Familiarity: I've put it through the wringer
I am very new to the Shred line of products, and I admit that I returned these goggles the first time I purchased them. But, after some serious regret I purchased these again in the S-Duper and I am so glad that I did.
So many companies today are touting a "quick lens change" technology. I would put these up against anything from Smith, Oakley, Scott and the like. If you can't swap out these lenses in 15 seconds or less you must me on the short bus. The only goggle that is easier to change is the Anon M2.
The field of view from these goggles cannot be beat. They are a bit of an oversize fit, so you would definitely want to try these on with a helmet if you wear one. Backcountry.com did not sell any replacement lenses this year - a real bummer - but I was able to pick of a few from shredoptics.com
My only gripe is I wish the goggle strap were just a tad longer.
