These covers also fit several binoculars / monoculars with objective lenses between 40-44mm as well as some scopes. 【Protection】These covers protect your lenses from rain, dust and scratches in any weather or environment. They also offer protection to your lenses in transit and storage. 【Easy to Remove / Add】Place the lens covers on the outside barrel of your binocular/monocular to protect your lenses. Covers remain attached to the binocular barrel and hang down when in use. 【Design】High quality flexible rubber is independently tethered and stretches for a tight fit. This ensures optimal protection for each lens. Review: Rubber lids that hang on - Works great. I’ve lost two lens protectors so far so let’s see how long this hangs on. Look just like my Vortex ones without the logo Review: Best size for Nikon Prostaff P3/P7 - Winner: 51.8-53.3mm - If you're like me, you might be wondering... Do I get the 50.5-51.8mm or the 51.8-53.3mm. Well after trying both I can say definitely get the 51.8-53.3mm. Because the Prostaff P3/P7 has a thick rubber armor the smaller of the two was too tight, you almost have to force it a little around the lens. With the 51.8-53.3 you just push it in and it fits perfectly snug, not loose or too tight. The quality of these is fairly good. I was worried they'll be too much flex on the cap but it has a nice balance between flex and stiffness. I would prefer it to be a slightly stiffer/harder but it's still good the way it is. The edges are cut perfectly smooth. One noticeable thing I like is when the cap is off, it goes straight down and out of the way of the viewing lens as shown in the photo. Definitely recommend. ## Features - 【Measuring】Please measure the Outside diameter (including armouring) of the barrels to get accurate sizing, if the tubes outer diameter is between 51.8-53.3mm, it will fit perfect.
