Product Reviews I've used these Native Spring sunglasses for a few months now. I've worn them for training and half marathon races several times.
They are extremely light weight and don't bounce at all. I use them only for sports activities as they are not exactly fitting for a night out on the town. I needed something that functions this well when my runs last for several hours and had to put the fashion-conscious side of my brain aside.
Though they vent better than most sports sunglasses, they will fog up under extreme conditions both cold and hot. There have been a couple of times when I've had to take them off in order to let them vent and they clear up fairly quickly and are ready to be put back on.
Other than the occasional fogging up, I pretty much forget these are on my face and the help with the bright conditions and glare.
I would highly recommend them.
