I originally got the Hadley Large (blue) but found out it was way too big for everyday use so I got the Hadley small (green). The Hadley Large is still useful for when I need to carry all my gear or for international travel. The Hadley Small is perfect for everyday use and will easily hold a Leica M plus a lens or 2. Fast forward to last December when I got a Leica SL so I needed something between the Hadley Small and Large. The Hadley Pro is perfect! Easily holds my SL with its giant lens attached as well as one M camera with lens. And the Burgundy color is beautiful! Now I have all the bases covered :-) Thank you Billingham!
