The Huskemaw Optics scopecoat is constructed of high quality 5mm thick neoprene laminated with nylon. It's simple design safeguards any kind of scope from dings and scratches, dust, dirt and moisture. Neoprene has a 5% moisture absorbency, which pulls moisture away from the scope and helps protect it from rust and corrosion. Built by Scopecoat for Huskemaw Optics.
