Overview: Patagonia Nano-Air Insulated Hooded Jacket
When your day consists of as much uphill climbing as downhill riding, you need specialized outerwear to keep you warm and comfortable for the long haul. The Patagonia Men’s Nano-Air Insulated Hooded Jacket delivers that performance in an attractive, functional package designed for active mountain pursuits.

Key Features and Technology
Breathable Shell Construction
The combination of a nylon ripstop shell and plain weave nylon lining offers excellent breathability, ensuring you won’t overheat during strenuous uphill climbs. This intelligent layering system allows moisture to escape while maintaining warmth, making it ideal for high-output activities.
FullRange Synthetic Insulation
The jacket features FullRange synthetic insulation (40CFM) that stretches with your body to provide generous freedom of movement. Unlike traditional insulation that can restrict mobility, this technology moves with you whether you’re scrambling over rocks or skiing through powder.
Weather Protection
The DWR (Durable Water Repellent) treatment on the outer shell helps shed light moisture and adds durability for rough terrain. Storm flaps on the front zippers and a zipper garage at the collar prevent cold metal from touching your chin and keep wind from penetrating through the zipper.
Comfort Details
Stretch material around the cuffs creates a seal to block winter chill, while zippered handwarmer pockets let you warm your hands when temperatures drop. The regular fit accommodates layering underneath without feeling bulky or restrictive.

Frequently Asked Questions About the Patagonia Nano-Air Hooded Jacket
Is the Patagonia Nano-Air Hooded Jacket waterproof?
The Nano-Air Hooded Jacket is not fully waterproof. It features a DWR (Durable Water Repellent) treatment that sheds light moisture and snow, but it’s designed primarily as a breathable insulation layer rather than a waterproof shell. For heavy rain, you’ll want to layer it under a waterproof hard shell.
How does the FullRange insulation compare to down?
FullRange synthetic insulation offers superior breathability and stretch compared to traditional down, making it better for high-output activities. While down may provide more warmth per ounce when stationary, FullRange maintains consistent performance when wet and allows better moisture management during aerobic activities like skiing or climbing.
What temperature range is the Nano-Air Hooded Jacket best suited for?
The Nano-Air Hooded Jacket works best in temperatures ranging from 20°F to 50°F, depending on your activity level and layering. During high-output activities like uphill skiing or climbing, it remains comfortable even in warmer temperatures. For colder conditions, layer it over base layers and under a shell for additional protection.
Does the Patagonia Nano-Air Hooded Jacket fit true to size?
The Nano-Air Hooded Jacket features a regular fit that typically runs true to size. The regular fit is designed to accommodate light to medium layering underneath without feeling restrictive. If you plan to wear thick base layers or mid-layers, consider sizing up for additional room.
Can I wear the Nano-Air Hooded Jacket as an outer layer?
Yes, the Nano-Air Hooded Jacket is designed to function as an outer layer in dry, cool conditions. The DWR treatment and wind-resistant fabric make it effective as a standalone piece during most mountain activities. However, in wet conditions or extreme cold, it works best as a mid-layer under a waterproof shell.
How do I care for and maintain the Nano-Air Hooded Jacket?
Machine wash the Nano-Air Hooded Jacket in cold water on a gentle cycle with a technical wash designed for synthetic insulation. Tumble dry on low heat to help restore the DWR treatment. Avoid fabric softeners and bleach. Periodic reapplication of DWR spray will help maintain water repellency over time.
