Perfect size for hiking and my gear
Just bought this 20L over the weekend and really happy with how it handles. I wanted something I could handle easy on the trails but have enough capacity for a new 100-400 lens among my other gear. Mike

FirstLight Back Packs
I found the excellent FirstLight 20L Back Pack too small for what I needed to carry. The internal dimensions were slightly smaller than shown in the online specifications. Tank was happy to exchange it for a 30L in which everything fit perfectly. I am a long time customer of Think Tank and find their products and service second to none.

Love this bag!
Best camera bag I have ever owned! It feels small and easily fits into airline overhead compartments. But is is not a small bag, its just designed very well. I carry two Canon Mark 5's, a 24-70, 2.8, a 70-200, 2,8, a 50mm 1.2, a 13inch Macbook and all the extraneous stuff you need. My only complaint is that I wish there was just a bit more padding for the laptop.
Great pack... could easily be perfect
This pack is great. I have a long torso, and the adjustable harness makes the waist-belt comfortable and effective. It is just the right size for my needs. If I could change anything, I would do two things... first, make the side pockets a bit bigger and deeper to hold Nalgene bottles more easily. The second thing would be to add a side handle like the 30L has. That would make it much easier when flying.
