I started out giving this a 3 star review, but then I changed it to 4 stars, and finally I changed it to 5 starts, because if you get the right size then everything is perfect, so I won't take stars off for that, but beware, because contrary to popular belief, size does matter and even though I live in Texas, bigger isn't always better.

My observation about its size not being what I expect and typically get from other brands in a medium was shared by another reviewer who stated stated that they usually buy large jackets and the medium they got of the same jacket was a bit loose.  Apart from it being a bit 'generous' around the torso for a medium, the sleeves are a bit long, and if I was getting another one I would definitely be ordering a small.

Prior to its arrival, I was really excited to get the jacket because of the fact that it folds up so small for travel. Taking the jacket from the bag, I was  immediately aware of the quality of the jacket from the perspective of its design, the materials used, and the construction methods. The material itself has a great feel and the zippers look, sound and act as you would expect on a quality (and somewhat expensive) jacket.

In Texas, we don't get many super cold days like one would expect in Boston or NY etc, but there are many days where this jacket would work perfectly in winter because it will keep you nice and warm, but not too warm. I would call this a Los Angeles winter Jacket :)

PROS
Great fabric - strong and has a nice feel to it
Great quality zippers
Super light - for travel
Folds up tiny into one of its own side pockets - for travel
Has a second windflap (listed as a "Widnflap" in the product listing comparison table) zipper inside the main center zipper at the front
Made from recycled Pet bottles - no, not that kind of pet - I thought so too and had to Google it (polyethylene terephthalate )
Lined with PrimaLoft Sport (60 gm2)
Elastic in the cuffs to keep out any cold
Dropped rear hem
2 zippered side pockets
1 zippered chest pocket for your phone
2 zippers (one behind the front zipper) to close the jacket and keep even more cold out.
Stand up collar
Chin guard

CONS
The size is a big (no pun intended - okay, well kind of intended...) issue for me, but that is fixable by returning the jacket, but that's not a great experience for the customer and it is a unnecessary cost for the manufacturer if enough people feel the same about the size and it generates a lot of returns. For me, where that would be the worst experience, would be if I found out I had to travel somewhere within a day or two, and I ordered one on prime and it got here and I find that it is not the right size then any brand would run the risk of loosing me as a customer because I would lose confidence in getting what I would expect in relation to size. For products where features like the price/quality ratio is unbelievably weighted in the favor of the customer, or the style is so unique and you cannot get anything like it from another manufacturer, then we overcome situations like this, return the product and get a different size and move on. For this jacket, I'm not sure that it will completely hits those markers for every customer.

Not this is not really a con, it is worth mentioning as more of a feature request.
While it was not listed in the features of the product, when I tried out the chest pocket, I immediately looked to see if there was a pass through hole for a headphone cable, but sadly there isn't one, but it would be a nice addition.

SUMMARY
Great quality jacket, but take into account this is cut larger than what I expected for a medium, and another reviewer had the same experience. When you get the size that works best for you, then I have no trouble stating that you will love the jacket.
