The Arcteryx Men's Theta AR Jacket is a favorite among Moosejaw employees and seasoned veterans alike. I'm not trying to say we're not seasoned veterans, some of us are. I'm just saying that Steven in accounting loves his Theta AR for rain protection from his car to the office, whereas J.T. utilizes his for backcountry skiing. Fully featured with GORE-TEX® Pro Shell, pit zips, anatomical shaping, pack pockets, taped seams and tons of other features, this all-around technical mountain shell will handle whatever you throw at it.

Moosejaw Staff Pick
"The Arcteryx Men's Theta AR Jacket is totally awesome, you guys. The Theta AR makes a great rain jacket in the spring, and an even better hardshell in the winter when you learn how to layer properly. Plus, you get to look like a total pro when everyone else around you is wearing boring jackets."
Matt - Moosejaw Secret Headquarters

Rated 5 out of 5 by from I am in love with this Jacket!! Well where do I begin. First off the fit is quite large. I am 6'2" 200lbs and I am wearing the medium in this. I can easily layer under it as well. I have used this jacket for 20 degree (Canadian Celsius ehh) rainstorms backpacking, -40 layered up snowshoeing, and everything in between. Breathes perfectly and always stays dry. Longer length is great it does not ride up your back with a pack on like some others do. Comes about half way down my as*. HUGE pit zips when needed. Articulated hood is great and can adjust to fit head and helmet no problem. I will buy this jacket over and over again! Arcteryx is amazing to deal with and the fit is perfect.

Rated 5 out of 5 by from Versatile and Bombproof Hardshell The main reason I bought this jacket is because of it's versatility. I have used it for hiking, backpacking, ice climbing, mountaineering, and snowboarding and I have nothing but good things to say about it. The extra length on the Theta is great as it covers your butt and the jacket is reinforced with the heavier Gore-tex in key wear areas like the butt, shoulders, hips, and elbows. ,,,,I think the Theta is the #1 best all-around jacket for multi-sport activities and even everyday wear as a rain-shell. ,,,,As for fit, I am 6'4" 215lbs, athletically built, and I bought a large. The jacket does run a little big, but the large is perfect for throwing over my base and mid layers.

Rated 5 out of 5 by from Best 4 season jacket Hola,,,,,I've had this jacket for about a year so far and I absolutely love the performance and look of the theta AR. I use this hard shell for every season in the Colorado Rockies, from summer trekking to powder days at Vail. This jacket is the most versatile weapon in my arsenal, there nothing this jacket can't do. I feel that the breath ability has improved drastically over the years, it doesn't breath as good as a Neoshell, but it's pretty dam close. The only time I don't use the jacket is when its over 65 degrees. The jacket is tailored more towards a taller athletic build and the sizing runs about normal. If your looking for a versatile jacket that will also look good around town, then the Arcteryx Theta Ar is your main choice.,,sizing,,6'4,,200lb,,Theta AR XL

Rated 3 out of 5 by from Great jacket, let down only by noisy fabric The Theta is noisy. It rustles with every move – think cheap plastic raincoat! I guess this isn’t a problem in the wilderness; in fact, it’ll probably keep bears at bay, if bears are a problem in your neck of the woods, although where I live there are only Koala Bears, which aren’t known for their savagery. But forget about sneaking up on wildlife in this jacket – save that for the NeoShell, or Event even. I don’t know why Arcteryx chose this outer fabric – maybe it’s bullet proof, but I have everything from U.S. army Gore-Tex, to the latest Polartec NeoShell and nothing rustles like this. And it is the outer fabric we are talking about – the Gore-Tex is only a membrane sandwiched between fabrics. Now, with the noisy fabric issue out of the way, what do I like about this jacket? Everything else! The quality is top notch. The design is spot on and I love the long cut. It looks stylish and has loads of pockets. If it wasn’t for the noisy fabric I would award it 10/10.

Rated 5 out of 5 by from Stay dry! Wore this in NZ hiking all day in constant downpour. I was the only one at the shelter whose rain gear did not fail. Lots of envious looks.

Rated 5 out of 5 by from Best shell ever! I was issued the Arcteryx Leaf version of this cold weather system. It's the best water repelling shell on the market, and it's form fitting. It's got cooling vents under the arms. If you're summer hiking you can wear it all by itself and stay cool if you're really putting out.

Rated 5 out of 5 by from Everything they say is true Bit the bullet and took advantage of a good sale at Moosejaw. This is the highest quality shell I've ever worn. Durable, light, wind/water proof and nothing unnecessary in it. I recently wore it on a snowshoe trip and also skiing. Layered up great with my Thorium down jacket. Sizing chart says I should be a medium but I listened to the reviewers and got one size down and it fits perfectly.

Rated 5 out of 5 by from Awesome! This was the first Arcteryx product I finally decided to get after reading reviews on jackets for a year or so. It is an amazing jacket. It is very versatile. I have used it backpacking and I also use it as a winter shell. Whenever it rains, I have to run outside now with this jacket on. I have used it for about a year now and it shows no signs of wear.

Re: prior question, what I meant to ask was how would the chest fit on the Theta AR compare to the Beta AR? If I find the Beta AR too snug in a med, would I experience the same fit in the chest with a Theta AR?

Asked by: Matchewy
Thanks for the questions! Both jackets will have a "Regular Fit" - so I would say the chest fit will be the same. The only differences between the two models is the length. The Theta series offers the longest length. I did measure both Theta AR chest sizes. Medium is 48 inches and Large is 51 inches. Hope this helps!

I moved freshly cut cedar logs while wearing this jacket and it is now stained with cedar sap.  Anyone know how to remove these stains?

Asked by: Moser317
Hey there, Thanks for reaching out to us! Have you tried hand sanitizer or rubbing alcohol? Apply a small amount of either one, moisten a soft cloth and blot the sap. If the sap is thick or the area is large, pour the cleaner directly onto the sappy area and work it in with your fingers. Launder the clothing as usual with regular laundry detergent and warm water. Prior to placing the piece in the dryer, check to ensure all of the sap was removed. If any sap remains, repeat the above procedures. I hope this helps you out of your sticky situation!

I just bought this jacket and love it, but, it's loud. Like, annoyingly loud. Does it quiet down over time or after washing?

Asked by: Skeen
Hey there, Thanks for the awesome question. Unfortunately this item will not get much quieter over time. The material that this jacket is made with is the reason that it is so crinkly and noisy. Most waterproof shells are a bit on the noisier side of things! I hope this helps.
