How does Stone Island fit? An easy Stone Island size guide.

With great online retail energy, comes great responsibility (on our part) to make sure you've got every single piece of information you could possibly need to make your decision easy. One of the hardest components to crack? Sizing. A real cause for contention across the board, we've banded together to make sure no inch of fabric was left unturned in a proper grand escapade into Stone Island, how it fits and what size you should be looking out for.

Italian Sportswear brand Stone Island has been setting the standard since 1982, building a legacy, where science and clothing combine, with jackets, coats, jumpers, T-shirts, and sweatshirts, all finished with the iconic compass badge.

This Stone Island size guide covers our full collection, including T-shirts & Tops, Jackets & Coats, Jumpers & Knitwear, and Sweatshirts & Hoodies, making it easier than ever to get the right fit.

To find your size, start by measuring your chest. This will give you a clear idea of which size to aim for. We've gone the extra mile and measured each garment, to really give you the full spiel. And in turn, if we think it runs larger or smaller than the universal size guide, we'll let you know- with pit to pits to back us up.
