The Men's Nano-Air Ultralight Hybrid Hoody Jacket from Patagonia was made to be worn for the entirety of your aerobic, start-stop alpine missions where weight and breathability remain key. Able to make sure you're never slowed down by changing layers, the stretchy and breathable FullRange insulation dumps excess heat when you're working hard and keeps you warm when you're not. Fair Trade Certified sewn, the shell is made from entirely recycled air permeable shadow ripstop and has a PFC-Free Durable Water Repellent finish to keep rainy clouds at bay.
