From the college crewneck to the ugly Christmas variety, the sweater has seen hundreds of renditions. It’s a silhouette that hasn’t seen a refreshing take in a while, leading us to think that groundbreaking innovation might not be possible—boy, Proof sure proved us wrong on that one. Introducing the 72-Hour Merino Crewneck: a remarkably soft, surprisingly durable, and stylishly versatile sweater that makes daily commutes and international escapades equally seamless. Speaking of seamless, the innovative design is made possible due to the world’s first garment printing machine. It carefully eliminates the thick, bulky seams that lead to irritation, while adding a waffle knit texture that’s luxuriously cool.
