Opticron 31020 43mm BGA Binocular Rainguard Black

Got this for an expensive Nikon set. I like the way the cover can fit the glasses no matter how far apart or close the lenses are. All in all, a pretty good design.

Have a fairly good pair of binoculars optically, but the lens covers that came with these glasses were poor, at best. The covers were split and lost in no time, leaving the lenses unprotected. Luckily, these covers were located and purchased, and they do provide excellent fit and protection. They not only protect the delicate lens surfaces from rain, but also from dirt, dust, and fingerprints. When installing, just remember to attach them - with their loop - to the binocular strap so they are themselves not discarded or lost. On initial observation, these seem expensive for what they are, but their quality, fit, and provided protection are nothing less than superb. Keep in mind, if the binoculars were worth purchasing, they are worth protecting. In that vein, this is well worth the asking price. One last thing: make sure you measure the outer diameter of the eyepiece ( with a millimeter ruler ), containing the lens and the housing. A guess here could result in guards that are too large to protect well or, worse, too small to be useable. That being said, these deserve a ' 10 ', or 5 full stars.

This cover fits my Nikon binoculars perfectly. It is durable and strong and works very well. It stays in place and does not work it’s way off of the binos. It attaches very securely to the neck strap, no worries about losing it. Very pleased with this item.

Lost rainguard for Nikon binoculars. This attaches more securely and fits more tightly, may loosen with use.

Quality material and it stays.

The cover fits ok, it's just the condition of it. This is SUPPOSED to be NEW, but it must have been a return, unless it comes from the factory with gouges & scratches! I didn't have my glasses on when I got it a few days ago, didn't even notice. Grabbed them to bring outside this morning and saw the gouge and thought WTF? They stay in the case, no way it got scratched in the case all by itself. Next time I'll scrutinize it a bit better. Quality control sucks nowadays!

Perfect fit.

If you do birding or hunting or target shooting, after a while you find out that there are only two good brands of binoculars in the sub $1,000 range - Nikon with its Monarch 5 and 7 series and Vortex with equivalent series. They come with 30+mm objective lenses for better portability and $40+mm for the ultimate experience. Nikon has terrible eye caps and Vortex - extremely stiff mechanics. Optics is great on both. So I bought these caps to replace my terrible Nikon front caps. Also tried the excellent Vortex ones - both sizes, but they don't work size-wize - Vortex doesn't want to give freebies to Nikon.These caps work. They stay on the eye pieces unlike the Nikon ones. They are thin cheap plastic and have a couple sharp edges. Ultimately I went with another no-name brand from Amazon made from thick rubber. I kept these as well just in case. Glad to find two working solutions after 15 years of suffering.
