The X1 Jacket is made with waterproof, breathable Pertex Shield 20D fabric and has fully taped seams to keep you warm, dry, and safe from the elements. Unexpected squalls won’t hold you back. Articulated elbows, an extended tail, and lower back coverage protect you further. Despite its thick and durable construction, the jacket is still remarkably lightweight (around 9 ounces) and compact. In fact, you can roll it up into a burrito-sized bundle and stuff it into an attached pocket. The jacket also has an adjustable hood to protect your head and neck without obscuring your peripheral vision, a waist hem shock cord to tailor the jacket’s fit, and two hand pockets.
