The Planet Earth Ultralight Cap is part of a system of ultralight, highly technical all-weather clothing designed to take you across every climate, environment and terrain on the surface of Earth.

Weighing just 79 grams, every cap starts out with advanced material technology developed by Schoeller in Switzerland. Highly elastic, fast drying and breathable, it comes with a biodegradable fleece lining, adjustable ear flaps for the cold, and repels dirt and rain with engineered fibres that mimic the self-cleaning effect produced by plant leaves.
