When every gram counts, when every inch makes a difference, you need the Exploration Convertible Pants. Made from a durable, stretchy mix of nylon and elastane, these trousers can withstand daily wear and tear and the challenges of the steepest, most rugged mountain trails. The fit is loose to the thigh and tapered towards the ankle, with a regular fit at the waist on the front and back. But perhaps their best feature is versatility. By mid-morning, you can turn up the hem flap for added ventilation. During the afternoon, simply remove the lower part of the leg using the practical zip. And when it's evening, you can convert them back into long trousers. They feature grosgrain zipper loops, mesh-lined pockets and a snap button fly for added versatility.
