A good sweatshirt should be one of the most reliable pieces of gear you own. My rule for men's Bitcoin sweatshirts and hoodies is simple: they have to be seriously comfortable and well-designed. I'm a designer, so I'm picky. I try to use 100% organic cotton whenever possible, but sometimes a different fabric just works better for a specific cut or feel. Because of that, you could consider the organic pieces the rare sats of the collection—special finds you'll want to HODL onto.
