I can't recommend this jacket enough. The style is awesome and the colors for 2011 were really underrated. I have the Hex Flame print and it really stands out ... it's much more orange than the pictures show, they show it being more tangerine/peach colored.
I sized up once and it fits about right (I took an M, I'm 5'7", 140). They fit regular length, maybe a little longer, but it's not like you'll be rocking the ridiculous tall t look. Mine still sits about my crotch inseam, though my pants tend to sag down a little bit even with the belt to help out :/
Warmth is off the scale. I thought I'd never find a jacket as warm as my old 686 Smarty Uzi, but this thing is easily just as warm. The "1.5" sub layers are a microfleece jacket and a vest which can be worn seperately or in any combination (shell+fleece, shell+vest, shell+fleece+vest, fleece+vest, fleece, vest, shell) thanks to the fleece's and vest's ability to zip into the shell themselves and into each other. VERY versatile, although I just keep the fleece and vest zipped together. It's also nice if it's cold but clear out so you can wear just the fleece/vest combo under something else such as a hoodie if you want to change up your look.
Like I said, the whole thing is incredibly warm together. If you wore a t-shirt under it you'll be fine, though I add another layer when it's really cold (0 degrees at K-1 summit, Killington occasionally). Durability is very tough, though my Uzi is tougher it's not available anymore. You'd have to really abuse yourself to tear this thing.
Crazy amounts of utility too. There is a sealed iPod pocket on the left with a headphone line hole and a bungy cargo pocket with snap closure on the right on the inside of the jacket. The outside has a zip hand pocket on the right and left. I put my mp3 player (iPhone) on the left and my wallet and car key on the right. I use the zip pockets to stash hand warmers. There's also the lift pass pocket on the left wrist cuff and a mirror on the right wrist cuff. I don't use either, nor do I use the zip left breast pocket.
The hood is actually usuable and the powder skirt fits pretty well. I don't usually use either, even if it's dumping snow out (not that that happens out East much). Waterproof rating is 20k mm so even if it happens to rain, you should stay relatively dry.
I've worn 2 pairs of 686 pants and another jacket besides this one. They are all quality pieces and if you are a back-country type guy, these are a must have because of the huge versatility and performance. Even if you are a resort rider like myself and just need a burly jacket for those days when it's really nasty out (I don't wear mine all the time), you should grab one because they won't let you down, they're stylish and very versatile with the 2.5 system. I use the fleece/vest as a sub-layer and they work great.
Dogfunk has every size and color in S-XL 40% off. Grab it and you won't be disappointed.
