A lightweight hybrid synthetic insulator that delivers on big routes and grueling alpine endeavors.

When you're spending a few days on a big wall or peak-hopping in the Alps, the Patagonia Nano Puff Hybrid Insulated Jacket meets your lightweight insulation needs without letting you down during sudden squalls or freezing fog. Half synthetic puffy jacket and half technical fleece insulator, this hybrid jacket insulates where necessary while still providing breathability to keep you in your climbing groove. On top, wind- and water-resistant recycled polyester shell with 60g of PrimaLoft One insulation surrounds your core and biceps so your working muscles remain insulated even if you get caught in a quick shower.
  • PrimaLoft One insulation (60g) features tiny synthetic fibers that absorb very little moisture, dry quickly, insulate when wet, and compress easily
  • Recycled polyester shell is water- and wind-resistant so you can wear it as a top layer or a mid-layer when things get nasty
  • Recycled content reduces fossil fuel consumption and the amount of waste in landfills
  • Lower body, sleeves, back, and underarms features R2 fleece, which is a midweight fleece with an excellent warmth-to-weight ratio that also expels your sweat while wearing a harness for days
  • Full-length zipper provides a little venting when you warm up in the sun and a zipper garage keeps the zipper from smacking you in the face in the wind
  • Bound cuffs and a full, brushed collar further seal out the cold weather without chafing
  • Water-resistant front zipper and pocket zippers prevent vulnerabilities in wet or snowy weather
  • Entire jacket weighs 12.7 ounces so you don't add a lot of weight to your pack
  • Two front core pockets stash climbing essentials even while wearing a harness

Fills the gap

  • Gender: Male
  • Familiarity: I've put it through the wringer

At first I didn't know what to think of this jacket, I initially sent it back, but I since got it, and have really given it a lot of use in a variety of conditions over an entire year. Honestly, it has slowly grown on me, especially after owning a straight Nano Puff pullover and hoody. I like this piece on its own, with a light base layer, mainly during high output activities. I think this is where the jacket really shines. I have used this jacket on its own, when running or biking, with a very light base layer , mainly during conditions that were in the 30's and 40's Fahrenheit. The Nano Puff coverage is in all the right places: chest and upper/top of arms and back, and the R2 fabric the same, where you need the most breathability: under and lower arms and lower torso. I don't particularly reach for this jacket when it's gusting hard, or if I'm doing a light activity in cold conditions. I think this is a pretty technical piece, and it's honestly not the most used jacket in my arsenal, but I do find that it fills in the gap between my straight Nano Puff jacket, and my fleeces. This jacket fits on the slim side, which I personally prefer. I wear a medium in this jacket, and I'm 6ft, 185 lbs, chest size 41-42 inches. *Side note: Patagonia has since updated this jacket's design in 2013/2014.

If I were to use this as a mid layer under my super apline jacket how breathable would this be? Or breathable at all.

The Nano Puff Hybrid is a great option for warmth and breathability in the alpine environment. The Super Alpine jacket has a GoreTex Pro membrane which allows it to be very breathable for a waterproof and durable mountain piece and though the Nano Puff hybrid will retain more heat when layered underneath (as it's designed to do) it will also allow you to dump heat during aerobic activities and insulate when moving slower. The combination and placement of the synthetic insulation and R2 fleece creates a great combination of breathability, durability, and warmth.

Crazy looking but I love it.

I got this on SAC. I know it seems a little weird, like a jackalope. But this rapidly became my favorite layer and the piece I always have with me. It's super soft, great neck, very light, and breathes well while still keeping me plenty warm (at least if I have a shell on). I had typically worn insulator-type sweaters under my shell, but tended to drown in sweat if I was doing any sidestepping or hiking. Now, I just open my pit zips and I'm good to go. If it's really warm, I wear this with a vest and I'm perfect.
I'm 5'7", 145 lbs with wide shoulders and, as is typical for Patty, the shoulders and waist are a smidge long in a M but I am not phased.
I don't try to rock this as a casual layer (I have the blue/green) but I guess you could if you were more confident than I!

Did you say this does have put zips?

No pit zips. I meant pitzips of my shell
