600-fill down keeps your fingers and thumbs warm as the mercury hits new lows.

Great stuff for extreme cold The North Face Nuptse Mitt is packed with warm 600-fill down insulation for some of the best warmth-to-weight ratios you'll find for mountaineering mitts. While the design is articulated there's only so much dexterity mitts can offer so if you're looking at mitts instead of gloves we're assuming that your priority is finger warmth--which the Nuptse delivers on all counts. The exterior waterproof and breathable HyVent™ shell has water-resistant goatskin leather along the palm and key abrasion areas to help keep you covered even after several seasons of gripping unyielding shards of ice and rock.
