Men's Chaos Jacket

Style# 57801OR

The evolution of our mountain-guide-favorite, the Chaos Jacket is the warmest, lightest and most packable synthetic wet-weather alpine and ice belay parka available. Perfect for shielding alpinists from howling wind and cold, damp conditions, the Pertex® Endurance® face fabric shrugs off rain and snow, and the warm, synthetic PrimaLoft® Gold insulation holds in the heat in even the wettest conditions. A carefully tailored fit allows for athletic movement, a high collar and close-fitting hood with unique side-gasket system seal out the weather and protect your face, and harness-compatible handwarmer pockets with elastic closures keep your digits warm for complicated ropework and the handling of ice tools.

My new standby (Review by Old Guide)

Originally I kept one of these stuffed into a tight packed ball in my pack in case someone got too cold far from shelter. It didn't take long for the low weight, low-key attitude of this high performance jacket to win me over to finally set aside my duct-taped down jacket. Now this is my own everyday winter jacket as well as my effective hypothermia averting, additional layer for others.

Favorite parka (Review by blakeskii)

This jacket rocks. I bought it as a parka style over layer for ski touring, and find myself wearing it around town too. 6'2", 175lb and the XL is just right (slightly baggy). I would like to draw special attention to the hood - until the Chaos, I have never had a hood that actually works. It fits, helmet or no helmet with a bungie draw chord that synches it to your head. I tour in sub zero temps with this on, covering my mouth, nose and ears, keeping me warm. It is also very durable, twigs and branches are no match for the outer shell. Stays dry in snow storms, and even light rain. Recommended.

Awesome Jacket (Review by Jonathan)

Bought the Chaos 'cause I flat hate the cold. It far exceeded my expectations. Rarely do I need to add layers on top or multiple layers beneath. Great durability and STOPS wind and water. Hood is VERY well built and performs well even without a helmet. I'm a XXL (formerly athletic build HA!) and the sleeves and back fit well (normally have issues with biceps area and not able to cross my arms).

The "sleeper" in OR's lineup, so good (Review by Peter)

I originally purchased this synth-puff as a parking lot/dog walk/bar crawl jacket to replace an old huge-puff that had too many burn holes from bonfires in it. I never expected to actually want to haul a "big synth" on ski tours, that’s what highly compressible down is for, right? I have been completely surprised that this has become one of my favorite pieces of gear, ever. It’s actually a pretty light layer of Primaloft, not too bulky, but the Pertex shell blocks all wind and sheds wet grossness, so this jacket hits well above its weight class. It’s amazingly warm, especially when it’s puking snow and windy. The hood works perfectly, easily adjustable w/ or w/out a helmet while wearing gloves. Pertex is also pretty quiet, so unlike other shell fabrics, you can still hear while wearing the hood. The side pockets have no zippers, so you can thrust cold hands in there during skin transitions without fumbling or scraping frigid knuckles. There’s a huge internal pocket for warming up liner gloves and skins on the way down. The fit is loose enough to layer over your normal gear, but won’t flap in the breeze. The hem sits low, protecting your butt when skiing deep pow. In other words, this is a furnace level synth-puff worth packing in your ski touring bag.

Top Shelf (Review by Coldy Locks)

The Chaos is top shelf. I've never owned a nicer jacket. Super warm, lightweight, awesome functionality. The hood is great; super warm, nice draw strings. Jacket fits great; I'm 6' 215 lbs. athletic build, bought an XL, couldn't be happier. If you're on the fence about another jacket, let this review sway you, you won't be disappointed.

Men's Chaos Jacket (Review by cascade climber)

I think the OR Chaos is the best synthetic parka on the market. I prefer it over midweight down jackets because it's just as warm and far more durable. The Pertex Endurance fabric is light but not flimsy like a lot of down pieces. Won't have to worry about your expensive jacket getting ripped every time you use it.

The new model is a little more "athletic" fit than previous years I've worn (2009 and 2012).
