Constructed of high quality 3mm thick neoprene/nylon laminate, the Standard Scopecoat is designed to fit scopes with standard or low turrets, safeguarding your optics from dust, dirt, dings, scratches and moisture. This slim fit cover is perfect for the field. It is water resistant and draws moisture and condensation away from your scope and it is machine washable. Note: The "perfect fit" is a matter of personal preference, ranging between a relaxed fit to a more form-fitted one. Cover can stretch 1-1.5" beyond stated length.
