Featuring UPF 50+ protection against damaging UV rays, the Simms SolarFlex Half-Finger SunGlove keeps our hands from getting fried while keeping our fingers free to tie knots and maintain feel of our fly line. Lightweight overlays add durability to high-wear areas while the extended cuffs keep our wrists and hands protected from the sun when we're working high-mountain streams for rainbows and stalking saltwater flats for stripers and bonefish.
