I LOVE these! I really do... but problem is; I am an instructor, and I am always putting these over my eyes, then taking them off, repeat the whole evening (yes, I do the evening lessons, mostly, some daytime). I find that my head is a tad too small for the straps, and becuase of the Large (but cute) logo, I can't adjust them any tighter. That's my only gripe with these goggles. Otherwise, they're awesome. Night or day, and both lenses are adequate for my needs.
