Opticron 橡膠物鏡蓋 適用於外徑 48-50mm

Been using these covers for a few weeks now, and they stay put on my 50mm binos even when I toss them in my backpack. The snug fit is exactly what I needed to keep dust off the glass during hikes.

Finally, a cover that actually fits my 50mm objectives snugly without slipping off. The rubber material feels durable enough to handle being stuffed in my backpack for years.

Took these on a rainy hike last week and the rubber grip kept them secure over the 48mm lenses the whole time. They slid on snugly without any fuss, and the snug fit means no rattling when I toss them in my pack.
