I have the small black Cuir and can attest to the beauty of the leather -- it's silky smooth but still durable. The small Cuir also holds a lot, so if you can, try them on before you decide on size.
Yes, thanks for the advice, i am not 100% shure of the size to get... Have to try them at the store with all my stuff in it. It won't be a buy for right now though.
