Hiking is made easy with the Exploration Trousers.

Firstly, there's the lightweight stretch fabric that doesn't stick to your skin and moves with you, instead of restricting you. They're relaxed through the thigh, with a regular front and back rise and a regular-fitting waist for all-day comfort. Then there's the roll-up and secure hem feature for providing a little bit of lower leg ventilation.

And finally, the water-repellent finish comes in handy for shedding light showers. They feature two zipped hand pockets and two larger zipped pockets on the thighs.

The waistband rides comfortably under a harness or hipbelt, and secure pockets include an easily accessible one at the thigh.

Hike far, discover what’s out there, and be ready for what the trail brings. Rugged terrain, hot sun, washed out bridges, a quick jump in the lake – this what the superlight Gamma Quick Dry Short is made for.

High-performance TerraTex™ stretch nylon is wind resistant, durable, and dries fast. The trim fit’s articulated patterning frees you to move, the adjustable waist belt rides comfortably under a pack, and five zippered pockets – including one at each thigh – are accessible and secure.
