Here's what others have to say...

Can somebody help me with sizing? I purchased...

Can somebody help me with sizing? I purchased a medium Halogen Hoody and I was swimming in it. Generally I wear a medium everything but now i"m thrown off. I am 5'9", 145, 39-40" chest. Am I going to be constricted by a small? Or swim in a medium?

Best Answer Responded on

I am a similar body size and find that I fit well into the OR small jackets. Unfortunately, we no longer have the Outdoor Research Mentor jacket available. I believe the small should fit just fine, but if you'd like a bit of extra space of layering the medium should work well for your outer layer and use small OR baselayers. If your looking for a similar jacket offering superior weather protection with more of a skiing and mountaineering mindset, check out the OR Vanguard:

Also, the OR Axiom offers great weather protection with a lighter mindest and more designed as a technical climbing shell, check it out:

Anyone had a chance to compare Mentor with the Norr�na Trollveggen Gore Tex Pro. I had the Trollveggen on in the shop and the zippers were almost enough alone to get to buy it over the Alpha or Beta Bird. Any thoughts

One of my favorites

I'm 6'1" 185lbs and the large is a great fit. Plenty of room for layering, I can even stuff a stout puffy underneath if needed.

This is one of my favorite outerwear pieces. I use it primarily for resort and backcountry skiing in inclement weather. Well thought out design and terrific fit and finish. Hood just fits over my ski helmet. No worries about how well the fabric breathes since you can vent this thing to the extreme. Pretty darn lightweight for the protection level -- I ended up having to shop around quite a bit to find a rain shell light enough to justify packing for warmer trips instead of my Mentor.

I also tried out the OR Maximus jacket, but unless you're going to seriously beat on a jacket, why take the extra bit of weight? This jacket is plenty burly.

A pretty good value at regular price. On sale, it's an unbelievable value.

Almost perfect

Sweet jacket that can be found online these days at a great price for as low as $219 - $230. Rugged as heck. Features are just about perfect... not too many features and not too few. Side zips are great!

The hood is ridiculously huge. Even with a climbing helmet on, it is a floppy bag on my head.

Also, I would lengthen the cut a little bit more in the back, but this is a small detail.

A phenomenal jacket

I really cannot recommend this jacket enough.

Being a Goretex proshell I won't dwell too much on the material, its been discussed to death (and clearly regarded very well).

The fit of the jacket is very good; I bought a medium and I am 6' 160 with an athletic build, longish arms and a longish torso. My buddy bought one two years ago and it fit like a poncho with skinny arm holes. But no more! (So make sure you check the review date when you're shopping around.) The fit isn't super athletic, its a little bigger than the Mammut Nordwand, but its somewhat more athletic than the Arcteryx alpha SV or theta AR. I think its a very good in between. It is good to put some layers under (I've had the mont-bell thermwrap parka, and a few wool long sleeves under and it felt good, room for a little more). I also like the cut of the hood, plenty big to get over a helmet, but it can be positioned so its not ridiculous without.

The pockets are well placed and there are a couple of little pockets inside up high for an ipod, a gu or the like.

The build quality is also amazing (even though it was made in china). I couldn't find a defect. The seams are great, and the corners are reinforced.

A few little gripes: I don't really like the velcro on the wrist cuffs (its fine, just not great), I'd like a water bottle pocket and the pit zips to the waist seem kindve unnecessary (but don't really take anything away).

I owned an OR Foray shell and it fit great...

I owned an OR Foray shell and it fit great for a summer/late spring/early fall weight rain shell (i.e. no heavy layering) - I had the XL and don't think with my build I want an XL in the Mentor. I am 6'2, 250 - put some pounds on lately in the gut but have broad shoulders and chest.

I plan on using this as a ski jacket and spend my time in the north east and as a three season shell (late fall, winter and early spring. I need something I can layer underneath and think the XXL is the way to go.

I would plan on wearing a heavy weight fleece with heavy base layers or a down sweater wight base layers.

Should I go for the XL or XXL? I am 90% leaning towards the XXL

Responded on

Their sizes run large in this jacket. The XL will mostly likely fit well.

Solid fit, kinda general. Great feature, the torsoflow vent is AMAZING. I got the large for layering purposes but already want a medium for when it warms up but stays wet. Not to mention the manufacturers guarantee beats most out there!
The hood rolls can be rolled down to free your movements and two way front zipper makes adjusting a harness a breeze. If you're on the fence about a pro shell\ rain jacket. Make it this one.

