I'm making this review to primarily touch up on a couple things I havn't read in other reviews on amazon. However, there may be a little overlap:

I just got this jacket (in the right size) yesterday. I'm 5'7, 190lbs (I should be 150-155)and I thought that a Medium may be too slim as these(Arc'teryx) can be cut tight, so I ordered the large. The large compelled me to think that the medium would fit, so I returned and received the M and it fits quite well, still giving my torso comfortable (but not sloppy) space.

Instead of going into all the pros and cons of this jacket (as there are many as other reviews have shown), let me just mention a couple things:

First off, the hood is huge. You can wear a motorcycle helmet and have absolutely no problem fitting this hood over it. I know because I tried. In contrast, when I put the hood over my head without my wearing a hat I was disappointed. The top half of the hood was just so much higher than my head it was disappointing... that's right 'was' disappointing. Later I became aware of the fact that there are draw strings on the back of the hood so u can mold it to your head 'easy'. So, the jacket was redeemed! The hood  with draw-strings accomodates the best of both worlds.

I love the crap out of this jacket. It was pouring rain in Redmond (much harder than normal) and there wasn't a drop that came into the jacket. Furthermore, the wind did not cut through. As long as you have a long sleeve shirt or a fleeze, you'll be satisfied.

Regarding areas of improvement I only see two or three:

1) I wish there was a pocket right on the top of the sleeve above the wrist; that way I could have something very accessible, and handy such as notes or a map. I know one of the 5.11 jackets does this.

2) I wish this jacket had normal pockets to put your hands do like virtually every other jacket does! Sometimes it's cold outside and I don't have gloves with me; I wish this jacket was virsatial enough to have had pockets for hands. People wouldn't 'have' to put their hands in those pockets, so I don't see how it could have hurt anything.

3) I don't think this may be able to be changed but, the jacket is kind of noisy. Since I got this for extreme weather backpacking and stealth may be a preferred mode of operation, I would appreciate it if my jacket wasn't so noisy. This may just be how a goretex jacket is but a friend mentioned my russling around and after that it kind of ate at me.

At any rate, this jacket is worth my $600 bucks. I now have a new best friend; sorry Jenny.
