Full Review
The Costa Tuna Alley is the go-to frame for sight fishing guides and serious inshore anglers. The large wraparound design eliminates peripheral light leaks that cheaper frames allow, and the 580G glass lenses cut glare better than anything short of a periscope. If you spend your time poling flats looking for tailing fish, these are the glasses that will show you what you are looking for. The fit runs large, which is perfect for bigger faces but can overwhelm smaller features.
