What a great pair of goggles. Not exactly sure where to begin, but overall these goggles have been fantastic so far this season. Purchased the Gunmetal/Lime version with all (3) Prizm lenses.
Simple yet very effective design. Extra wide silicone lined strap that stays put, plush face foam that wraps all the way around with no air gaps, and a very simple lens change system.
Although these are not touted as being a "Quick Change" goggle, a person would really have to struggle to NOT swap out the lenses in anything under 30 seconds. Definitely a learning curve - but once you get the process down only the Anon M2's are faster to swap.
I have been able to use the Prizm black iridium lens in everything but the most overcast/dumping conditions. When the skies open up and it is foggy/cloudy or snowing heavily, the rose Prizm lens works better than any other manufacturers low light lens - even better than Oakley's Hi-Intensity yellow. If you want a great all-purpose lens stick with the Prizm jade iridium - but these have been very hard to find.
Durability has been superb. Skied right through a tight grouping of trees, and took a few branches right across the lens. To my very happy surprise - not a scratch to be found.
Works with any helmet I tried from Smith, Giro, or K2. I did compare these head to head with the IOX, Giro Onset, Shred Stupefy, Anon M2, Electric EG3, Electic EG2, and Smith IO7. No other goggle has the same or better view when looking up, down or out peripheral.
If you see them in stock, don't hesitate - buy a pair, you won't be sorry.
