I'm very picky about goggles. It's probably because I already have poor vision and the weather conditions in Colorado change without warning. Sick of awkwardly stuffing an extra pair in my pants pocket, I opted for the Scott LCG.
The goggle comes with two lenses (one for flat light and one for bluebird days) and a compact case for the lens you're not using. With just the slide of a switch, I'm able to change the lens with my gloves on and goggles still strapped to my helmet. They are by far the easiest lens-changing goggles I've used.
My favorite thing about the LCG is Scott's Fits System, which lets me fine tune how the lower frame fits around my nose. For me this is a godsend: I was cursed with a hideous bump on my nose right where most goggle rest, causing extra air and fog to impair my vision. Because a nose job is not in my budget—nor do I desire one—I'm glad Scott was able to help me out.
Note: The LCG is part of Scott's 2013-14 lineup and won't be on shelves until late summer or early fall.
