The Scopecoat Scope Cover - Large 12.5"x50mm Black from Scopecoat delivers a slim, field-ready shield for optics, measuring 12.5 inches in length with a 50 millimeter objective, designed to fit scopes with standard or low turrets while maintaining a snug, protective profile. This neoprene/nylon laminate cover safeguards against dust, dirt, dings, scratches, and moisture, yet remains breathable to draw moisture away from your optic, helping to preserve clarity in varied conditions. When selecting a size, measure the overall length of your scope in inches and the objective lens in millimeters, and note that standard Scopecoat cylindrical covers stretch roughly 1 to 1.5 inches beyond the stated size for a flexible fit, so you can choose a relaxed or snug option. Although not completely waterproof, the cover offers high water resistance and can be treated with a spray-on water repellent following manufacturer instructions for added protection in rain or wet snow. For maintenance, clean with warm water and mild detergent, avoid bleach or fabric softener, air dry after turning inside-out for about 12 hours, and refrain from folding to prevent indentations or damage.
