This snap neck pullover from The North Face is an incredibly versatile second layer. The snap collar allows for a cozier fit around the neckline in order to prevent loss of heat. Essentially, it functions as a built-in scarf while being less cumbersome than a regular scarf or neck gaiter. This design also fits nicely under a coat, allowing you to use it as a primary layer indoors and a base layer when you hit the slopes!
