I’m a huge proponent of packing light. I always pack underwear, because you never know when you’ll have an accident. I use cotton underwear, because it’s comfortable and breathable. I tend to use the same clothes and accessories I wear in my day to day life, which helps me save money and space. I don’t like to use packing cubes, but I do like to use ziplock bags to organize my stuff. If I can’t fit everything in a 25-30L bag, I often take a bigger satchel, sling or messenger bag. I haven’t bought anything special for onebagging, but I have sold a lot of my belongings to make more room. I bring two books with me, a paperback and an e-reader, just in case one of them gets damaged. I also carry two laptops, a gaming laptop and a tablet, and two bags; one for my tools and one for my laptop. I’m always trying to pack light so I don’t have to carry too much around. I also avoid buying items that don’t save much room when folded, such as folding sunglasses. I like to keep things simple and only bring the essentials.
