A waterproof and breathable storm shelter packed full of features.

The Women's Theta AR Jacket leads the Arc'teryx essentials line, and it's obvious why. The Theta AR is decked out with every feature you could ever want on a wet or windy day, regardless of whether you live in Seattle, are halfway through hiking the AT, or are skiing through a heavy March blizzard. This jacket is more than an exercise in utility—articulated design provides full range of motion plus feminine styling, so your bright fuchsia manicure isn't the only give-away that you're a woman.

Guaranteed waterproof, breathable N70p Gore-Tex Pro fabric sheds snow like your dog sheds fur in July, and still allows excess body heat to escape so you don't overheat. While waterproof and breathability are key, the durability of the Gore-Tex Pro makes the Theta AR stand out in a crowd. Tightly woven strands of 70D nylon rebuke abrasions and untoward advances by rock faces, ski poles, and sharp branches, all the while remaining soft and supple.

The hood attaches at the base of the full stand-up collar, meaning you can zip to your chin and not have the hood hovering around your face. Full articulated and no-lift gusseted underarms lets you stretch for a hold without taking the entire jacket with you, an underarm vents help cool you down if you're hiking through the prelude to a mid-summer monsoon.

Most essentials have broad application and are not limited in scope, and the Theta AR jacket is no different. Layer it over a slim-fitting puffy coat for winter warmth when the snow thunder roars, wear it over a thin baselayer for backcountry touring in full sun, or put the Theta AR over your theta sweatshirt from college on your evening constitutional in town.

Cold Wet Winters

  • Familiarity:I gave it as a gift but have feedback to share
  • Fit:True to size

I got this for my mom who lives in Ohio where it often times rains in the winter at 35 degrees, very miserable. She didn't just want a winter jacket that gets wet and than is useless, she wanted something that would keep her dry that she could layer underneath. This shell is fantastic. My whole family swears by Arcteryx. This Jacket has made everything more enjoyable in the wet/cold months, from walking the dog, to hitting the slopes.


Awesome Jacket

    I really love everything about this jacket! The Mango color is outstanding and the fit perfect (runs about standard). I wore it hiking in drizzle and stayed dry as a bug in a rug. Very comfy and looks great!!!


    Length was shorter than I expected

    • Familiarity:I returned this product before using it
    • Fit:True to size

    Although, I loved the viridian color and the pockets, but the jacket hit at the top of my thighs, and barely covered my backside. I am 5'6". I am returning it, as I I already have a GoreTex golf jacket in this length, and really wanted a longer jacket.


    First Impressions

    • Gender:Female
    • Familiarity:I've used it once or twice and have initial impressions
    • Fit:True to size

    I just purchased this jacket, and have yet to try it in wet conditions. I did loads of research online, and came to the conclusion that this jacket ran large. I am about 120lbs, 36" bust, slim waist. The small fit perfectly, over a long sleeve T-shirt. But as soon as I added a fleece, it was too snug, and pulled across my shoulders. I ordered a medium, and that seems to be the right size. Tried on with a tank top, long sleeve shirt, fleece vest, and down shell (way more layers than I would actually wear) - I still had full range of movement when I crossed my arms and swung them back and forth.

    I love the length of a the jacket. I struggled between the Beta AR and the similar jacket with a snow skirt. I chose this one because it comes down to right below my rear end. Great for sitting on wet surfaces (just like the North Face coat I am replacing).

    The price tag is/was very hard to swallow. I was expecting a shell that felt a little softer - more like cloth. Jacket is well made -- but I don't like that it's made in China -- for that price tag. Looked everywhere to be able to pay below retail for this, but couldn't find a reputable online dealer (and I didn't want one in black, which is what everyone had).

    Long story short, I will probably keep it, very light weight, perfect length, seems to do what it says it will do. If you don't mind the price tag, then go for it.

    I have purchased from Backcountry in the past -- they have a great customer service, which one of the reasons why I chose to purchase from them.
