A heavyweight staple from the Origin Collection. Crafted from 430gsm organic cotton with a boxy oversized fit and tonal ThreefiveThree wordmark for a clean, confident look.
Part of our AW25 Origin Collection, the Boxy Sweatshirt is a refined essential that captures the attitude and authenticity of Irish streetwear.
Cut from 100% heavyweight organic brushed cotton (430gsm), it delivers structure, softness, and substance — the kind of quality you can feel the moment you put it on.
Designed in a relaxed, oversized boxy fit, this piece redefines comfort and confidence. Finished with a tonal rubber ThreefiveThree wordmark print across the chest, it’s understated yet unapologetic — the kind of sweatshirt you reach for every day, and never want to take off.
This sweatshirt has a relaxed, oversized fit.
For a neater fit, go one size down.
