The BlackRapid ProtectR Security Sleeve (Regular) is a simple way to have some peace of mind when shooting in less than hospitable terrain. The ProtectR features a 1.5 mm steel cable inside a 16 oz thermoset polymer fabric sleeve, which wraps around any BlackRapid camera strap to provide an extra degree of security when shooting in situations that demand this level of caution. The steel cables will prevent the cutting or slicing of your camera strap while you are focusing on getting that important shot.In addition to their strength, the white-coated cables can be seen through their sleeve to deter anyone even thinking about a quick score. The ProtectR comes in two sizes for a perfect fit. ProtectR - Regular is 17" (43.2 cm) and the ProtectR - Long is 21.5" (54.6 cm), for those who wear their straps extended a bit longer. Both ProtectR Security Sleeves are 2" wide and quality made by BlackRapid. When getting the best shot is all you should be focusing on, it"s good to know that someone"s got your back.
