Fully equipped and built for cold-weather adventures, the "Lunar Lake" ACG puffer PrimaLoft® Thermoplume insulation to help keep you warm. The neck zips up higher than the average jacket to cover part of your face and help you stay shielded from the cold. When the weather warms up, the jacket packs down into its own cinch bag for easy transport. Combat the Cold:Nike Therma-FIT ADV technology combines heat-regulating fabric with advanced engineering and features to help keep you warm in cold-weather conditions. We used PrimaLoft® Thermoplume for its lightweight, dependable warmth. It's made with tiny fibers that create pockets of insulating air, holding warmth while letting moisture escape. It's designed to help keep you warm even when wet. Layer and Adapt:ACG apparel is designed as a nesting system so you can adapt and adjust to the climate around you. This roomy jacket was made to wear over a base layer, fleece or mid layer. Go with your normal size for layering. If you want a trimmer fit, we recommend sizing down. Packable and Plush:This puffer packs into an internal mesh stuff sack and can be used as a pillow while camping. Weather-Ready Coverage:This one's built for total coverage. A full length zipper goes all the way up to the neckline. A hood helps keep the elements out. We also added a snood to help cover your mouth when temperatures get low. Water-repellent shell fabric helps shed rain.
