When every gram counts. When every item has to fight for backpack space; you need the Exploration Convertible Trousers. Made from a stretchy but durable nylon-elastane mix, these trousers stand up to day after day of wear and the challenges of steep switchback trails. When it comes to the fit, they're relaxed on the thigh before tapering down to the ankle, with a regular fit at the waist and back rise. But perhaps their best feature is their versatility. Roll up the hem for mid-morning ventilation. By afternoon, you'll be zipping them off mid-thigh. When evening comes, convert them into trousers again. And finally, the water-repellent finish makes quick work of light showers. We've updated this season's iteration with new belt loops and a secure zip fly with a snap button closure, bringing even more versatility to this warm-weather must-have.
