ScopeCoat EOTech Holographic Sight Protectors / Protective Covers are constructed of the highest quality 2mm Neoprene laminated with special moisture absorbing nylon lining on the inside and out.

The Neoprene has a 5% moisture absorbency which takes moisture (condensation and sweating) away from the scope and helps protect it from rust and corrosion while the nylon shields against the elements.
