Opticron 橡膠物鏡蓋 MM3-4 50 Travelscope

The fit is snug and secure on my scope's objective tube, so I have no worries about it flying off during a hike. It's also noticeably thick rubber, which gives me confidence it can take a knock or a splash of mud without damaging the lens underneath. Exactly what I needed for transport.

I worried this cover would be too loose on my scope, but the rubber fits the tube's diameter perfectly and stays put even in my backpack. Water beads right off the material, giving me peace of mind during rainy hikes.

The rubber is thick and feels like it will take a knock, and it stays put once snapped on. After a rainy hike, the lens was bone dry—exactly what I needed.
