I'm excited to write a product description for a jacket that has served me well in the past. I could go on and on and on about the Patagonia Men's Nano Puff Jacket (I'll try to limit it to just "on and on"). First let me throw some details at you. The Nano Puff is filled with PrimaLoft ONE synthetic insulation which traps heat, even when wet. The outer shell is lightweight ripstop recycled polyester with Deluge DWR finish to shed moisture. All of this adds up to a slight 11.8 oz. On a thru-hike of the PCT, I wore a Nano Puff almost every evening around camp (especially in the Sierras), used it every night as a pillow and wore it in every town while I did laundry. It stood up to all I could throw at it and remains my go-to insulating layer in the winter. This year's model is even better as it has an improved fit through the torso and waist, and an added interior storm flap behind the zipper. I can't say enough about this jacket.

Durable Water Repellant
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. It's cute to think of a fabric as being afraid of water. Now if only they could make a bearphobic coating. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.
Polartec Thermal Pro
Polartec Thermal Pro is soft and plush on the inside, but has a durable exterior. It's a lot like an M&M. But not really. Thermal Pro is fast drying, highly breathable, wind and water repellent and has an impressive warmth to weight ratio. M&M has nothing on that. Too bad you can't buy Polartec Thermal Pro with peanuts or peanut butter on the inside, though.
Primaloft Gold synthetic insulation offers light weight thermal efficiency, permanent water resistance, maximum breathability and superior softness. That's probably more impressive than your resume. Maybe you should try beefing up your resume. I suggest adding "great at problem solving and not lying on resumes."

Men's Fit Guide Details & Info
Patagonia's measurements refer to body size and NOT garment dimensions. Sorry for yelling about it.
Each Patagonia product is designed and shaped specifically for its intended use, and below are their generalized four fit descriptions, and details about each fit. The Patagonia fit for each style can be found in the product description features or specifications.
FORMFITTING • Conforms to the body's contours.
SLIM FIT • Closer-fitting. Slim-fitting technical garments may be worn over baselayers and light midlayers.
REGULAR FIT • Neither slim nor oversized. Regular-fitting technical garments may be worn over heavier midlayers. Men's regular fit pants have a slimmer fit through that thigh, lower leg, and cuff.
RELAXED FIT • Drapes loosely on the body. Men's relaxed fit pants have a bit of extra room through the hip, thigh, lower, and cuff.

Greatest buy for the winter I could have ever made!!I am a total wimp when it comes to cold weather but this nano puff bails me out and makes me look like a tough son of a ******. I have yet to complain about the cold this season (Low of 27 degrees so far) whereas in years past I would have already been curled up in the fetal position next to the heater shunning the outdoors. I am dying (not literally) to test it out on a camping trip but one step at a time! I am allergic to feathers so the synthetic down does the job. I have combined this "sweater" with an Arc"Teryx Alpha Hybrid and I'm ready for sub zero conditions. Final Thought: Buy the damn jacket/sweater already!!!

Good jacket, but...I know I am going to be in the minority here, but I am not completely taken with this jacket. I love Patagonia products but am not in love with this one. First the pros - super light weight, works great as an insulation layer and looks good. Cons - the biggest con to me is that it is not very warm. I can never wear it in any temps below 45 degrees and for the price you pay for it I expected something better. I own the Patagonia Micro Puff jacket as well and would recommend the micro over the nano any day. Again, as an insulating layer, the nano is a great jacket but as a stand alone jacket, it's not worth the price.

Super warm crazy thinThis is the heaviest light jacket ever. It is called a jacket but it is crazy warm, with a fleece under it you can be outdoors for hours toasty warm. I have one and bought my husband one for travel as it smooshes to a tiny size (no bigger than his heavy boot socks). Just a personal heads up, I feel Patagonia runs on the small side. My husband is 5'11" 188 lbs we ordered the large and it is fitted not tight but fitted with a thin sweater or fleece under it. It is great quality and will last for years, I have had mine for 3 years and it in perfect shape after many washings. Patagonia is good stuff.

Dope: packability, weight to warmth ratio. Nope: fit leaves something to be desiredI really like this jacket. Makes for an awesome, easily packable extra layer. It has definitely become my 'go to' in these early spring months here in the PNW. In fact, I'd probably wear it all the time if my wife didn't have the same one in purple (we look like an awkward Patagonia commercial when we are wearing them at the same time). Didn't rate it a 'love it' because the fit isn't quite right for me. Went with a small which is on the tight side, but this is preferable to a medium I tried and drowned in. For reference, I'm 5'10", 155 with what we'll call a runner's build.,,

Great cold-weather midlayerAs usual, you can't go wrong with Patagonia. The black Nano is stylish enough that I can wear to work but holds up equally well in the mountains. Key points:,,-It's incredibly light for its insulation. I'm warm in 20F weather and people stop to ask why I'm not freezing,,-Slim fit (I'm 6', 150lb and a small is trim for me),,-Great design; the zippers work well, the shock cord around the waist is smooth, and the elastic cuffs are perfect. Plus an inside breast pocket for wallet, keys, camera, phone, etc. ,,-Only minor problem: it's not as breathable as I expected for high-energy pursuits. I was fine winter hiking in 10F, but when I try to bike in anything above 25F (there are lots of hills near me), my arms start to sweat a lot.

Love the change in fit!I've wanted to purchase this product over the years and have never been happy with the fit. I always considered this to be an alternative to the Arctery'x Atom LT, but the fit was just too boxy. Patagonia finally changed the cut and made it more fitted like the Arctery'x Atom LT or Patagonia R3. Sleeve length and jacket length are adequate (I have long arms/torso). I can wear this down to about freezing with a thin base layer and a little lower with a shell over it. Love how it packs into the chest pocket. Time will tell if it's durable, but if used mostly as a mid layer that would be a non-issue... I'm 6' 1" 220 lbs with an athletic build and I went with the XL. There is slight tightness in the shoulders, but nothing that impacts range of motion.

Lightweight, very warmI wear this jacket a lot since I purchased one a few months back. I think I like it because it is very lightweight, keeps me warm, and protects pretty well from the wind. It basically replaced my TNF Apex Bionic although I wish this jacket was slimmer fitting.,,,,This does pack down pretty small for backpacking trips which is a plus. I've used it with just a baselayer in temps around the low 30s and was fine. ,,,,I should have bought the hooded version, but obviously I wasn't thinking straight when I made the purchase.

The small, lightweight jacket that fills a big niche.I have owned Patagonia's Down Hoodie for a few years, and that jacket has probably saved my life twice. The only problem is that I live in Texas. When I leave the house in the morning it's 30F, and by lunchtime it's 80F outside. So other than when I am sitting in a deer blind at 20F or camping during the winter I find myself taking the down jacket off a lot. I needed something that could satisfy that "not-too frigid but still need a jacket that works" niche. I found it in the nano puff. It's just plain awesome, I have it in black and wear it from the house to the car to the woods and to the wards (I work in the medical field). When it does get cold, I wear the nano under my down jacket as a base layer and I can stand the wind-chill at sub-freezing in Amarillo, where the wind blows 30mph and doesn't stop. Get one!
