the new dragons don't fit well with helmets. The new anon that is the big fishbowl style (can't remember the name) fits real well, not as big on the top part, so unless your looking straight up the prefirial is great. If i didn't get new goggles right before i tried them on it would have went with them.
What about the best peripherals period? I can't fucking stand goggles, so if i you guys can find me a suitable pair, i'll pop a clear lens in and owe you my everlasting love & devotion.
i personally dont have an issue with blocked periphery but my friend does and he swears by the adidas yodai, so much so he has now got 2 pairs. it is has a fairly un-interrupted periphery but aren't as bug eyed as some of the others (APX for example) so would fit under a helmet better. http://www.adidas.com/Eyewear/content/us/products/10216/yodai
The over sized frame and better field of vision is definitly a trend in the goggle industry right now and should be. I love it, but the draw back on the progression is fit with helmets. Goggle companies will be increasingly designing and merchandising goggles and helmets together so it will improve. My website, www.actionsportoptics.com carries the oversized frame from Anon ( the Comrade ), the Dragon APX, andthe Spy Platoon, and I would say that while the Dragon APX probably pushed the envelope the most on progression, the Anon and Spy fit better with helmets.
