What are the options for strapping things to the outside of the pack? My tent, while small, is a little long and narrow and I would prefer to be able to attach it to the outside of the backpack so I can have more room on the inside.
There are 4 viable options. A tent can be easily attached to the side using the compression straps. However, you will lose the use of that side pocket. Outside or underneath the sleeping bag compartment using the vertical compressions straps will work. You can also attach it under the top lid.
You can also slide the tent poles underneath the side pockets, and then put your tent in a compression stuff sack inside the pack.
