Love the jacket
I just finished running a 15k while wearing the jacket. It kept me warm (temperatures were 32F) and insulated from the 15 mph wind with only a thin base layer underneath. I am getting to the point where I have a decent collection of Arcteryx gear and I am continually impressed. I am nearly 6'2" and 215 lbs and I decided the large was the way to go. The sleeve length is always the issue for me and the sleeves on this jacket are great. I actually bought the L and XL and am going to return the XL. The XL has more room around the waist than I need and since it is for running and biking I don't want extra fabric.

Excellent Product
This jacket looks great and fits exactly. I am 6' 210lbs and the x-tra large is a perfect fit. I have already gotten to use it in the rain and it seemed to be waterproof, although it was just a light shower. This jacket is very light, but seems to be a good, tough jacket.

good jacket
I had never owned a Arc'teryx Accelero zip neck jacket before I got it, I like that zip jacket, it's the reason I want to get this full zip one. This new jacket is better than that old one in appearance. It 's so light and stylish, most of all, it stretches very well.

Good for Running
This Jacket keeps you warm. Intended to be a mid-layer, I would not recommend that you wear it in extreme wind and cold without a shell. This is made to be breathable and incredibly light-weight. Very good for running. It seems to be water resistant to light rain but it will soak through in a downpour, but it dries quickly. I am 6' and 180lbs, I bought Large and it runs a bit loose. Also the color looks much brighter than picture on the website.

I really like this Jacket.
I really like this Jacket.I wear the shirt cycling & it is super breathable, blocks wind, & repels light rain: perfect for fall weather. Absolutely a great buy!!.
