superb handling rainguard .
fantastic quality rainguard thats vastly superior to the one supplied with my new Opticron discovery 8x50 binoculars . Even though the stock item does the job its kinda difficult to remove with it being tight fitting rubber , but this deluxe one fits like a dream and is very speedy to remove when you chance upon that elusive sighting . I'd advise anyone buying this model of binoculars to also order this rainguard (45.5mm) at the same time as it makes such a massive difference to the handling . The other thing worth noting is this size also fits the Opticron discovery 8x42's as well , looks like ill be ordering a second one for them now then lol .

A V good product
I have just purchased a pair of these 37mm Opticron BGA binocular rain-guards for a pair of classic Carl Zeiss 10 x 42B (1980's) that I have just purchased second hand. They fit extremely snuggly over the lenses and also attach very easily on the left side to the neck strap. As long as you measure your lens correctly, you cannot go wrong with this robust, stylish product which is also, at under £10 very good value. Andrew Bruce, Dumfries & Galloway, Scotland.

Good enough for non-Opticron binocular
Bought these for my Olympus 10x50 DPS bins and they work reasonably well, much better than the single caps I had originally. Can't lose them as they fit on the neck strap, and they pop off in one when needed, so they do the job nicely, though not a "perfect" fit.

Excellent product at a good price
I recently bought a pair of Nikon Sporter 8x42 binoculars (another excellent product by the way). They come only with single caps for the tops of the lenses. Though they're rainproof I don't want rain drops on the viewing lenses so I looked for a rainguard. The opticron one fits the bill exactly. What's more, the join between the two sides bends so that you don't have that annoying business of always having to adjust the width of your bins whenever you take the rainguard on or off. It's a sturdy plastic which will take knocks -- I sometimes carry a camera as well as bins and though I have the former on a shortened strap and the latter on a longer harness, I do worry about the bottom of the camera coming into contact with the glass of the binoculars. I highly recommend these -- and they come in different diameters so you can buy the one which fits your particular model (just remember to measure it carefully!)

Good secure fit and functions well.
This product does what it says it will. Fits nicely on the strap and securely cups the eyepieces. Looks good and allows you to keep the binoculars out and ready for use without worrying about getting dust on the eyepiece lens. Works great when carrying them and they are quickly slipped off ready for use.

Awesome product
The cap appears to be very sturdy and of good quality. At the same time, it bends smoothly, along the connecting strip. It takes slight effort to put up on my binoculars, i.e. it does just clip on and one needs to bend the soft rubber in, but it snaps off easily when needed. It then hangs without problem from the strap. All in all, a very good product to protect the lens from dust or dirt while keeping one's binoculars at hand.

Good value
Good value although fairly cheap plastic. Fits well on Leica binoculars.
