The Mammut Shoulder Tour IS Men's Jacket is great not only because of what it gives you, but also because of what it doesn't give, which is excessive weight. At just one pound, this thing lets you get after it without weighing you down. The Shoulder Tour's 750 goose down keeps things remarkably warm and feather light, so you can stuff it in your pack or throw it on your body without feeling like you're lugging an entire goose up to the summit with you. All the down is held in place by a Pertex Microlight 30D nylon shell, which is you guessed it amazingly lightweight, but also surprisingly water and wind resistant, so sudden squalls won't soak you before you've had time to throw on a shell. Mammut decked the Shoulder Tour out with two pack and harness compatible hand pockets, one of which functions as a stuff sack for easy packing, as well as chest pocket for extra storage. The insulated hood slips easily under a climbing helmet, and the unique colorways were chosen to honor the 150th anniversary of the first ascent of the Matterhorn, although those brave souls never had anything as warm as this.
