Rated 5 out of 5 by from No better jacket out there For strenuous exercises in rainy conditions, I had tried out various rain jackets before. But either it was waterproof, then I got a sweaty mess from the inside; or it was breathable, then I got soaked from the outside. After many hours of cycling in the rain during fall or winter, I can fully recommend the Theta AR. It's the best jacket that combines breathability with airtight Goretex Pro material. Awesome combination. And it's a good looking jacket to use for many less-challenging occasions. So it's a heavy price tag, I know, but it sure is worth every buck. Go for it and don't compromise on quality.

Rated 5 out of 5 by from Great jacket This Is my second theta ar jacket. I really like the benefits that this jacket has to offer. It's truly a 4 season shell, from hiking in the mountains to skiing. It's my go to rain shell during spring and summer. The jacket really breathes well, while offering rock protection. Huge pit zips Allow you to dump all that extra heat out when. Your sound hard physical activities. Great collar to protect your neck and an excellent good that offers maximum protection. I would highly recommend this jacket to anyone that likes adventuring every single day of the week. This is one of the best versatile hardshells on the market. It runs a bit big, so be sure to try both sizes that you lie between.,,6'4,,200lb,,Xl

Rated 5 out of 5 by from Expensive, But Worth It! I've had my Theta AR for about 2 months now. I ordered a large and it fits just about perfect. I'm 5'11", 200lbs, 42 chest, 32 waist. It's been great for the late spring, Pacific Northwest creeping damp. I've been reasonably dry through rain and wet snow, even while hiking with a heavy pack. Certainly no drips through the seams. The tunnel-style neck is nice too. Yep. It's expensive. But it's the best jacket I have in the closet right now. (Full disclosure: Though I purchased this jacket, I have been participating in Gore's MountainTechs product testing program since 2007.)

Rated 5 out of 5 by from Fantastic lightweight jacket for active winter use I bought it for year-round use from snowboarding to hiking. I decided on the Theta for a few main reasons. 1. Gore-Tex Pro Shell is totally waterproof, extremely breathable, without being too heavy for backpacking 2. The length of the jacket. I wanted the extra length for use in Wasatch powder(no powder skirt) and for extra coverage in violent afternoon thunderstorms. 3. I wanted a jacket that would last for around a decade, not just a few seasons. I'm 5'10" 175lbs and a large fits me just fine, has extra room but it's supposed to so the jacket doesn't ride up on you.

Rated 5 out of 5 by from Bombproof I've only owned the jacket for a couple months and so far haven't experienced any weather that has really put it to the test. I've worn it as a fall rain jacket around campus and while cycling and it's kept me warm and dry underneath. Goretex Pro makes the water bead up and roll off. Planning on using it over an Atom LT and a Cap 3 skiing this winter and can't imagine I'll be cold. I'm 6'2" and struggle finding coats that cover my entire torso, past my waist but the Theta does it. Articulation is spot on, can't wait to have adventures with this for the next ten years.

Rated 5 out of 5 by from best choice you could make I was so excited when this jacket arrived, the first thing i did was go out in the yard with the hose. It performed really well, even with the direct pressure of the hose over the fabric there was no leakage at all, the only problem was that because the AR uses a water proof zip and doesnt have a fabric flap to cover the zip water did leak through the zip. That being said when are you ever going to have high powered horizontal rain coming at you? ,,,,Perfect for anyone who spends their time in the extremes or just wants a jacket that will last for years.

Rated 5 out of 5 by from Good quality jacket seems to fit true to size Just returned another name brand GoreTex for workmanship issues (4 weeks old) to another retailer and just received this jacket today. Wanted to chime in with some dimensions to validate sizing. I'm 6'1" / 225 lbs. No gut to speak of, 35 inch waist, with 45 inch chest. This jacket fits very well, had thought of XL but it would have been too big. Able to wear long sleeve Carhardtt shirt and fleece vest underneath without any tightness issues. Hopefully this helps someone out.......I'll report back in a year or so with an update on durability.

Rated 5 out of 5 by from Exactly What I Wanted This jacket finally showed up on my doorstep today, and I almost couldn't control my excitement as I tore off the packaging and rushed to try it on over my Atom LT Hoody. It fit perfect and with the lightweight atom hoody underneath I am ready for all the weather Fargo, ND can throw at me this year. I actually use this gear to do everything from hunting and camping, to playing pond hockey in the back yard. It's athletic lightweight and tough construction makes it the perfect gear for active outdoor types who live in cold or wet areas.

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 position, 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.

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.


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.
