أغطية عدسات شيئية مطاطية من أوبتيكرون لقطر خارجي 30-31 مم

Slipped them right onto my 30mm objective housings and they click into place with a satisfying snap—the rubber’s thick enough to take a knock without budging. Tossed my bins in a backpack for a week of hiking and the lenses came out spotless, no grit or moisture getting past the seal.

I was worried they’d be too loose, but the rubber grips the lenses firmly without slipping, and they’ve already saved my binoculars from a couple of bumps in my bag. Definitely keeps the dust off when hiking.

These slide on snugly over the 30mm objectives and stay put even when I'm stuffing the binoculars into my pack. The rubber feels thick enough to actually absorb a knock against a rock. Exactly what I needed to stop worrying about scratching the glass.
