An ultralight weatherproof shell

The Planet Earth Ultralight Shell is a highly waterproof and breathable protective shell which combines extreme weather resistance with low weight. It’s 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. Each jacket starts out with advanced material technology developed by Schoeller in Switzerland, before being assembled at a cutting-edge Portuguese factory that builds skin suits for elite Olympic athletes.

Engineered with a diamond weave

The outer layer is engineered with a structured, diamond-patterned weave which creates strength and stability without adding weight. It’s also been treated with a water repellent coating so that rain beads off its surface. The middle layer is an intelligent waterproof and breathable membrane. And the final layer next to your skin is a soft and abrasion resistant Nylon mesh backer, specifically designed to be seam-sealed for waterproofness.

How the membrane works in the cold

This c_change® membrane mimics natural structures like flowers and pinecones, opening and closing in response to changes in temperature, humidity and sweat. It’s designed to keep you at a consistent temperature by combining really high breathability with heat retention. While it can open up like a series of microscopic vents to let heat escape, in the cold it closes itself like a protective barrier to stop heat leaving. So as soon as the temperature drops, or you stop moving, the membrane contracts to insulate you and retain heat close to the body.

How the membrane works in the heat and wet

As the air temperature rises, the membrane opens up so that excess sweat and heat can escape through the jacket. But while the membrane’s polymer structure opens up to become extremely permeable to water vapour leaving the body, it remains completely waterproof on the outside. It means that even if you held a jacket under a downpour in extreme heat, the jacket will only ever let the water through one way, while still letting heat pass through it.

Ultra lightweight at 350 grams

At 350 grams this is a phenomenally lightweight and packable weatherproof shell. When you’re wearing it you hardly notice it’s there. Or it folds down small enough to make it into almost any bag. Pair it with our Planet Earth Ultralight Pants and your whole system will only weigh 625 grams. And while lots of ultralight clothing is completely stripped back to save on weight, we’ve not sacrificed features like zipped pockets that make the jacket as practical as it is lightweight.
