I bought two different sets of Opticron lens caps: 42-44mm Opticron (Model #31050) for my Leupold Katmai 6x32mm binoculars. For reference, the original caps were stamped 43.5 on the inside and made very cheaply, as if they were just a temporary shipping cover to be thrown away after unboxing. Binoculars. For reference, the original caps were stamped 48.6 on the inside and equally cheap junk. Both Opticron replacements fit perfectly and are made from a thick but flexible rubber material that seems to last a lifetime. Only the 42-44 caps sported the 'Opticron' nickname on the outside, but the box packaging was identical on both, as was the quality construction. Highly recommended. If Opticron places so much emphasis on simple lens caps, I'm inclined to take a look at their binoculars.
