The zip on a sweatshirt should do something, not just be there. Too many end up looking like an afterthought, a cheap brass pull on a flimsy placket that adds nothing and undermines everything. What we’ve been looking for is the version where the zip actually elevates the piece. A half zip that sits properly at the collar and gives you somewhere interesting to go between fully closed and fully open. A full zip in a weight that works as a layer rather than hiding under one. The construction matters too. Ribbing that holds its shape, a collar that has some structure to it, fabric that moves well and doesn’t pill in the first month. These are sweatshirts that read as considered rather than casual by default. They work with tailored trousers. They work over a shirt. They work on their own. A sweatshirt with a zip that earns its place is a genuinely useful thing to have in rotation.
