The Orion doesn't put up with lip.

Marmot crafted the Men's Orion Softshell Pant for those who put their pants through hell and need something a little tougher for burly approaches or rugged ascents. M3 Softshell material shrugs off abrasion and light precipitation, stretches, and breathes. Backpackers and mountain travelers can finally turn to technical fabrics without giving up comfort and durability.
  • Highly breathable M3 Softshell material allows sweaty vapor to escape from beneath so you don't feel clammy
  • Softshell material allows for ample stretch and has a durable face so it won't tear when you're on the rock or trail
  • Articulated knees for scrambling through boulder fields or up a rocky face
  • Removable webbing belt features an ultra-thin buckle that won't dig into your waist when you're wearing a pack
  • Item #MAR2333

Best pant for the backcountry.

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: small

I've owned these for a few years now and have definitely put them through the wringer. From mountaineering in the rockies, from Colorado to Jasper and up to Alaska. Kayaking in the pacific northwest, trekking through berry brambles, multi pitch trad climbing in yosemite and on cross country hiking through the trinity alp these are as good as new and still the burliest pair of pants i own. I have patagonia simple guides (amazing pant as well), but these are warmer and stretchier. Now for the other side, they are more like tights than pants... or somewhere in-between- a formfitting pant. Keeps me warm and more mobile than i am. Great expedition pant in temperate temps and rugged terrain. They don't smell to bad after two weeks in the bush; at least i don't think so...

Alaska-tried, bombproof, ass looks great

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I wore these babies for the entirety of a 24 day mountaineering course in the Chugach Range of Alaska and 25 backpacking in the Healy Mountains.

I walked through heavier schwack than I ever could have imagined in them and they held up with absolutely no snags and no pilling. The only rip/tear came from taking a tumble on moraine while carrying about 150 lbs worth of weight on top of my own (two backpacks, trying to be a hero, don't ask). And it's a tiny one in the conveniently reinforced knee easily patched with some dental floss sewing work.

They were breathable even on the hottest days and manageable around camp until nighttime mandated the puffy pants anyways. As a guy who can't stand walking around with excess, baggy cloth around my legs their fit was perfect (6'1", 180). Snug, but with plenty of stretchiness and no inhibition of the range of movement. Going from these to jeans in the front country was a rude awakening concerning the limiting capability of denim. And, my girlfriend likes the way they make my butt look. So there's that.

They do however possess an unfortunate shortage of pockets. (the only reason I dropped them to four stars) The two front pockets are great--zippered and fleece lined for added warmth-- but the lack of back and/or side pockets was unfortunate for storing things like compass, maps, snacks, etc.

Skinny legged dudes rejoice!

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

I've got skinny legs. Always have had, always will have, just the way I'm put together. These pants are a revelation - fit like a glove with just the right amount of stretch, very comfortable under a harness, and wide enough at the bottom to fit over my Scarpa Triolet pro's. I would marry these pants if I could.

Best mountaineer pants I've tried. Trim fit tapered, still fit over Baruntse boots. Perfect weight for high output. Zippered pockets. Would love a back pocket or leg pocket as well. Went up Rainier last June with these bad boys.

Chicken Legs, Yes...Skier's Legs, No

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

I agree with the reviews below on the fit and feel of the pants. If you have skier's legs, as opposed to "chicken legs" like Derek below, then these pants are too tight, at least for me -- not uncomfortable, just perfect if you are going to be in Jimmy Fallon's next "Tight Pants" sketch. I'm 6'1", 33" waist, 195 lbs. I sent them back. I do have the Marmot Scree Softshell and they fit well but are on the baggy side. If Marmot would make a pant that is between the Scree and Orion cut, they'd have it dialed for guys with skier's thighs. I still give 5 stars b/c the pants were unquestionably well-made and designed and I have no doubt they would perform and hold up as well as my other Marmot gear.

Thanks for the review. We're built about the same so this was helpful. I had the same issue with the Scree. They did nail it with the Rockstar but they discontinued them. Guess I'll just need to keep buying Tenacious Tape to keep the Rockstars alive because I'm sold on the M3 fabric. Thanks dude.

My favorite pants, except in summer

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Best pants I own. Quite slim fitting which I love for hiking and ice climbing, doesnt get snagged on branches or crampons etc. Also quite warm despite relatively light weight. Nice fleecy feel inside too, with well placed pockets. Too warm for summer or warmer weather. Have my Marmot Rockstars for that weather and they are equally awesome.

Handled the Grand, trailhead to summit.

My first adventure with Mammut's Orion Softshell Pant was up the Grand Teton's Upper Exum. We attempted a day trip from the trailhead's parking lot to the summit, and these pants were the perfect choice. They were warm enough when we left at dawn, and they stayed breathable once the day warmed up. The Grand was very windy and cold that day, and these pants kept me comfortable throughout. The Orion is really stretchy, allowing a full range of motion despite its slim fit. The slim design is great for chicken-leg climbers like myself. Mammut reinforced the Orion in all the right places; I'm super excited to wear these throughout fall and winter down south.

Orion is a winner! True to size.

