Are you active in the mountains? Typically it’s hard to dress perfectly for stop and go activities like alpine climbing or backcountry skiing – until now. If you’re looking for one active midlayer that you will take you from the trailhead to the summit and back and then to the bar, the Patagonia Nano Air Hoody is what you’ve been waiting for.

The Patagonia Nano Air Hoody is ideal anytime that you’re on the move. It’s a warm, comfortable, breathable, stretchy active midlayer that will quickly become your go-to piece in the mountains. The Nano Air line up has been touted as the put it on, never take it off clothing. While it sounds too good to be true, it actually lives up to its reputation.

Patagonia makes great outerwear and the Nano Air Hoody is no exception. It’s been strategically designed to bring you the comfort of a fleece and the warmth of a puffy. Once this thing goes on, it moves and stretches with you through any activity.

The Patagonia Nano Air Hoody utilizes a 60-g FullRange™ 100% polyester stretch insulation that keeps you warm – even when wet. The insulation is sandwiched between two light and durable nylon shell materials and  a four-way mechanical stretch fabric with a DWR finish, while still allowing for 40 cfms of air permeability. What does this actually mean?

The Nano Air will keep you warm in almost any conditions, but it will still allow your body to breath while you exert yourself. It’s the ideal piece for thermo regulation. It’s kind of like magic, but it’s really just outerwear technology hard at work. Now with this magic, there is a downside – the Nano Air isn’t super windproof or waterproof. So if you’re truly out in miserable, wet, cold weather, you’re going to need a technical shell to keep out the elements. I like to pair the Nano Air with my Patagonia Triolet Jacket. It’s a fantastic combination for pretty much any situation – unless it gets below 0 F, then it’s just bloody cold.

Let’s take a closer look at some of the features of the Patagonia Nano Air:

Hood – I always opt for a hood on any jacket. It just makes sense to me. If you hate hoods, Patagonia makes a Nano Air Jacket too. The hood fits snugly and allows you to move comfortable. It doesn’t fit great with a ski helmet, but works well with a climbing helmet. It’s fully stretchy and you can take the hood on and off without unzipping.

Drawcord – The Nano Air goes to waist level. There is a dual adjust drawcord at the waist that you can cinch down to keep out the elements.

Pockets – The Patagonia Nano Air has 4 exterior pockets – 2 chest pockets and 2 hand warmer pockets. The handwarmer pockets are large and spacious. They’ll easy fit a few snacks and a hat/gloves. The two chest pockets are designed to be out of the way of backpack straps. I find them to be a bit high and a bit slim. They easily carry a cell phone or a point and shoot camera though.

Zippers – The zippers are not weatherproof, but they all come with pull cord extensions. The main zip has a wicking interior storm flap and zipper garage for next to skin comfort.

Cuffs – The cuffs utilize a stretchy material that keeps the cuff in place on the wrists or over a pair of gloves. There’s no cuff strap or velcro to deal with. The same material on the cuffs is around the hood.

Compressibility – I think the Nano Air compresses very well. It barely takes up any room in my pack – although it’s not in there very often. The Nano Air Hoody may not compress as well as a down puffy, but it does keep you warm when wet, so a bit of a trade off. It does look extra wrinkly after being stuffed in a backpack – just in case you were planing to wear it to a business meeting.

Water Resistance – The Nano Air comes with a DWR (durable water repellent) fabric finish that repels light rain and snow and decreases dry times. As long as it doesn’t get soaked, it will still breath. I’ve tested the DWR finish in humid PNW conditions and snowy Montana ski tours and it works well, but I have never got it soaking wet.

Weight – The Patagonia Nano Air only weights 385 g (13.6 oz). For a mainstay in my layering system, that’s nothing.

Durability – The four-way stretch fabric seems like it should snag and rip while bushwhacking on ski mountaineering missions, but it hasn’t yet. Most things Patagonia makes are bombproof and this garment seems to be live up to that same reputation.

Sizing – Patagonia calls the Nano Air Hoody a slim fit. I agree. I wear an XL in all Patagonia products and I wear an XL in the Nano Air Hoody. I’m 6’2″ and weight 185 lbs with long arms. The Large was too tight and crept up to my forearms. The XL fits great and gives me a bit of extra room in the body, which I like.

Are there any downsides to the Patagonia Nano Air Hoody? Well, after thinking that one through I have to say yes. No jacket is perfect, right?

  • I’ve found that the material seems to get dirty easily. It cleans up well though. Maybe that’s just the color I got?
  • I wish that the jacket was a touch more windproof, but then again if it was, it wouldn’t be as breathable, so another trade off.
  • The price for this jacket is a bit high, but it’s Patagonia. Patagonia has an outstanding reputation, an ironclad guarantee, and the jacket will last forever. I’ll probably get bored of it before it falls apart – or not.
  • The Nano Air threw a bit of a monkey wrench into my backcountry layering system. With the Nano Air I now opt for a base layer, the nano air, and a technical shell. That usually keeps me warm while on the go, depending on weather conditions.

Overall, I give the Patagonia Nano Air Hoody a double thumbs up. This item is several generations deep now and Patagonia continues to expand the color selection. The jacket seen in this review is the Underwater Blue. Buy one and you’ll use it hard. It’s the ideal active mid-layer for your mountain pursuits.
