Goggles are a very subjective product. Meaning there are numerous variables that affect performance: head size/shape, helmet, body temperature, etc. One guys favorite goggle can be another mans worst. So the number one area of importance is fit. If a goggle doesn't fit your head shape or your helmet, switch brands. A goggle that doesn't seal 100% against your face will cause issues. Every time you breath, that warm breath (moisture) will enter directly inside the goggle. Fog is a very simple thing and it happens for 1 reason: Moisture. To eliminate fogging issues, you need to first identify where moisture is entering into the goggle. Once identified, take action to correct it. Things like ensuring a good seal, proper body layering to prevent overheating, not dropping them in the snow, etc, etc all go along ways in preventing fogging.
As for mirror finishes, they are inherently more susceptible to scratching than non-mirrored. However they should certainly last longer than some have stated here.
So let me ask, of the people that have stated displeasure with our goggles, how many have taken advantage of our customer service and warranty policies? We pride ourselves on providing the best warranties and customer service in the business, so we welcome your call (1-877-743-3509) anytime you have an issue. Through simple support and education we can fix the overwhelming majority of customer issues. But that all starts with a customer service call. And you will find we do whatever it takes to make EVERY customer 100% satisfied.
That being said, we continually are working to improve our products. So we welcome both good and bad feedback. I can tell you, we have some VERY cool goggle innovations coming out for next season. Some we've been working on for a number of years and all combined, more goggle advancements that we've EVER released in our history. With key emphasis on improving functionality and durability. Stay tuned!
As for the statement that 509 is nothing more than "marketing hype", I would like to point out how little 509 as a company advertises. The vast majority is word of mouth, while we focus on our dealer & customer support on the backend. We participate in very little paid print or web marketing.
