Ferrosi Pant

If you can't wear your current pants to mountain peaks, on long plane rides, and to the brewery after the crag, then it's time to upgrade to the Ferrosi Pant from Outdoor Research. Not only does the lightweight nature of the pant make it an easy choice for light-and-fast movement in the mountains, it also prevents lingering moisture from clinging close to your body for hours on end. Accidentally tip your canoe? No worries, the Ferrosi's will be dry in no time.

The all-around performance of the Ferrosi have made them a top-seller for Outdoor Research and a staple for every outdoor woman's closet-in fact, you might even want a pair in every color. At only 9.5oz, they're the perfect addition to long backpacking trips and the cinch at the cuff makes them versatile for days on the trail that start cool and hit 70 by early afternoon.

  • The perfect technical pant for, well, everything
  • Cinch closure at cuff eases transition for temperature variable days
  • Ripstop nylon protects from sharp twig ends while bushwacking
  • Cargo pocket secures valuables at the crag or on the train platform
  • Material make-up dries quickly after river crossings or canoe mishaps
  • Harness compatible waist for long multi-pitch days
  • Item #ODR00V6

A tough pant but with a few key design flaws! I wear these pants A LOT for work and play but I wish the design was a little more flattering. Yes, the fabric will 100% pill from abrasion, but that never bothered me much. A zippered thigh pocket is nice but falls short of being large enough for a phone. On the bright side, the OR Ferrosi's have a drawstring cuff for cinching the ankles, which is clutch when summer heat approaches. The biggest con to the design and fabric choice is that the calf and ankle cut is too wide. The movement-mirroring fabric tends to sag out a lot on the lower legs and tend to have a permanent bell-bottom look instead of the more sleek, tapered cut that the Men's Ferrosi pants showcase. When hiking or climbing outdoors, the saggy material gets caught on brush or stumps. Even worse, when it's warm out, the baggy and oversized material traps heat at the calves causing discomfort instead of breathability. Another key design flaw is that the back pockets tend to fail instantly due to the stitching design. Instead of individual pockets with a bit of extra material, these are sown directly to pant material. Meaning that instead of saving weight, the first time you climb into a wide chimney or scoot on your bottom to rig a rappel on some desert tower, boom, the stitching blows out and you have two useless back pockets. Mine lasted two full days before I destroyed them climbing. While on the fourth pitch of a big line in Red Rocks, my ID and credit card fell out of my back pocket that unknowingly failed due to the stitching design. Luckily, they were trapped in the cuffed ankle and I managed to snatch them before they took a bigger ride. I saw the men's version of these and they look way better and I might just order those the next go around.

I just received these pants and think they look and feel really great. I’m exchanging them for one or maybe even two sizes up from normal though. Second pair of OR pants I’ve bought and I had the same problem before. Got to remember to size up for the future because OR pants are awesome!

I Put on these pants and liked the feel and fit immediately. The only exception was a little gap In the waist area Nothing a belt wouldn’t fix. Luckily I noticed the internal draw cinch to adjust the waist area! Such a solid pair of pants. Also have upf 50!! Cannot wait to try these out fishing in the keys soon. A definite must.

I normally am a 4 or 6 (in Prana hiking pants, I'm a 6). I bought the 4 and 6 to try on, and they're both too small. And also, too short. :( I just returned and exchanged for an 8; am hoping that fits and is also long enough. (I'll update this when I receive them.) I'm 5'9", so I'm tall but not crazy tall. The material is great, really lightweight and stretchy. Hoping to take these on a hiking trip in South Africa. O.R., please consider making in a long!

Outdoor Research Ferrosi Pant - Women's 4 These pants are super comfortable and stretchy. I wore them on a 10 mile Utah alpine hike in October. They kept my legs nice and warm, while staying dry and breathable. Because of their stretch, they would probably also be good for climbing. I highly recommend these pants!

I got the chance to try these, and had to have them. I'm not just saying that! I seriously never wanted to give them back. What can I say that 30+ great reviews haven't? First of all, as a taller woman with wider hips, finding adequate pants is a challenge on its own. These fit beautifully and so comfortably! I was impressed with the quality and the material - it seems super durable and strong. I first took them on a long alpine hike to bag a tall peak, glissaded in the snow on my butt, and scrambled on rock on my butt, and they showed no signs of wear and tear. Any water I got on them beaded off beautifully. Most importantly, they let me move and do my thing! I climb, lunge, high step, run, walk, and scramble in them with ease of movement. I don't think about the pants at all, which is what I want. They make great rock climbing pants too. The side pocket is sleek, yet functional with a zipped up pocket, and there is also an internal lace system to cinch them up. All in all, the best pants I ever had for active wear!

