The Arc'teryx Women's Thorium AR Hoody is a lightweight mid-layer which offers maximum warmth and versatility while minimizing bulk. Synthetic and down insulation are strategically mapped in areas of need. 750-fill down warms your core while Coreloft synthetic is placed in moisture-prone areas (hem, collar, sleeves, underarms). This allows the Thorium AR to be extra weather-resistant and compressible. With its DWR (Durable Water Repellent) finish, it is capable of shedding some moisture on its own, or can be layered under a shell for maximum protection and warmth.
Products on Sale are Discontinued Styles or Colors.

ARC'TERYX MEASUREMENT and FIT GUIDE
HOW to MEASURE:
Chest / Bust - Measure around your chest / bust, holding the measuring tape under your armpit.
Waist - Measure around the natural waist, which is often the narrowest part of your waist.
Hip - Measure around your hips at the widest part.
Sleeve Length - With your arms in a slightly bent postion, measure from the center of the back of your neck, along the length of your arm, to the wrist.
Inseam / Pant Length - From a standing position, measure from your crotch to your ankle.
Dress Length - Measuring the front of the garment from the neckline at shoulder to the hem edge.
Head Circumference - Measure the full circumference around the widest part of your head.
Hand Length - Measure from the tip of your middle finger to the base of the palm.
Hand Width - Measure the circumference of your hand around the knuckles, excluding the thumb.
• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.
FIT TYPE INFO and DETAILS:
Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.
Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.
Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.
Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.
Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.
• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.

So cozy and warm!My boyfriend took me to the store to "window shop" one day and kept shoving different puff jackets at me to try on. . . a few weeks later I found a package in my dryer with this one in it. He wanted me to be warm for a trip we were taking in early November and I pretty much lived in this the entire 9 days, including sleeping in it a couple of nights. I have long arms and the sleeves are the perfect length. Also, it is cut a little longer in the back than the front which is also awesome. Great for belaying, breathable, and ultra warm. Works great as a stand alone jacket and fits nicely under a rain jacket in wet weather or under my snowboarding jacket on ultra cold days. It is also ridiculously packable and I love that the stuff sack is attached to the inside of the pocket because I lose everything. I highly recommend it.

Finally a down hoody that fits!I have been looking for a lightweight, warm down jacket for backpacking/climbing for over six months. Everything I've tried has been either too expensive, not warm enough, or ill-fitting (size small was always too tight in the shoulders and too short in the arms and medium always too big overall). This jacket fits well in size medium (I'm 5'7" and 135 lbs. with broad shoulders and long arms and torso), though the arms are oddly roomy in relation to the rest of the jacket. I especially like that it's longer in back. The fill level of the down is lower and the weight heavier than something like the Mountain Hardware Ghost Whisperer, but that jacket is a lot more expensive, and I was concerned it wouldn't be warm or durable enough.

Great Jacket!I bought this jacket for my wife for Christmas. It's only been a week or so but she's been wearing everyday...even to work! She said it's nice and warm. We went for a hike and it started raining and I noticed that my down jacket was starting to get saturated while her jacket was keeping the rain out. I'm sure some of this has something to do with brand new DWR on her jacket but even the outer material that her jacket was made of seemed to make a big difference. Excellent extended neck guard for additional warmth. Highly recommend, so far....

Outstanding jacketMy wife always complains she is cold. Or at least she did before she tried this jacket. No more cold for her.
The Arc Thorium has a great cut, suits her perfectly. The weight is next to nothing. Love the design that makes it look less bulky than other down jackets.
And it does the job perfectly - keep her warm in cold weather. She uses it as a stand alone piece, or under the Fission SV jacket (another superb Arcteryx jacket).

My mum love this Christmas giftI was struggle between this and mountain hardware down jacket. their price are close, Arcteryx is a little bit expensive. At last, I bought the Arcteryx Thorium AR. My mum is 5'4'' and 128lb, size xs is a good fit. She is not outdoor fan, so this will be mostly worn in everyday. it is very warm, good enough for 40-50f with just a shirt or a thin sweater.

Not what I expected.I bought this jacket for my Wife thinking that Arcteryx has a strong name with quality products. This jacket feels and looks cheap. The zipper is under par, lack of a third zipper is disappointing and the rip stop is very thin.
Your paying for the name. Not worth it.

Super warmThis is exactly what my wife needed. She was always cold skiing and had to wear a bunch of layers to stay warm. Now she just wears a base layer, the Thorium, and her shell and stays warm. She wears it as a stand alone jacket for everyday and loves how warm it is.

This is a perfect winter jacketI absolutely love this jacket. It runs a little small, but its not too bulky and still maintains its warmth. It's great for wearing around the city or wearing out in the mountains. I've worn it snowshoeing and snowboarding under a waterproof layer and its perf.
