40.7-42mm Binocular Rainguard/Eyepiece/Eyecup Cover/Dustguard/Eye Guard Cap Rubber Black

Stiff fit on my Bresser 8 x 40. Flexible and suitable joining piece.They appear durable and are effective for their purpose.Good value for the price and a worth investment to keep my lens protected from rain & dust.

Good quality generic product. Advice on sizing is very good.

Excellent fit for my Opticron binoculars.

I never really liked the the original rubber rain-guard covers on Swarovski 12 x 50 EL as I always found them to be too stiff; eventually over time broke off at the point were they loop onto the straps (I think this was largely because of their inflexibility which put too much stress on the rubber loops). These, in my opinion despite being far cheaper, are a better option than the original Swarovski rubber covers as they fit perfectly and have more 'give' or flexibility to them. I needed the 42-43mm size and am very happy with these, on initial impressions at least - hopefully they will last for a decent amount of time.

Put these on my Zeiss Terra ED compact 8x25sPerhaps slightly roomy on the eyepieces, but works just right for me.

Happy with product fits my binoculars

Better than the original 2 separate ones . Good quality and good price.

Not the size they claim to be....smaller....so useless!
