  • Stretchy straight slim leg denim jeans that perform like activity trousers

    Those clever folks at DUER have upgraded their famous 12oz Performance Denim to make it even more durable – giving you a pair of strides that look like fancy heritage jeans but perform like your comfiest pair of stretchy hiking trousers. The secret is in the mix of organic and recycled fibres: you've got cotton for that rugged denim style, Coolmax polyester for durability and breathability, and a dash of EcoMade Lycra for stretch. Add in a gusset for unmatched flexibility and an odour-neutralising treatment to eke out the time between washes, and you've got pretty much the best pair of jeans you'll ever own. This is their slim straight fit – a classic cut that's trim round hip and thigh, with a straight drop from mid-thigh to ankle.
