Arc'teryxTheta AR Jacket - Men's

Your own impervious micro-climate.

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.

Versatile Jacket

  • Familiarity: I've used it several times
  • Fit: True to size

Always a fan of Arcteryx minimalist design great for anything between city use, breaking trail, or a shell for skiing. I find that this jacket is extremely breathable the material is durable, and the look is fashionable. Trust this jacket to keep the water out and the air moving.

what pants are those?

I have the sidewinder SV for over 3 years now and it still looks pretty new because the whole jacket is made with n80p-x. The theta is a mix of that and n40p-x. How rugged is this jacket abrasion wise?

The n40p-x is still a very durable face fabric. The Theta AR is designed as a solid hardshell, good for year-round use. It's great for hiking/trekking in the spring/summer/fall and also works well as a ski/snowboard jacket (altho it doesn't have a powder skirt.) Having said that, it really depends on what your objective is. If you're going to be using this in an extremely abrasive alpine environment you might consider the Alpha SV, which uses n80p-x only.

I had the alpha sv for a few years also. I know that it was very durable but never got use to the pockets cause im not a climber. So I sold it and got the sidewinder. I always like the look of the theta. I generally just use my Arcteryx gear for snowboarding and the NYC weather. Thanks for your input.

what are the differences between the Theta...

what are the differences between the Theta AR and Theta SVX? besides $180 in price.

Best Answer

The differences between the two jackets, when compared from the listed specs on Arc'teryx's website

are as follows:

-The Theta SVX is listed as being "highly durable," whereas the TAR is listed as being "durable."

-The TAR is listed as having "gender specific patterning," whereas the TSVX does not boast that feature.

-While both jackets have a laminated brim on the hood, the TSVX is listed as having the "StormBrim,"

which is purportedly "longer in length for extra protection from the elements."

-On the construction, I'm a bit confused, due to the fact that they are both made of GTX Pro 3L material,

but the TSVX is the only jacket that has specified features stating that it is comprised of "GORE-TEX

three-layer construction." I find that interesting, because the TSVX is shown to be made solely of

N80p-X GORE-TEX Pro 3L, whereas the the TAR is shown to be made of both N80p-X GORE-TEX Pro 3L &

N40p-X GORE-TEX Pro 3L materials, so I'm unclear as to what the discrepany in listing specs is on the

Arc'teryx website.

-While both jackets have chest pockets with laminated zippers, the TSVX has both an EXTERNAL chest pocket AND

an INTERNAL chest pocket in addition to an internal mesh pocket; on the other hand, the TAR has an

INTERNAL chest pocket, and that seems to be about it.

Cont. from above, sorry about the length....

-The TAR is shown to have "full seat coverage," so you can pop a squat when the ground is nice and soggy,

keeping you totally dry while you grub a delicious trail bar; moreover, it is shown to have "reinforced

shoulders, arms and hips," whereas the TSVX is listed as having neither of those details.

-The TAR is catalogued as having a "Helmet compatible DropHood," where on the other hand, the TSVX has

advertised as having a "Helmet compatible StormHood." I do not actually know what the difference is between

those two hoods, if there is any extant difference at all... perhaps that harks back to the foregone "StormBrim,"

just a thought.

-The TAR is presented as boasting "one-hand adjustable drawcords," but it doesn't seem as though the TSVX

mentions that feature.

-Although this seems to be a somewhat trivial addition to the spec lineup, the TSVX is shown to have a

"laminated high-strength hanger loop," though I guess that would be a potentially large pro if you are used

to having jacket loops snap while they're hanging up.

-Finally, both the TSVX and the TAR vaunt WaterTight Vislon front zippers, it is apparent from the listed

specs that only the TSVX has a "double back flap to ensure weather protection." Now, if that is the

equivalent of the TAR's "full seat coverage," I cannot say; it is definitely something worth thinking about or inquiring
