One pair of jeans to rule them all, one pair for cragging,
One pair to wear for walks and a little bit of cycling.

No need to keep Jeanius Jeans secret or safe though: they may look just like jeans and feel just like jeans, but they have hidden superpowers.

Jeanius are a slim-fit jean tailored for activity with subtly articulated knees and a diamond-shape gusseted crotch. Their fit means you can still see your feet when climbing and won’t risk catching them in mucky bike chains, but they’ll still be smart enough to wear out for dinner later. With BCI-certified sustainable cotton and four different fabric technologies, these aren’t your average pair of jeans either...

Our unique denim blend is designed to let your legs express themselves freely: striding determinedly up hillsides; contorting into awkward bouldering moves; performing ridiculous Monty Python walks... T400® polyester provides a superabundance of stretch and instant comfort, without sacrificing the natural denim feel. Plus it stops them losing their shape over time.

Cordura® fibres greatly increase the durability and makes your jeans last longer. No need to worry about scuffs, scrapes and tumbles with a truly bomber fabric that’s at least 4x tougher than regular cotton denim – gritstone come at me!

With the final two ingredients they’re comfortable in a wide range of temperatures too. Coolmax® All Season polyester wicks moisture to keep you cool and dry when you start to work up a sweat and Thermolite® hollow core fibres trap still air to keep you warm when the temperature drops.

Jeanius Jeans: denim to properly thrash about in and withstand a life lived out in the elements.

•Holy smokes, they're going quick!... Don't worry, more stock incoming soon.

Care & Environmental Advice
