Very Nice Shell

I bought this shell about three months ago and up to this point I've been very happy with the purchase. I am a big fan of Outdoor Research, which produces a top of the line product backed by an outstanding "Infinite Guarantee." In addition to the outstanding return policy available on, I had no reservations in making the purchase. I was looking for a technical shell that was absolutely waterproof as well as breathable. I've used this jacket hiking around Northern New York in and around the ADK Park. Because it is only a shell there is little to no insulation to speak of (although it does keep the wind out) as a result I paired the jacket with a Patagonia Down Sweater and it keeps me toasty warm with only a t-shirt underneath, down to zero degrees (below that, a nice base layer increases the performance). The shell is extremely waterproof and the DWR coating really beads the water. I bought some Grangers DWR to reapply in the future. In terms of breathability, I have been happy thus far in the cold winter conditions, although I am interested to see how it performs as the weather warms. I was unsure how I would feel about the TorsoFlo vents as opposed to traditional pit zips but have been happy with them so far and do not view them as any better or worse than the pit zips. Two minor negatives that I have to address... First, all the pockets are made of mesh and there have been some snags on items I've put in my pockets, I'm afraid a tear in the mesh will render that pocket useless. Second, The jacket does fit snugly around the chest and underarms, but no to the point where it is unbearable. I am six feet tall weighing about 230 -235 and the XL fits nicely.

Great 4 season jacket for the wilderness

I'm a big of fan outdoor research as well as backcountry, the ability to return or exchange or service a product under warranty has a lot to do with my decision to buy a particular product. So far I've gone through 3 OR gore tex shells in the search for the right now, I would say for my purposes the Maximus fits the bill.
I use my shells all year, from summer rainstorms and Noreasters , week + expeditions with rain every day, to winter camping and mountain trekking to snowsports, and in combination with the right layers for each season or conditions, the versatility of the Maximus is one major appeal. The Pro Shell definitely breathes best of the Gore materials in my opinion, though you can still heat up fairly quickly in warm weather or if overlayered. The pro shell is also by far the most durable.
The first OR shell I started with was the OR Foray made of Paclite, which blocks wind and insulates very well, however it does not breathe as efficiently, and will eventually have its membranes clogged by water leading to clamminess and interior moisture buildup. Compared to the Paclite material, the Pro Shell in addition to breathing better will remain waterproof in spite of length of exposure if seams are properly sealed (I have sat in snow for hours in pants made of Gore Pro shell and was neither cold nor wet.) I returned the Foray only because the outer fabric on the shoulders began to wear away from rubbing against a backpack.
Before replacing with the Maximus, I exchanged the Foray for the OR Mentor (on sale, paid the difference) which is also Pro Shell, however has some slightly different design elements. The material is slightly thinner under arms and on the body, and thicker on high wear areas such as the back. The mentor jacket was ridiculously tight under the armpits, a major difference in fit from the size small of the Foray which could fit multiple layers comfortably. The mentor was tight with nothing underneath. I have an athletic build with wide shoulders and chest, but am only 5' 5" so anything bigger than small would have been too big.
Compared to the Mentor, the maximus has significantly more armpit space, mainly due to the pit zips actually starting at chest level, and not in the armpit itself. creating cluttered and improperly fitted rigid material.
I can understand other reviewers complaints of the tight pits, and I would say that compared to other jackets there definitely is a slimmer cut. OR has an interesting range of differing fits across their products, so if one particlar jacket does not fit, another may as did in my case. The Foray was by far the most generous fitting of the 3 OR Gore tex shells I tried.
Like I said, for my purposes, the Maximus has met my needs perfectly thus far, and I expect it to continue to (and if not its under warranty), so I give it 5 stars. Also do like I did if you can, experiment with the different jackets, exchange them as many times as you need to find the right one. It would be great if OR was made in the USA, but since they arent, they can afford the excellent infinite guarantee which allowed me to narrow my choice to the right jacket. While I personally did not pay full price for the jacket, I think it would be worth it compared to full price on other brands of similar shells. Get it on sale if you can, or get one of the other OR products and exchange it later and pay the difference to upgrade. Thats my .52 cents. Enjoy the outdoors!

I dig it

I'm pretty skinny, so the armpit thing wasn't an issue. I've stayed warm and dry inside and out. At first I thought that the venting system- poncho style rather than pitzips- was a bit wierd, but I use it more often than I've ever used pitzips, never forget to zip back up, and it vents really well while fitting over a belt buckle.

Big disappointment for the money

Well this just arrived and I gotta say it was a let down. I got the right size but the fit around the armpits is beyond annoying, so tight you can't layer with that problem. The first 5 mins of owning it one of the hood draw cords snapped. So ya do yourself a favor and avoid this jacket. Shame could have been so good. Let's make it in Seattle that would help. Just say no to made in Asia. 6 foot, 205, large fit great other than the armpit blunder. WTB pit zips.

6'2" 205 I got XL And I love it. Perfect for layers, but most of all I can reach above my head with no raise in the jacket. This is why the shoulders feel funny. I bet Joey got mad and broke the drawstring cause mine has held up through alot.

Tight pits

I agree with the other review that this would be a perfect 5-star jacket if it weren't for the tight fit under the armpits. I'm 6'1" & 170 lbs with an athletic build and went with a large for the arm length. Even with it being pretty baggy everywhere (the arms themselves are quite baggy) else, the armpits are pretty tight. I think this may be due to the redesigned "torsoflo" venting. OR usually has full pit vents. This jacket however has a hem (bottom of jacket) to below the armpit vent. The design changed on this jacket to where the zipper doesn't actually go up to the armpit (or through to bicep as usual). Appears they didn't measure the cut properly for this new design, causing it to be too tight. This wasn't a deal breaker for me and once wearing it on the mountain for a while, I completely forgot about it. It's definitely more noticeable when you first put the jacket on. Again, other than this, it's an incredible jacket well worth more than the asking price.

Pits are tight for climbing!

Style issue. Sleek is in. You don't want to be caught in that 90s era big boxy cut shell anymore. Let's not pretend that functionality rules the day.

Nearly perfect

So close to being my perfect shell jacket. Simple, practical design and generally a great fit; perfect length in the body and the arms. My main gripe is the fit under the arms - it is described as an athletic fit jacket but you might need an un-athlectis build, it is very tight under the arms, annoyingly so. Won't have much room for more than a merino base layer under this one. I am 174cm and about 80 kilos and the medium is close toperfect, apart from my stocky bui
D obviously restricting the tight fit around the upper back and under the arms. Still, others may not find this problem and in this instance it would be the perfect shell. 1 star short of perfect for the fit from me.

How well does the hood adjust? Can it be sinched down enough for use without a helmet?
