Beth Van Hookwrote a review of Giro Basis Goggle on March 7, 2013
Overall the Giro is a good goggle, ordered with the Amber Scarlet lens for bright sun to partly cloudy out west and it did fine. This particular lens is NOT good for overcast flat light! Peripheral visibility is really good as well.
I have a narrow angular face, tried this in the store and thought it fit well. However after receiving it from backcountry at a very affordable price, I didn't think it fit as well. It seemed to be more curved than I remembered (narrow profile, doesn't stick out past the side of your face). My husband and I switched goggles and he likes their fit more than I do. His goggles are the Smith I/O and I prefer their fit much more - they seem to be a bit flatter across and sit high enough to not pinch my nose.
Overall for the price, these are good goggles.
