The Arcteryx Men's Theta AR Jacket. This longer-cut Gore-Tex Pro Shell jacket delivers clean styling and multi-sport versatility. The helmet compatible Drop Hood offers the flexability of a high collar for draft protection and a fast adjust hood.

Arc'teryx's longest cut, the Theta AR Jacket for men is designed to be the rugged, jack-of-all-trades jacket for the outdoors. Reinforced with GORE-TEX® Pro Shell fabric and stocked with features, this jacket has it all. The Arc'teryx Theta AR Jacket is an award winning shell for all-around use. Durability and performance, the Theta AR includes a Drop Hood™ and comfortable collar to keep out the draft. WaterTight™ zippers make the men's Theta AR Jacket fully sealed from the wind and rain and two hand and a sleeve pocket for all your small items. The Arc'teryx Theta AR Jacket utilizes e3D ergonomic patterning for enhanced movement and still leaves room for winter layers.

Arc'teryx decked out the Men's Theta AR Jacket for true multi-sport versatility. Ideal for mountaineering and alpine climbing, this jacket also provides your own comfortable micro-climate on backcountry ski tours. The Theta AR offers many of the same features as its brother, the Beta AR, but is cut longer (hitting at the thigh) to offer extra protection when it's really coming down. It features Gore-Tex Pro Shell three-layer construction, with the proprietary, tightly-woven N40p-X shell fabric that includes a DWR treatment to slough off rainfall while you romp up 14ers or get caught in a snowstorm at the top. The Theta AR is reinforced in hard-wear areas like the shoulders and arms with N80p-X nylon so it will handle pack straps and ice encounters season after season.

Fully taped low-bulk seams and WaterTight zippers will block out any moisture you encounter. When it starts puking, take shelter under the helmet-compatible DropHood with its draft-blocking separate collar, and stuff your hands in the two hand pockets, which are placed high so they play well with hip-belts and harnesses. Underarm zip vents let you cool off without sacrificing any protection from the weather.
While its Drop Hood and tall collar might be what initially grabs your attention, it is the total package that will have you playing for keeps when it comes to the Arc’teryx Theta AR Jacket. A fully functional Gore-Tex Pro Shell does absolute work to keep you warm and dry with a clean style and loads of technology. Crafted with maximum coverage in mind, this model rocks a longer length than you may find elsewhere in order to deliver pumped up defense against the elements. High-wear areas have been reinforced to enhance durability and an articulated shape delivers loads of athletic mobility. Dominate the backcountry year-round with the Arc’teryx Theta AR Jacket.

Arc'teryx Theta AR Jacket Reviews:


I've just recieved this jacket and have worn it for the last few days. Initial impressions are that the fit is nice and long just as the Theta fit is said to be. I'm 6'3" and have the large. It sits nicely below my bum just as I like it. I'm 180lbs and the chest fit is functional with room to layer underneath.
The hood is extreamly large. I know it's meant to fit a helmet but i've had smaller hoods handle a helmet just fine. I have to pull all the draw chords nice and tight to have it fit/sit nicely. The brim of the hood is not very sturdy but maybe it will break in and hold a nice position with time.
There are a whole wack of extra draw chords on this jacket allowing you to fine tune the fit nicely. A standard jacket would have 2 in the hood and 1 around the bottom. This jacket has 3 in the hood (extra one from the back of the neck to the back of the head) and 2 around the bottom (extra one around the hips, where a backpack waste strap would sit). The overly sized hood can be controled by the 3 draw chords so I would not call it a set back. It is very easy to put the hood up when zipped up all the way because of the 'drop hood' design.
I'll upload some photos of the jacket soon!
Any questions i'd be happy to answer

Best jacket I've ever owned!

I am 6'2" and weigh 175 pounds. I purchased an earlier iteration of this jacket in a size M and the fit was perfect. That being said, I normally wear size L tops in order to achieve the length I need.

This jacket is cut slim and athletic. It is also extremely durable. After spending 5 years around skis, packs, ice tools, whippets, etc., this jacket has only a few nicks that needed some tape. Pockets are perfect size and location for a technical jacket made for the mountains. Pricey but totally worth it at this point. While I do think you can buy a comparable jacket for about half the price, this one has the slightly better durability and features to make it worthwhile if you are either rich or going to use it often and for a long time!
