It holds everything I need, and that includes a Thermos flask.

The other pockets I designate for specific gear.

One holds all the gralloching stuff, one?s for gloves, face veils, clothing etc, and another stores all the gizmos such as my rangefinder, BackTrack, torch and the like.

The pocket at the front is designated ?ammo only.?

Apparently you can buy a drinking bladder that fits inside, but this would use up valuable space.

The best thing about this rucksack is its narrowness, which ensures it doesn?t get in the way or impede, when you?re carrying a rifle on your shoulder.

I genuinely wouldn?t go stalking without it.