Bought the yello/grey on sale....

I will say it's a beautiful jacket, very very well built, substantial feel & heft to this shell.
Unfortunately the XXL fits far too small....particularly the arms and shoulders....whats up with that??
I'm sending it back....i think i'm going to cry. :)
If you are a bigger guy, i'm 6'4" and 265-270, i would stay away from this shell.

Why is this jacket so much cheaper than the rest of the pro shells? makes me question performance and durability..

Responded on

Hey Evan, I wouldn't use that as a determiner for durability... it still falls into the $400+ range... its just on sale!

Responded on

Evan, OR overbuilds its products, and then backs them with an "Infinite Guaranty," which no other vendor does. It's full Gore ProShell, 40D body and 70D shoulders for added durability. I own one. It is awesome. I LOVE the "torsoflo" concept which opens up the jacket to vent either from the hem or from the pit, giving your heat a very easy place to dump.

This is a SCREAMING DEAL because its last year's color and they want to move it out. You should snag it before everyone else does!

Really, the question to ask is why other companies are charging so much for Pro Shells! OR gear is well designed and bomber, at way better prices then their competitors. Also it is backed with "Infinite Guaranty". Swoop this deal while it lasts!

How well does the hood on the mentor adjust? I currently have an dead-bird Alpha LT and I'm not really happy with it, but the reviews for the mentor make me want to give it a try.

Responded on

Hey Ian, the hood goes right where you want it. Adjustment on the back crown of your head, and two adjustments at your jawline. You will NOT be disappointed. I promise you!

Step Aside, Arc'teryx

I'll echo Aaron Nash's review 100%. This jacket has never disappointed me and in my opinion it rivals the competing Gore-Tex Pro Shell jackets (the bird fossil brand in particular). Here have been my experiences:

Skiing: this is my primary ski shell and it has held up to abrasive snow and ice (I am new, so I fall occasionally) and looked brand new after the first season. It keeps the wind out well too, but also lets me dump heat in a hurry so I can avoid sweating on the way down and freezing on the lift back up.
Mountaineering: I climbed Longs Peak with the Mentor in rain and sleet. I was 100% dry and it showed no wear after rubbing on lots of granite while scrambling up and down.
Hunting: I just got back from a hunting trip where it rained non stop and we were bushwhacking through wet brush and shrubs. Again, 100% dry and no wear and tear despite being scraped against trees and branches. Washed it with some Nixwax and it looks brand new.

When I went searching for a Pro-Shell jacket, I basically narrowed it down to the Mentor or the 'teryx Alpha. From there, the decision was cake. What sets the Mentor apart? First, the Mentor wins this easily in terms of ventilation with the torso zips. You'll never get clammy in this thing. The Alpha can't compete in this regard. Second, the Mentor has a two-way main zipper which is great for dialing in the perfect fit. This is just my personal preference, but I gotta have this with my jackets if possible. Third is the main advantage the Mentor has: price. The mentor costs hundreds less than other Pro Shell jackets, yet it is built just as tough, has a lifetime warranty, superior ventilation, and attention to detail.

In my opinion, if you spend the extra one or two hundred bucks for an Alpha AR or SV, you're a sucker. That extra money buys you a less-thought-out jacket with a well-recognized brand logo and that's it. I now consider Outdoor Research to be a top-notch brand with some very innovative products that in my experience are all built solid. If you want a Gore-Tex Pro Shell, this is hands down the best value.

I am 5'11" and weigh 185-200 lbs (depending on the season). The L is perfect for me. Plenty of room for some layers and a down puffy, but not overkill.

When the Zombie apocalypse comes, I'll be happy I have this bad boy, and also happy with the additional $100-$200 worth of gear that the Arc'teryx-wearing fellas couldn't afford. Buy hey, at least they'll be wearing a fancy brand name when they get eaten by zombies.

Does the Mentor have a powder skirt?

Does the Mentor have a powder skirt?

Responded on

No the OR Mentor Jacket is a lightweight shell made for climbing and aerobic activities. Look in the ski jacket product group for jackets with powder skirts.

