These goggles are great, never had a problem with them fogging up or anything. They fit my face perfectly, and while they are fairly large, they aren't so big that they make look like a space alien. The field of vision is fantastic, and the mirrored lens offers crisp and clear vision in bright conditions, yet light enough so you can see even at night. I've taken a few nasty spills where they've flown off my head, and each time they survived unscathed. All in all, solid pair of goggles.
