For longer trips, I use the Black Wolf Ridgerunner 80+20L Bag/Backpack. It’s three bags in one (a suitcase with wheels, a duffle bag and a backpack) and it can be transformed to suit most travel situations. I also find it really durable, and I love the “expanding gusset” which allows me to bring extra souvenirs home. The suitcase style opening and multiple compartments make it easy for me to organise and access my belongings with ease (I’m a messy and impatient person, so this is a big bonus!). For shorter trips, I always opt for a lightweight backpack – nothing more. I love the freedom of being able to carry “my home” with me without too much of a struggle. I’m not brand loyal when it comes to backpacks; whatever supports my back and keeps my stuff safe does the trick.