Responded on

I am actually looking for something to use for both backcountry snowboarding and winter mountaineering. An optional powder skirt (zip out) is something I have found in other similar jackets I am looking at, like the Marmot Alpinist and Arcteryx Stinger. The Mentor is a less expensive Gore-tex Pro option. It looks like a lot of people here have purchased it with skiing in mind. That looks promising...

Hi. I,m 190 lbs and 6'2". My chest is about 41". What size would be better for me? I've tried OR's Helium jacket (Large) and it was a little tight for me with fleece layer. The jacket is supposet to be used mostly in winter with 1 or 1,5 layers of fleece. Thank you.

Responded on

I think a large will work! My brother is 6'2 185lbs and he fits a large with layers underneath....

Responded on

The only thing about the Mentor Jacket is that it is a trim fit, so it fits closer to the body. If the Helium was a little snug in a Large, then try the XL. If it is too bigm the folks at are the best at swapping things out so you get just what you need.

I'm looking for an absolute BOMBproof shell...

I'm looking for an absolute BOMBproof shell that can be very cool on hot humid days. I do field work regularly in dense undergrowth and am still trying to find the perfect jacket that keeps me as cool as possible but will also live up to tons of abuse. Any recommendations? Is this jacket good in really hot jungle-comparable weather?

Responded on

Wow! Tall order! The more bombproof you want it, the more dense the fabric - ie hotter than you are talking about. You need it waterpoof? The Mentor is 40denier and 70 denier face fabric with Gore ProShell laminate, while the Furio Jacket from OR is all 70 Denier (D) face fabric with Gore PacLite. The lightest Gore version from OR would be the Foray Jacket, Gore PacLite with a 40 D face fabric. So tell me more about your needs, but hard to have "cool" and "durable." By the way, all three of these jackets have side zips for torso-flow, which will help to dump heat quickly. An OR - exclusive feature!

Pro Product for Less

My Mentor jacket has been with me on top of every major peak I've summitted and every line I've skiied in the past two years. This is a workhorse jacket that will not leave you disappointed...or wet.

Regarding fit, I'm 5'9", 175 with broader shoulders and the medium works great for me. There's enough room for my base, wool midweight and down jacket underneath. The fit is close, but I don't want a big baggy jacket when I'm in the alpine.

Ventilation is great with pit zips that lead all the way down to the bottom of the jacket. All 3 exterior pockets are mesh as well, so opening them will give you added ventilation. Proshell doesn't breath very well (if at all) but it's fine if you vent the coat properly.

Waterproofness has been spot on. No complaints whatsoever.

The jacket is extremely durable. I've put this thing through some major abuse and it just keeps on doing it's thing.

The price on this jacket makes it a no-brainer. Much cheaper than some other companies who use dead birds as a logo, and the same quality. OR also backs their gear with a lifetime warranty. If something goes south with your jacket, call them up and they'll replace it for free, or refund your money, no questions asked (I've been through this process twice and the guys at OR are top notch and very friendly). If you want a quality jacket that will protect you when it's nuking, last for years, and cost less, get the Mentor.

If I can get a great deal on this, would this work well enough as far as breathability for active summer activity such as road biking, or is Pro Shell the wrong material for use like this. I'm looking for a jacket I can use in the summer for biking and hiking, but also a good shell for layering when it gets colder.

Best Answer Responded on

This is a great jacket....but it is better suited for ski touring, ski mountaineering,mountaineering,cold wet and snowy Alpine environments....

I live in the wet,rainy coast of British Columbia, so I do on occasion use this jacket for very wet bike commutes...

Responded on

It will definitely work as a good shell layer. It doesn't breath as well as other materials or a 1-2L coat, but the venting options are very nice on it to keep you cool.
I use it as my primary alpine climbing/skiing jacket all year round, and while a little warm in the summer, it keeps me dry.

How does this jacket compare to the arc'teryx...

How does this jacket compare to the arc'teryx alpha SV? Does anyone have experience with both? Which do you prefer? What do you dislike about each?

Responded on

I prefer this one. The alpha is built very, very baggy. You could wear two of your largest puffies underneath. The Mentor is a bit trimmer, but still big enough to layer.

The thing I liked best about the alpha SV was the hood, and the functionality of the Mentor is very similar.

Otherwise, they are both proshell, burly coats that will do what will do what they need to do when the wind picks up and the crud starts falling.

And that leads us to the final point: price. I bet you can think of something fun to do with that $180 price difference.
