The main reason to get any compact binocular is obviously due to their lack of size that not only make it easier to carry with you when you are actually on a safari, but it also makes it easier to pack away in you luggage to take on your safari holiday.
As far as compacts go, the 9x25 Nikon Travelite V binoculars is fairly standard in their dimensions and as such more than small enough for most people. One thing I would mention however is that if you are after a binocular that can get really small you should take a look at roof prism compact that have two hinges, like the Steiner 12x30 Wildlife Pro Binoculars that when folded are about as small as you can get.
At 255g these binoculars are also fairly light, to achieve this nikon have used a carbon fibre body that covers a strong metal chassis that in turn is covered with a durable black rubber armor that not only makes them comfortable and secure to hold onto, but also quieter. By quietier, I mean that should you hit them with something, say your wedding ring which often happens with me, the noise is muffled, which when viewing timid wildlife on safari, can be a really useful feature.
For a fairly cheap binocular these Nikon Travelite V's have fairly impressive optics that include aspherical lenses that minimise distortion and provide sharp images right up to the periphery as well as BaK-4 prisms made of superior optical glass that produces clearer images.
The Nikon 9x25 Travelite V binoculars also have multilayer-coated lenses , which means that at least some surfaces (usually the first and the last) have multiple layers of antireflection coatings.
