Opticron 45.5mm BGA Binocular Rainguard

The one-piece design is so much easier than fiddling with two separate caps when I'm out birding in the rain. It fits snugly over the eyepieces and does exactly what it's supposed to, keeping the lenses dry and dust-free.

I was tired of my binoculars getting spotted in light drizzle, so this one-piece eyepiece cap is a perfect fix. The universal fit is snug and clicks on securely. It’s a simple accessory that finally does the job.

Finally, a rain guard that actually stays on when I'm hiking with the binocs around my neck. It locks into place over the 45.5mm eyepieces without any wobble, and the one-piece design means no fumbling to find a separate cap.
