Patagonia Nano-Air Light Hybrid Insulated Jacket - Men's

A Happiest of Mediums.

As the old-timers used to say, "If it ain't broke, don't fix it." And while that adage might have worked just fine for your Granddad's steel frame pickup, the same philosophy doesn't apply to performance gear and clothing. So in the spirit of innovation and preemptively fixing things that are (or aren't) broken, Patagonia brings you the Men's Nano-Air Light Hybrid Jacket: a layering piece that manages moisture and provides adaptive warmth for those high-octane adventures.

Designed for trail running, climbing, and backcountry touring, the Nano-Air Light Hybrid continues the Nano-Air tradition with its lightweight, durable, and stretchy construction. However, this jacket's main point of differentiation lies within its airy waffle knit on the underarms, sides, and back panel, which have a CFM rating of 40 in the front and 130 in the back—in other words, this fabric expedites the release of excess body heat, wicks moisture, and dries quickly to ensure that you stay anything but over-saturated or clammy.

Much like its elder siblings, the Nano-Air Light Hybrid features 40g FullRange synthetic insulation, which is not only warm (even when wet), but also highly pliable to maintain mobility as you run, post-hole, or ski your way around the mountain. A DWR treatment protects you, the shell, and the lining from errant moisture and light precipitation, while two welted and zippered hand pockets are compatible with a pack or harness and offer respite for cold digits. Not to mention, the low-bulk cuffs feature subtle thumbholes for added coverage when you need a little extra protection.

ACTIVE winter mid-layer

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Med

I use this as my active winter mid-layer for ice climbing and for ski touring. I'm wearing a MED in the picture. On approaches, I usually have this stand alone (no shell) and the DWR finish is awesome for minor snow or moisture. I wear a 100g merino base layer underneath this jacket. I also own the Nano Air Jacket, but I use the Hybrid when I'm more active. Also, this has a skinier fit than the Nano Air. The big difference is that the Hybrid is only 40grams of insulation which is perfect. Also, the thin fleece in the back (instead of insulation throughout the jacket) is wonderful when you're wearing a pack and you won't get a sweaty back as easily as you could with other mid-layers.
Also, I'm sporting the Patagonia Dual Point pants/bibs in the picture! My go to for ice! Great for spring touring as well.
Lastly, great colors for guys! (finally)

ACTIVE winter mid-layer

Great Active Mid-Layer

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

This is a great active mid-layer, though certainly on the light side in terms of insulation. Great to wear while active with good breathability but still enough insulation where it counts.

This is certainly more of a fit cut (as described) as compared to other Patagonia jackets.

The Perfect Active Mid-Layer!!!!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Medium

First off, the Nano-Air series are the best mid layer jackets out there! This hybrid is obviously the lighter more breathable version of the standard Nano Air. I use it as a layer under my ski shell and it is PERFECT! Breathes well and maintains a good warmth. I would purchase these is you are looking for an ACTIVE mid layer. This is the best one out there. If you have the R1, Nano Air Light, and the Nano Air. You will be perfect for any weather thrown at you. I am 5'10" and 165 lbs. and the medium fits perfectly. It is a little tighter than the standard Nano Air, but thats what you want with a mid layer like this.

Let me know if you have questions!

Cold Weather Running Go To

  • Familiarity: I've used it several times

I bought this for fall/winter trail running, and have been very happy thus far. The insulation at the chest and arms keeps me warm on my way to the trailhead/in a headwind, and the stretchy knit panels dump heat really well once I've started sweating.

Breathable and comfy

  • Familiarity: I gave it as a gift but have feedback to share

Bought this for my boyfriend earlier this year and he loves it. He wears it even when he doesn't need to. Bought it for him for trail running primarily and also Backcountry skiing. Nice breathable back and very soft.

what a versatile piece!

I love my Nano Air hooded jacket but most of the time it is overkill in the warmth department and I end up using it as an insulating outer layer. The Nano Air Light Hybrid is perfect middle ground piece for moving fast with big efforts in the cold or just chilling at work when something more than a t shirt is needed.

