In this video I put a bunch of different backpack sizes to the test to answer a question I get all the time: what size pack should you use? I looked at it through the lens of a pretty average one-night solo trip—nothing crazy, and not super ultra-light either. I packed the same loadout into each bag: a normal sleeping bag, normal-size tent, sleeping pad, extra clothes, puffy, gloves, headlamp, camp stool, stove and fuel, a lot of food, water and filter, toiletries, and a few extra odds and ends (including sunscreen in way too big of a container). I ran through 25L, 32L, 36L, 47L, 60L, and 70L, and the results were pretty clear. 25L was basically a joke for this kind of overnight—overstuffed, stressed, and just asking to fail. The 32L highlighted something important: liters aren’t everything, because a super compartmentalized layout can make “more space” feel unusable. At 36L I could finally fit everything, 47L felt like a very safe bet, and 60L is honestly where I like to live—easy packing, less stress, and room for comforts like camera gear. 70L is comfy and great for multi-day or carrying extra group gear, but for one night you probably don’t need it.
