We hold our backpacks to the same high standards as everything else we review and buy, and while we'd like to pick a "best backpack," we know it's impossible to make one pick that fits everyone's style, budget, body type, and carrying needs. So we've highlighted a few of our favourite laptop-backpack models and brands: bags for the workplace, a jack-of-all-trades, a weatherproof commuter, and a single bag for work and the gym.
