I have a pair of cycling-specific sunglasses and they work great for cycling. But they look like cycling sunglasses and that means off the bike, I don't want to wear them. I have tried casual sunglasses so I have something to wear when I'm not riding, but they've all been "too casual." What I mean by that is that there were no performance features built in. So if I wanted to hike or go for a casual ride, they'd move around a lot.
The Spinair 57 combines a casual frame style but adds the soft rubber nose pad and temples to make sure they stay secure should you want to move around while wearing them. This has made them my go-to pair of shades for when I know I'm going to be active but I will still want to wear them once I'm done being active. The weight at 32 grams is not the lightest, but I appreciate that it adds to the high-quality feel. And they definitely are not heavy. Of course, no matter how well a pair of sunglasses may fit, I wouldn't wear them if the lenses were not up to par. These provide crystal clear optics. Overall an awesome pair of shades that I highly recommend as do-it-all staple for your collection.
