Opticron Rainguard for 37mm Compact Binoculars

A protective rainguard (eyepiece cover) for compact binoculars with a 37mm internal barrel diameter. Shields eyepiece lenses from rain, dust, and debris when the binoculars are hanging around your neck between observations.

Soft, flexible material slides on and off easily. Stays tethered to the binoculars so it will not get lost in the field. An inexpensive way to keep your eyepieces clean and scratch-free.
