What I think:
I have been wearing this jacket in varying conditions for about 2 months. I bought it for snowboarding. I am not into freestyle/park riding, so many times I buy ski shells for their superior (opinion) technical features. Of course, I was also intrigued by the allure of Polartecs Neoshell. That said this product is as advertised. You have all of the stretch and comfort of a soft shell that you would expect along with it being very breathable. The protection promised meets expectations. It really does. Completely element proof! In my opinion, Zion is on point! Additionally, if you are viewing the pics online and thinking that it looks pretty rad it does!
Some notes:
Disclaimer: I admittedly am no expert, these are just my opinions on my experiences with the product.
There is a thin layer of insulation, and I mean thin. You will need to layer if its going to be really cold out. That said, be careful bc if you throw a down vest on underneath (which I did on a really cold day) expect to be trapping some heat and sacrificing one of the best features of the jacket. In my experience insulated layering garments dont breathe exceptionally well and this shell is designed to breathe. Too bad there arent pit zips to add some airflow in those situations. Also, as I just mentioned, you can layer appropriately with this shell. You need to use thin products designed to pack down. I have been going with the Marmot Zeus vest on REALLY cold days over a capilene shirt or thin base layer as well as a Patagonia Nano Puff jacket for the not so frigid days as I find the Zeus to be warmer and fits more snug to the core. Lastly, just thin base layers work great if the temps are like 5 or so degrees above freezing. Recently, I wore a UA coldgear tactical base layer with a capilene shirt over top when temps were right around freezing all day. This combo worked great, because both have very breathable designs so I wasnt trapping any heat. Id highly recommend it. No weight, no excess heat/sweat, and STILL WARM.
How I would improve it:
I would add some pit zips just to get some additional air flow right to the core for certain situations (letting off steam on the frigid days you are rockin serious insulation OR for spring riding). I would also add a powder skirt for the consumer looking to wear this shell while riding powder. This problem can be solved fairly easily by wearing layering that has cinch at the waist, but I dont see why it cant be added. Id redesign the hood and front neck area. If you wear a helmet and want to put the hood up its virtually impossible. Just too short and you end up with the top of the zipped neck over your face in a really tight fashion.
Just my opinions - and I appreciate everyone elses on the site - Thanks!
