Think of this combo as the Chuck Norris of tech outerwear—tough as nails. The FlyLow Stringfellow ski jacket’s two-layer twill construction is extra durable to combat sharp rocks and tree branches, while a DWR treatment and 10K/10K rating stave off the elements. The Chemical pant has a 20K/20K rating and three waterproof pockets. It utilizes YKK zips and is also fully seam taped to keep you from getting soaked. Inner and outer thigh vents help regulate temperature, and Cordura reinforcements in the knees and cuffs stand up to any enemy you may encounter.
