Home to some of the hottest and most humid places on the planet, the equator carves through dense tropical jungles, warm seas, and crowded cities. Instead of seasons or temperature changes you’re more likely to be hit by a wall of heat, sun, rain and humidity. But as global temperatures rise and climate zones shift, designing clothing for the equator is like designing for our future.

So the Equator Shirt is built to keep you comfortable in all 40,000km of one of the most extreme environments we currently inhabit. The shirt starts with one of the lightest and softest fabrics on the planet, a rare, silk-like cotton from the Nile Delta. We then turned this into a phenomenally lightweight technical shirt by adding stretch, strength and concealed laser-cut air vents that work like built-in air-con. We’ve also added a collar to this edition of the Equator Shirt, so you can now stay cool in the heat, and get into all the places that still like you to wear collars.
