I keep my Galbin Binocular Case 10 around my car seat, very discrete and protected.
Whenever I need to take it out and walk with it around my body it is very comfortable, I almost forget I am carrying it around.
Quality is what I like the most of it, as all my Billingham bags, excellent and ready to take all the punishment daily work in the tropics asures.
It goes so well with my black Billingham 107 and 307L camera bags. By the way every time my wife and I travel those are at her disposal by her demand. I don´t know how but she manages to fill those with cosmetics and personal use stuff, fortunately I have my Hadley Pro to take my cameras with me.
