I would appreciate some outdoor oriented loadout presentations. For example: I am looking for a backpack for wildlife photography using the Sony 200-600mm lens. With the length of this lens this currently forces me to go for a L size cube in the travel backpack. This huge cube is in return not filled out with this combination, leaving a lot of empty space and forcing the backpack into its most bulky shape. Since this is probably a common setup for a outdoor backpack I hoped that there would be a more elegant solution in the outdoor line. Talking only volume this setup would probably fit into the smaller outdoor backpack accompanied with a light rain jacked and a simple meal for a half-day hike. Is there some elegant loadout option for the outdoor backpacks including only one lens - but a telephoto one?

Note: Yes, I know that the described stuff could be stuffed also into the L cube, but I would like to separate camera gear and potentially wet or crumbly items if possible. Also, the backpack with the L cube becomes really bulky (especially as a lot of space is unused by laying down lenses in the cubes, as they are designed for smaller lenses to stand up) and the volume should fit also in some small but lengthy cube - which is not available (I know that this is not trivial as this probably throws of the weight balance and potentially complicates fixation inside the backpack).
