I just tell myself that I need as many pairs as I have because weather conditions vary and it is always best to be prepared. Flat light? Got a goggle for that. Riding at night? Got a goggle for that. Bluebird day? Yes, I got a goggle for that too. Cloudy but not flat-light, tapering to snow flurries in the afternoon and brilliant sunshine early evening until night riding in the rain/fog? I don't have a goggle for that but if you know of one, I'll buy it!
hahaha this is so me lol. I have 6 pairs of goggles. I honestly only need 1 pair. I only ride at night. Ive only ever bought oakley goggles. For some reason other goggles i have tried just dont "feel right". Ive been looking to buy replacement lenses for my oakley splices but cant find any.
