If your idea of hiking is more pacey hut-to-hut routes over undulating terrain than slow and steady treks at lower altitudes, then the Lightning Trousers are for you. Made from a nylon-elastane mix, they're durable, stretchy and surprisingly soft. They’re engineered with long-lasting FlashDry-XD™ technology that wicks away sweat helping to keep you dry – and, in the long term, warm. And thanks to articulation at the knees, clambering up and down over rocks or steps is blissfully restriction-free.
