The most amazing piece of outerwear on the market today!  Windproof and water-resistant, the Nano Puff® Pullover is warm, incredibly lightweight, highly compressible and can be worn as insulation or outerwear in cold climates.

Comes in Men's and Ladies' styles, minimalist, sleek and surprisingly warm, the heat-trapping Nano Puff® Pullover has these Special Features:

• Blocks wind, sheds snow and uses the best available synthetic insulation, Patagonia's trademarked PrimaLoft® One
• A deep-venting quarter-zip minimizes weight & bulk and maximizes warmth
• The 100% recycled polyester ripstop shell glides and slides  effortlessly, whether worn as an outer or midlayer
• It's weather-resistant and windproof enough to wear as an insulated shell in a gusty snowstorm
• Trim enough to pull on for high activity level
• Warm enough for quick cold weather exposure and dashes
• Made of Low-bulk, hydrophobic, highly compressible PrimaLoft® One (60-g), insulation that traps heat with remarkable efficiency, even when wet
• Pockets: One external zippered chest pocket doubles as a stuff sack into which you can pack the Nano down to practically nothing (has a carabiner clip-in loop when stuffed - carabiner not included)
• Most amazing is this - leave it on when you go inside.  It's unique properties and fabrication allows your body temperature to self-regulate (hard to explain, but it does and it works)
• Elasticized cuffs and hem seal out wind and trap warmth
• Weighs:  8.6 oz
