $65. For your money you get a pair of Intake Sweat-X's (coming in 4 colorways) a cloth baggy to hold them, and a roll off system.
The goggles themselves are well made, multi-layered foam, on a outrigger style frame.
An articulating outrigger system - This allows the outrigger angle to change. This was quite helpful with different helmet shapes. In the past I've run into outrigger frames that just allow the strap to pull wrong on certain helmets and create and uneven seal along your face. The articulating frame helped with this on the few different helmets that I tried with these.
The roll-off system - Most goggles you buy nowadays come with a soft baggy and possibly a few tears offs or another lens. These Smith's come with an roll-off system that is interchangeable with the lens (the tear off post's on the lens are removable). So instead of having to have separate roll-off systems on each lens and having to buy all new systems when the lens gets scratched, you can now just put the system on different lenses of your choice: clear or available tints. The instructions are slightly vague on how to put the system together but the process isn't overly complicated.
My one complaint with the system is the lack of tear off posts on the outside of the roll-off the canisters. The few races (mostly mud and sand) that I've used a roll-off system, I preferred having a few tear offs on top of the roll-off system so during the first few corners of a race when you're getting the most "pelted" with roost, you can clean off your whole field of vision before switching over to the slide on the roll-offs that only clean a portion of the lens. I also recommend putting these together (especially the first time) at home and out of the dust and grime of track conditions.
The Frame - The goggle frame itself has vents at the top which can be opened to channel air more directly to the top of your head, The foam itself is of good quality, especially around the air vents. Having ridden with these on a few windy and dusty days the foam was exceptional at keeping dust and small particles out.
Negatives: This is a small complaint about the strap that may or may not bother some, I found the strap to "Stretch" out quite a bit the first few times I rode with them and had to adjust the strap quite a bit at first to keep it tight. I rode on a few "wet" mornings where the anti-fog lens included didn't work quite as well as I expected (while riding at speed wasn't a problem the moment i stopped... and I mean as soon as I stopped, they would fog up a bit). As I mentioned above I would have greatly preferred tear off posts on the roll-off canisters.
Conclusion: The great quality of the goggles makes up well for the little complaints I have. As a stand alone goggle I would give it a slightly higher rating but the roll-off system leaves me wanting a little more.
