Dynafit - Cho Oyu Down Jacket - Untuvatakki

You've hit the American high peaks, and now you're aiming for 8,000-meter conquests. Given what's on your dance card for ascents, it's fitting you picked up the Dynafit Men's Cho Oyu 750 Hooded Down Jacket. For your Asian expedition, this slim-fitting lightweight down jacket packs into its own pocket for easy traveling on the flight from Minot to Shanghai and barely adds a pound to the careful weight calculation you've done. Go ahead and take the extra chocolate.
Down dominates the insulation world, with one glaring footnote. Typical down, when wet, won't keep you warm. You might as well be naked given how little benefit down imparts when the heavens open. Dynafit geniuses saw the problem and created DownTek as the answer. This treatment makes down feathers and plumules resist taking on water, regardless of the source. Sweat while skinning to the next camp or get stuck in an intense flurry of snow without worrying about the insulation falling down on the job.
Pertex Quantum face fabric lightens the load so you're not humping up 2000-foot ascents with a four-pound jacket on your back. The DWR treatment on the shell helps water bead on the surface instead of laying flat and sneaking inside. Four-way down chambers, aka baffles, ensure even and consistent down distribution, even after you've been wearing a pack for several hours. Elastic cuffs keep the sleeves snug against your wrists, and a one-hand hem adjustment makes it simple to seal out cold.
The insulated helmet-compatible hood holds in body heat trying to escape through your roof. Adjustments let you tighten the hood around your head, minimizing skin exposure when you're standing on an exposed ridge above treeline. Multiple pockets hold extra food, lipbalm, and a point-and-shoot camera to record your achievement.
