The Scopecoat Mini 5.75"x20mm Scope Cover in Black is designed to protect your optics in the field with a slim, low-profile fit that accommodates scopes with standard or low turrets. This protective cover uses a high quality neoprene and nylon laminate to guard against dust, dirt, dings, scratches, and moisture while allowing the scope to breathe. When selecting a size, measure the overall length of your scope in inches and the objective lens in millimeters, then choose a cover that provides a relaxed or snug fit, noting that standard cylindrical Scopecoat covers can stretch about 1 to 1.5 inches beyond the stated size for a custom fit. While not completely waterproof, the Mini 20 offers strong water resistance and helps shed moisture, and you can temporarily enhance water repellency by applying a spray-on treatment following manufacturer instructions. After use, if soil is present, machine wash in warm water with mild detergent, avoid bleach and fabric softener, air dry inside out for about 12 hours, and resist folding to prevent creases that could affect performance.
