In this video I break down what I personally look for in a high-quality travel backpack—because if you’re trying to travel light, do the one-bag thing, and still maximize carrying capacity, the features matter. I start with materials and durability: I always look for sturdy fabrics like polyester or nylon, and I want the bag to be waterproof or at least water resistant since you never know when your backpack is going to get wet. From there I get into comfort, because if you’re wearing a pack for hours at a time, padded shoulder straps and solid back support aren’t optional. I also like having a sternum strap to reduce shoulder strain, and a hip/waist belt to shift some of the weight down to your hips. Next I talk storage and organization—multiple compartments, side pockets for a water bottle or umbrella, and small-item organization for things like cards, wallet, passport, phone, and even a key clip for keys. I’m a big fan of suitcase-style clamshell storage with a mesh zip side, plus an open side that works perfectly with packing cubes. I also cover carry-on sizing (think 22 x 14 x 9 inches on average) and volume recommendations: 30–40L for a 2–3 day weekend, 40–50L for about a week, and 50L+ for longer trips like hiking or camping. I wrap up with bonus features like quality lockable zippers, multiple carry handles, and a hidden security pocket—then I point you to the Tortuga 40L travel backpack I used in the video.
