During the week, you're constantly racing — from your commute to a meeting to a happy hour, and then back to your bed to rack up those precious ZZZs before you start it all over again. On your day-long trek, there are a million different things you need to tote around, but you can't have an accessory hinder your pace! Which, is especially problematic this time of year when you'd prefer to keep your mittened hands in your pockets for extra warmth, rather than out in the elements juggling a strappy purse, a clutch, or even an over-the-forearm bag. That's where the backpack comes in. Ahead, we put together 24 sleek styles to let your hands stay where they belong: hidden in your puffer.
