Form and function: that’s the goal when it comes to layering pieces, right? And these zip-collar sweatshirts personify that ethos. While these old school sweats faded into the background as hoodies reigned supreme, they're now back in a big way. Grab one for yourself and give the sweats you've no doubt been living in for the past year a break. You'll find that you get a lot of wear out it because it's the kind of piece that allows you to look cool but stay warm—a versatile staple that can be pulled over a tucked-in button down shirt or your favorite beat-up tee. As for whether to go basic grey or invest in a more stand-out color, well, that's up to you.
