I was comparing the nanoair, the atom, and this coat. Super happy with my choice! This jacket is light and warm and the same time. It has a great slim fit. I’ve worn it under a rain shell and on its own. I think this is my new go to jacket. I initially bought it specifically for cold weather hiking, but I find I’m grabbing it more frequently than my down coats for day to day wear.

Note on sizing: I usually have to buy a size up in north face compared to other makers. Reliably, the small fits perfect here, when I would typically wear an xs in Patagonia.

This is the warmest insulating layer I've tried so far that is breathable enough to ski tour in. I'm usually prone to overheating when I tour, but I've found it really hard to find a synthetic insulator that I can wear on the uphill for really cold days without sweating in it (and then having it freeze...bad combo). THIS IS IT! It's thick, durable, comfortable, and flattering enough to wear as an everyday piece when you're not out doing high output activities. This is my new go-to for chilly mornings on the skin track :)

I was looking at the Patagonia Air-nano for quite some time until I came across this jacket. It is truly light, yet warm. So far, I have tested it out in 34-degree weather and it held up nicely. My favorite thing about it is how flexible it is. For reference, I am 5'6 130lb, 34B and typically wear an xs/s. The small fit just right - an xs would have probably been too tight. Would recommend!

This jacket looks super cool and keeps you warm. For reference I am 120 lbs. and 5'7 and I got the eggplant in a XS. The S would have fit but I wanted it to be a little more snug. (I don't really care for layering) Great purchase.. totally recommend!

The North Face's Ventrix is one of 2017's best gear released. Most puffy jackets have 60 grams of insulation, but the Ventrix is stuffed with 80 grams of Heatseeker synthetic insulation. It has both warmth and weight comparable to your favorite down sweater. Not only does it keep you warm, but it has micro-vents in the back and under the arms, plus has additional durability on the front of your arms. It regulates temperature really well and I used it all fall spring and winter. I got both the hooded and non-hooded version. The hooded version is warmer, but the non-hooded is also great to have. I used it as both a stand-alone jacket down to the low 30's and as a mid-layer underneath my ski shell on really cold days in the 20's or below. I love and highly recommend this jacket!

I use this jacket for all climbing and backcountry skiing needs, the girlfriend started borrowing it too much so I bought her her own!

This is such a great jacket. It is warm when needed, and ventilated when needed as well. I would wear this jacket all day everyday if I could!

I bought this jacket for my wife before we went to the PNW. She loved it. It provided enough insulation to keep her warm but breathed enough so she didn't overheat. It also did a good job of keeping her dry in light rain and from the spray from the ocean while we were walking the beach.

This jacket was perfect for March hiking in Iceland, keeping me a perfect temperature regardless of the weather. I'm 5'8" and a size 8/10, and I got a large so I could layer. It's slightly fitted, but that approach worked. During hiking, we encountered temperatures ranging from the low teens to mid-40s, along with high winds (50 mph plus) and rain, yet I was always comfortable and dry. This lightweight jacket packs a big punch.

The North Face Ventrix Hooded Jacket is one of my new favorite jackets. Its the perfect layer for Skiing, hiking, and casual everyday wear. Its super easy to layer over but when its not too cool its the perfect stand alone piece. Its breathable warm and Oh so soft to the touch. It does have a slim fit, but fits true to size just keep in mind bulky underlayers are tough. The perfect mid-layer for winter and shoulder seasons.

I purchased this for my wife and this is what she had to say:
Move over, Atom LT and Nano-Air... TNF is coming atcha with some breathable insulation fuego. Historically, I haven't been a huge fan of The North Face cuts/designs, but the slim cut, sleeve-length, and smooth, minimalist construction of the Ventrix have absolutely won me over. The jacket doesn't feel quite as silky as the Atom LT or as marshmallow-y as the Nano-Air, but so far, I'd say it simultaneously breathes AND insulates better when you start working up a sweat in addition to repelling water more steadfastly. The hood is fantastic––not comically oversized, but generous enough for a hat or low-profile climbing helmet. It's quite low-bulk and packable, but perhaps a touch loftier than the Atom. I'm 5'9" and 140lbs, and size M was just the right size for my long torso and gangly arms.

Colder in Utah we need this, its warm and great for any use!

What makes this jacket my favorite for runs along the Oregon Coast? The perforated venting system.
At a recent collaboration with The North Face, I had the opportunity to test this jacket out on a trail run along the Northern California Coast. With temperatures dipping into the low 50's, the jacket's venting system pulled the sweat away from my body and released it to the surface level-keeping me cool. After the run, that same venting system, closed the vents trapping the warm air inside- keeping me warm. It's like this jacket reads minds. It knows when to open the windows, or crank up the heat. The post-run chills I've grown accustomed to never showed up. For my next active outdoor pursuits, I'm taking this jacket. Plus, the fabric feels like snuggling up inside your favorite sleeping bag.
