The North Face Men's Horizon 2.0 Convertible Pant is a hiking pant for changing conditions. Pants one minute, shorts the next. That's the beauty of convertibles, convenient when you don't always know what type of weather you'll meet. The UPF 50 provides sun protection while the lightweight nylon fabric won't weigh you down. They dry fast in case of splashes from a stream, or just remove the pant leg and wade up to your knees.
