This is a great bag for hikers who don't want to carry a camera backpack, or for sideline shooters.
I've had the bag for about 3 years and recently replaced on of the side pouches (originally LC-2s) with a large LC-4. While I really like this bag and use it frequently it did have an issue with hood. The LC-2 will fit a 70-200 but not the hood, so the hood had to live in the main compartment. Swapping lenses and swapping hoods was a little annoying. The LC-4 fixed that. Now the 70-200 and 17-40 are both usable with their hoods the correct way round! Saves a lot of time. The spare LC-2 moved to my Mini-trekker as it makes a great water bottle holder.
The Off-Trail 2 is a belt pack. When hiking I'll use it behind me (bum-bag/fanny-pack style), when doing the sports/journalism thing I'll have it in front. Accessability wise it beats the Slingshots, but there is definitely the issue of prefering a sling bag over a belt bag. In use the Off-Trail 2 is comfortable, sturdy and offers a good degree of protection.
For accessories there are zippered pockets inside and outside the flap on the main compartment. One is enough, anything extra I want to carry tends to get dropped into a side compartment.
The photos show the contents of my Off-Trail 2. 70-200 with hood on lives in the LC-4, 17-40 with hood on and the camera in the main compartment. 24 and 85 lenses with a divider in the LC-2. Accessories in the outside pocket of the lid.
A really nice bag with plenty of potential. It's been on many hikes with me and will continue to do so, and ensures everything is to hand when I'm at an event.
