These trousers are engineered with stretch nylon fabric featuring a double-weave construction. This offers tear and abrasion resistance to protect against rough rock when climbing or scrambling. The fabric's breathability keeps you feeling cool and comfortable on summer days. The pull-on style stretch waistband and adjustable drawcord achieve a comfortable fit that stays in place from when you put them on until the moment you take them off. These trousers come with open hand pockets for quick storage, as well as zipped side pockets to secure essentials like your phone or wallet. Finished with a PFC-free durable water repellent treatment to keep you protected in light showers, the Speed Fly Pants for men are a must-have for summer trekking and mountaineering.
