Rugged and they fit in your pocket - Leica Ultravid 10x25mm BR Roof Prism Binoculars

the quality of the optics is superlative in such a small but tough package, even in situations where light isn't as bright, so much so that I choose this small Leica over my other 10-15x50 Duovid I own.
Pros: small, superlative optics, rugged
Cons: half way around the world and i still can't find any cons
