Fits Leica 8x32 Ultravid
I couldn't find Leica supplied replacements so tried these. They fit ok although they are a bit tight - I'd get the next size up if I need to buy them again. A bit pricey.
User
Fit well but quite expensive
Bought to replace lens caps on an old pair of binoculars. Fit well as long as you measure properly and the loops keep them in place when removed. A bit expensive for bits of rubber but good quality.
User
good replacement, don't lose again...
straight replacement for original. Make sure to fix it in some way as it'll come off and get lost (again and again). I used some double sized sticky tape.

Replacement lens covers

Not great but functional
They kinda fit sorta. Not convinced that they'll stay on.

Good kit
These were as described. Good value and easy to use. They are better than the covera supped with the binoculars
User
Good quality better than the originals that came with my binoculars.
These are much better than the lens covers that came with my Nikon Prostaff S3's, the size you need for the S3's are 50-52mm they fit perfectly.

bouchon de protection pour jumelles
Le produit correspond à ce que je voulais pour protéger efficacement l'objectif de mes jumelles.Le caoutchouc est à la fois souple pour s'adapter au diamètre extérieur des objectifs même si ceux ci sont d'un diamètre légèrement supérieur à celui de l'intérieur du bouchon et en même temps robuste, l'épaisseur de celui ci étant bien dimensionnée.Conseil au vendeur: annoncer précisément le diamètre précis (en millimètres) de l'intérieur du bouchon.

A very tight 42mm
A very tight 42mm, warm them before fitting and they will slide on easier. No fear of them falling off in cold weather.

Cumplen su función
Para mis Zeiss Terra ED 10x42 perfectos. Algo caros para ser dos trozos de goma pero bien.
