Opticron Rainguard for 40mm Binoculars

A protective rainguard (eyepiece cover) for binoculars with a 40mm internal barrel diameter. Keeps rain, dust, and debris off your eyepiece lenses when the binoculars are slung around your neck.

Quick to fit and remove, with a tethered design that stays attached to the binoculars. A small accessory that makes a real difference to lens cleanliness during wet field days.
