If you’re traveling by water, or into water sports (such as kayaking, sailing and SUPing), you know the value of having sunglasses with polarized lenses.  But it’s hard to find those ideal sunglasses that will both keep your water experience squint-free and not get lost below the waves should you drop them. The Revo Headway sunglasses meet both criteria.

The Headway uses Revo’s Crystal Water lenses, which have high-contract polarization and are highly scratch resistant. The frames, made partially from castor bean seeds (as an alternative to entirely petroleum-based nylon frames), are designed to wrap around, so that very little sunlight gets in the sides.

A flush-mounted metal spring hinge makes the fit both secure and comfortable for folks, regardless of how big or small your noggin is. In addition, the nose and stem pads are sweat and chemical resistant.

The sunglasses include a detachable leash and floating buoy. Sure, you can pop a cheap buoy onto your existing sunglasses for a similar effect, but with these sunglasses, the leash and buoy are attached with a flush-mounted spring hinge—which avoids thickening the stem pads. The only minor drawback to having the buoy attached is when you’re driving in the car. You need to flick the buoy over your shoulder to keep it from digging in your neck or back.

Does the buoy keep the sunglasses from sinking? I’ve tested these sunglasses during kayak and SUP trips in the Pacific Ocean along the California coast, and after test-dropping them in a huge tub of water, got up the courage to fling them in the ocean. And here they are, sitting on my desk.
