As a climber, hiker, and year-round pant-wearer, I need something lightweight, breathable, yet warm enough for a chilly evening in camp. Recently, the LIVSN Ecotrek Trail Pants have found their way to the top of my drawer. Their stretchy nylon construction allows me to climb all day without restriction, and ample pockets make storage a breeze. Never again am I losing my pocketknife to a bottomless pouch. Available online; $130.