On cold days I am able to use it backcountry skiing over a baselayer layer on the skin up and then pop an insulating jacket or shell over it on the way down. If transitioning fast it insulates well enough to even forego the insulating layer on the way down and just roll with it as the outer layer. When it's sunny and a little warmer I'll skin up in a base layer and add the Nano air light for the down. I'm always surprised at how wind resistant the chest area is in relation to how well it breathes! That is the magic of multiple materials placed in strategic places. In addition to backcountry skiing I use it nordic skiing on cold days, fat biking (heaven forbid), cold bike commutes as an mid or outerlayer, etc etc...
I love the contoured fit and at 5'9' 150 lbs feel the size small was tailor made for me. I often wear it at work in the clinic on cold mornings and never end up taking it off because it regulates temperature so well.
This is one piece that I need in multiple different colors so everyone doesent realize that I'm actually wearing the same piece everyday for about every type of activity...

Close to perfect

I typically run hot when active and cold when stopped. The original nano air was too warm for me while active. I have also owned a 40 gram primaloft gold jacket with fleece side panels (ala Atom LT) and found it didn't breath well enough on the back panel when active.

The nano air light is a great piece for me in that it's a medium boost of insulation when worn over other layers, or much warmer under a wind breaker. Since I typically am wearing a pack less insulation on the back is appreciated. I consider it to be a much more versatile fleece (can't get much out of a fleece over a windshirt).

Some examples of use:
*Ice climbing WI4-5 pitches with a thin t shirt and grid fleece around -10 to -5F. Used a thin windshirt over the top during windy approach and on easier approach pitches.

*Ski touring with no base layer at 27-30 degrees. Just to test breathability. Would sweat a bit in the front with zip down. Threw a hard shell over the top only and the whole jacket was dry and warm to the skin by the base of the run.

*Ski touring insulator for the ride down. I'll typically tour up in a very thin synthetic t or long sleeve and need more for the ski down. The nano is the perfect touch of warmth. Easier to slide on fast than any of my fleece mid layers. Dries out the base layer very fast when I do sweat on the up, especially in the back.

*Hiking and cragging in 40-50 degrees. It offers a boost of warmth on the flatter portions of approaches, if it's a steep uphill I would still strip down to a t-shirt. While cragging moderate rock with temps around 40 and some light wind I left the nano on, did not overheat climbing and was just comfy while belaying.

I see myself bringing this along for alpine climbing in the summer. On the descent of routes I think it will be a perfect boost of warmth over a windshirt. Since I can pull it on and off quickly it's much more versatile than taking a windshirt on/off to get a fleece underneath.

My only gripe about the piece may be specific to my build, but it's shared with a lot of climbers. I have relatively low body fat and "popeye" forearms, lots of veins close to the skin. My elbows and underarms have been cold when I wear just the nano light or have it over a windshirt. I wish they would have the waffle fabric cover the back, sides, and armpits only. I could use a little bit more warmth under the forearms. Minor gripe.

Fit wise, I"m 5'8" and 155lbs, most of the weight in the thunder thigh quads.


    This jacket is perfect. I love my Nano Air, but its a little sloppy in the fit. This jacket is much more slim fit and might just be my new fav mid layer... Im 6'2" 185 and the large is perfecto.

    love it

    If you like your Nano Air jacket, you're going to love the LW Nano Air Hybrid here. It takes the stretch and breathability that make the original so awesome, a step further. I've been wearing mine a ton backcountry skiing on colder days, mountain biking, and as an around town piece. I find myself wearing it even more than a regular Nano Air since it's lighter and more versatile. The back stretch panel is from a Fall trail running piece and is super comfortable with what seems like just the right amount of stretch. The thumb loops and stretch material that make up the cuff are the icing on the cake - it's not often guys get thumb loops on a jacket like this.

    I think you'd be happy matching your Houdini size and going with a medium!
