Built to perform in any cold weather fly fishing environment, the Simms ExStream Flex Gloves can be relied on to keep anglers on the water longer. The advanced Polartec Powershield Pro fleece material sheds water, stretches for mobility, wicks moisture and insulates against cold and wind. For added insurance against icy water, a DWR treatment creates a water-resistant barrier. Tough suede overlays ensure a solid grip in wet conditions while the finger openings allow dexterity when tying knots and managing line. Winter fly fishing is not for the faint of heart, so the Simms ExStream Flex Gloves are built specifically to meet the challenges encountered when the mercury drops.
