Sunglasses are a crucial component to fly fishing, but the river has a way of exacting its pound of sunglasses, as any dedicated angler knows. The Dragon SeafarerX Polarized Sunglasses are equipped to deal with the wear and tear you'll encounter on the water thanks to a frame that floats and lenses that will resist the elements, while offering the polarized performance you need to spot fish from a distance.Coming from Dragon's Hydra Silo line, the SeafarerX is specifically designed for those who spend the majority of their time on the water, either in pursuit of freshwater trout, saltwater fish, or the best waters to stand up paddle board on. Their adaptive technology give these sunglasses the ability to adapt to the day's pursuit with a removable silicone leash that can be attached to the frame when you head to the water. And as a fail safe, the frames will float, just in case they somehow slip into the water. The anti slip rubber nose and temples keep the sunglasses firmly in place, even when wet. In addition to the polarized technology and mirrored finish, the lenses are also treated with a sealed, multi layer, dual sided hard coating that resists moisture, oil, fogging, smudges, and scratches, ensuring long lasting performance during the most demanding water based activities.