Weight of the 34" is 398 grams. I am 6' tall, athletic body type, weigh 172lbs and wear 34" jeans, the 34" Orion fits like it was made for me. This is a winner! Stretchy, water proof, light. For warmth I will wear an Icebreaker woollen pants under it, should be nice. The belt is surprisingly good.

AWESOME pants!!

  • Familiarity: I've used it several times

I've used the Marmot Orions for about 7 months now for mostly backcountry hiking and some mild climbing. This pant excels for the following features:

1. Fit - like everyone has said, they are extremely well-contoured. I like that there are no back pockets which is really useful for avoiding zipper annoyances against your pack. The pockets can a bit tight because of the fit and you while you might forget you have them on, you'll definitely FEEL a phone, key, energy bar etc. in it because of the tight feel. The pockets themselves are lined and super comfortable and warm!

2. Features - Marmot's M3 softshell feels a little coarse against the thigh, but is VERY breathable. It sheds snow immediately and a light drizzle is nothing (you will get wet in a shower), but from being completely wet, the pant dries in a few hours. Reinforced areas on the back, knees, and ankles are nice but I think the M3 material itself is strong enough that I doubt the pant would suffer without the reinforcement. Nonetheless, it's held up to climbing well.

3. Maintenence - I've used Grangers wash/powdered detergent. The pant looks entirely new. I do wash the pant inside out to avoid the zippers snagging and I do close up the pockets. I've washed it about 6-7 times (~once a month). I'm not sure what the issue is with other users finding the material not lasting (maybe a top-loading washer or something?).

4. Price - I'm definitely not saying the pant is not worth it, but it's hard to say because literally NO OTHER COMPANY has come close to making a pant like this. I'm not sure, even after several months, why other companies haven't caught on because I think there's a strong need for this type of product! I think the $144.95 is a little pricey, but I've also seen it on sales for below a $100. I'd easily buy again.

Lastly, the black color pant's reinforced areas are the same color (so it just looks like a black pair of pants). The other colors have the reinforcement showing - just a minor detail.

Sleek Pants for Lean Hikers

  • Familiarity: I've used it several times
  • Fit: True to size

Baggy-butted, flappy-legged pants are apparently the style these days. I'm sick of them. They feel cumbersome, especially when adorned with absurd cargo pockets. And they look ridiculous. Every manufacturer makes them. Marmot is one of the few companies I've found that makes sleek pants for lean hikers. These pants stretch well and dry very fast. I refuse to wear hiking pants that have belt loops but no belt, because it's difficult to find the ideal belt, and even then, the belt stays up, the pants slide down and under, and your comfort is compromised. Integral belts work perfectly, and that's another feature I appreciate about the Orions. My rating: 6 stars. One extra star goes to Marmot, for bucking a wrong-headed but pervasive trend, and instead letting function guide the design process. By the way, I'm 6 ft tall, 175 lbs, with a 33-in waist, and the size-32-waist Orions fit like they were tailored for me.

Best Pants Ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size

I have spent years searching in vain for a hiking pant that was technical in performance and yet didn't make me look and feel like I was wearing a parachute. Then I found the Orion. These pants fit snug the whole way down my leg but the 4-way stretch material from Marmot has allowed me to climb, run, scramble, and hike without any restriction. I actually have a better range of motion in these pants than in any others I've had before (Stoic, Mountain Hardware, TNF).

I'm 6'1", 160. I got the 32 and they fit almost perfect (a little big in the waist but a good belt fixes that). When its hot I just roll em up to the knee and rock the manpri look. I plan on getting multiple pairs of these pants. Great product from Marmot!

All around Best

  • Familiarity: I've used it several times

These are the deal. They fit like hiking pants should. not tight, not loose and blowing in the breeze. They feel great and have great flexibility. Perfect for fall and winter hikes.

All around Best

perfect pant for just about anything

    These are the best pants I have ever tried. However, keep in mind that they are a very athletic fit, if you want them to be a bit looser size up. They fit close to the skin but are extremely comfortable, I forget I am wearing them when I have them on. They are conveniently water resistant and extremely breathable and sweat wicking. I haven't tested them in high speed winds but they are resistant to mild winds and don't blow around and billow out because they fit so well. The reinforcement around the knees and ankles is well thought out and will surely increase the life of the pant. The pockets are terry cloth lined and are perfect for hand warming. The waist is very adjustable with elastic, a belt, and a velcro snap and zipper. Overall this is a perfect pant for most any activity from lounging to high output adventure sports and climbing.

    Marmot Orion Soft Shell Pant

    Miles Smart, Professional Mountain Guide and Marmot Athlete, reviews the Marmot Orien Pant. Learn more about Miles and the Marmot Athlete Team at

    You mention spring ski - will they hold up to the pow-pow at Snowbird in April? I use a feature-free thin Gortex soft shell over base insulators and I am looking for a nice pant that will be warm enough for spring skiing sans the bulk of a ski pant and double as something I can hike the Fourteeners in after the melt is on.

    You might want to go with an M1 pant from marmot. These aren't going to be extremely warm for your purposes. You could get away with a VERY warm baselayer (we're talking a heavy-weight one) with the shell over base insulation. I'd be careful on sizing with these too because they're going to be a tight fit with 2 layers under you for sure.

    As for the snow shedding capability, these can take it, but you'll be drier with an M1.
