Our Nano Puff® Hoody handily manages all the chilly belays, melt-freeze ice couloirs and nighttime rope-pulling epics that even the most dedicated climbers can throw at it. It excels as a sleek micro-belay parka and doubles as an insulated jacket on quick alpine dashes. A simple, elasticized hood opening adds thermostat-like warmth, and the low-bulk, hydrophobic, highly compressible 60-g PrimaLoft® Gold Insulation Eco—with 55% postconsumer recycled content—traps heat with remarkable efficiency, even when wet. The wind-blocking, moisture-shedding 100% recycled polyester ripstop shell with a DWR (durable water repellent) finish glides effortlessly in your layering system, and a soft, wicking interior storm flap and zipper garage add chin comfort. The hoody stuffs into an internal, zippered chest pocket that has a carabiner clip-in loop. It also has two zippered handwarmer pockets, elasticized cuffs and a dual-adjust drawcord hem to seal out wind and seal in warmth.

WINDSTOPPER® Fabric provides total windproofness while maintaining maximum breathability to keep you comfortable in a wide range of weather conditions and activities.
WINDSTOPPER fabrics are soft and lightweight to provide insulating warmth without added weight. They allow perspiration to easily escape, which keeps you warm and dry from the inside, even when you're working hard. They’re also water resistant, and shed snow and water. Finally, they dry quickly.
WINDSTOPPER® high-performance fabrics are made by laminating a windproof membrane to the inside of a functional fabric to prevent windchill while protecting the warm yet highly sensitive microclimate that surrounds your skin. The WINDSTOPPER membrane has 1.4 billion micropores in every square inch to let water vapor from perspiration escape virtually unhindered, even when you're working at maximum intensity.
How does it work?
The WINDSTOPPER membrane is an ultrathin protective layer that is laminated to a lightweight fabric, making the fabric package totally windproof. WINDSTOPPER membrane is made from the versatile polymer PTFE (polytetrafluorethylene) which is expanded to create a microporous structure. These micropores are 900 times larger than water vapor molecules, allowing perspiration to pass through unhindered. This means that the WINDSTOPPER membrane adds total windproofness to any textile without perceivably restricting its initial breathability or weight.
DWR (durable water repellent) fabric finish repels light rain and snow and decreases dry times. When DWR is used in conjunction with a waterproof/breathable barrier, the DWR finish keeps the outer fabric from becoming saturated so that the breathable barrier can do its job.
