I love this jacket, don't tell my wife I said that she might get jealous. This is a great bargain compared to other brands with Polartec Neoshell especially if its on sale. I have worn this from 10 degrees to 50 degrees and have stayed warm and comfortable, you just have to layer properly. I am 5' 7" 155 pounds and a medium fits perfectly with room for a base and mid layer. I'm really impress with the performance so far it is waterproof, windproof, and breathable. My only quirk is the side pocket zippers are a little high other than this it a well made jacket.
You can't go wrond with the zion jacket, i purchased the black and blue in med. @ the marmot store in SF...When i saw mj having it on sale for $308 i had to grab another one, great all around jacket keeps me warm and dry... For the $ its worth it, great for cold weather to wet weather =)
The Zion is an incredible jacket. It breathes better than any shell I've ever owned and has proven itself completely waterproof in the 2 months I've owned it. I have used this around town, resort skiing, snowshoeing and hiking. It is my favorite jacket and the best jacket I can take on practically any outing.
Mostly love this jacket. Fabric is durable, waterproof and breathes really well. The red one looks badass. Quirks, the main zipper is very stiff and difficult to do up all the way. The sleeves are long which is great for climbing, but looks a bit goofy around town. All in all a great jacket.
