Size Matters
There are so many types of backpacks to choose from, each with different shapes and sizes. I’m going to get into just a few basic types, but do your research to find the pack that’s right for you. The only task that you want your backpack to handle is to fit all of your basic gear (tent, sleeping bag, & sleeping pad) inside. When choosing a backpack you should consider size, weight, and style before purchase. Two styles that you are used to seeing are school backpacks(book bags) and hiking backpacks. School packs go up to 50 liters in size, while hiking packs can go up to 100 or even higher. You can go as low as 40 liters in each style to fit the basics and still have room left over for a stove, pot, fuel, water bottle, and other essential gear. The size and weight of your load will change based on the season and may cause you to switch packs. In the winter most homeless people will switch to a 65 liter hiking pack to fit a sleeping bag that can handle the cold. At that size, you are no longer stealth to the public.
Watch Your Weight
You definitely want to consider weight when buying a backpack. Shaving off a few pounds will make all the difference at the end of the day. Your back will thank you for not putting so much pressure on it all day. Lightweight and ultra-lightweight backpacks are not as expensive as you might think. Packable daypacks are the same size as regular backpacks but only weigh half as much. The quality is pretty good too as long as you don’t bear them down with an insane amount of weight. They’ll last as long as you need them to be while you’re homeless, and if you ever need to replace them, they’re pretty affordable.
Watch Your Back
Stay away from brands like Osprey, Gregory, Northface, or any other expensive packs. People know those brands and what they are worth. Walking around with a $300 backpack just makes you a mark for tweakers. People know you probably have even more expensive gear inside your pack. At some point, someone will steal your pack. Always go with a no-name brand backpack to not draw attention to what’s inside. Keep it dusty. Stick some patches on it. Little things like that will keep the thieves at bay.