I've owned 4 pairs of Ferrosi pants and they c r u s h. Great for warm days on the glacier, any weather whilst hiking, and all climbing. For glacier / snow travel, they don't hold up well to crampons (I've put a hole through a pair with mine), but boy do they breathe well & protect from the sun on those hot glacier days - personal pro-tip - sitting in the snow to cool off, but having the pants dry off quickly!. For climbing, they've held up to the rock pretty well with some minor pilling over a few months, but *never* any holes, no matter how many slips n falls I've taken. That said, I have been on the search for explicit "rock pants" so I can keep the life in my ferrosi's longer. For hiking/backpacking, they hold up great over multiple days. I've worn them up to 4 days in a row (in the summer!) with comfort. They do tend to stretch out a bit over a few days, but this doesn't affect their functionality. All in all, these are my #1 for multisport trips and activities.

My girlfriend tried these out and had some feedback to share (they also look great on her): "These pants are good for chilly days if you are planning on being active and are light enough for warmer days as well. Lots of give in the thighs and a comfortable waistband. Haven't tried it, but they would probably be compatible with a thin baselayer underneath for extra warmth."

I gave these pants as a gift. They run true to size. She usually wears a size 4 and a size 4 worked well for her. These pants are lightweight, comfortable, stretchy, and durable. They are breathable for warm days but also block wind and are water resistant for the chilly days. They are great for hiking, rock climbing, yoga, and whatever else you desire to use them for. They dry fast and block the sun. I would highly recommend this product.

I got these pants for my girlfriend and she really likes them. She has a pair of the Ferrosi convertible pants, but says she likes these better because the zipper on the leg can be a little bit annoying. She likes how much stretch there is to them as it makes climbing and hiking more comfortable and less restrictive. Great pants!

These are everything I wanted in a pant for back country skiing, perfect in every way except too long! I can remedy some of that by shortening them from adding a seam across the thighs, but given the crotch gusset and darts for the knees, I could only take out 2 inches (I used to sew for Marmot Mt Works back in the day, so I have skills here). I need another 2 inches out of the length but with a zipper at the cuff, there isn't anything else I can do so I just roll them up when I don't have my ski boots on. OR needs to make a petite version and they'd sell a ton of these!

We make them!! 29" inseam! If Backcountry doesn't have them in stock, go to www.outdoorresearch.com! Thank you, Leta OR Rep

I love these pants and own 6 pairs. I have worn them hiking, backpacking, rock climbing, and around town from Alaska to Texas over the last 4+ years. These pants are lightweight and have enough stretch to heel hook or high step your way to wherever you are going. The material is wind resistant and water resistant, but these features aren't as effective after a while (but I'm talking serious wear and washing over a 2+ years). I have worn these in 100+ down to 10 degree weather. That being said, these pants don't hold up if it is too cold even with a base layer, but I would say these are solid at 50 degrees or above without a base layer and 30-50 with a light base layer (full disclosure I live in a hot climate so others may have a better tolerance). I also like that while the legs will stretch a bit when you hike, the waist does not, which is a huge plus for me. I do wish they came in a short length, but the draw string at the bottom lets me shorten them when needed. As for fit: I have a small waist and larger hips and these fit great with no gaping at the back.

I'm short, and fairly straight in terms of my body type. I put these one and expected the 6+ inches of extra fabric at the hem. But, starting mid thigh these just balloon outwards. I could probably fit 2 of my calves at least in the pants where they hit. Super weird, super unflattering. The cinchy part at the bottom becomes useless. Overall, unless there's like an X-short size, these won't work. Returned.

I've worn these hiking the hills on cool 40 degree days and worn them under rain pants for field work. I love that the fabric doesn't chafe or restrict movement. Even when damp when worn under a rain pants they are still comfortable to wear and dry fairly quickly once the rain pants come off. The fleece waist band is very comfortable and enhances the fit. I'm not thrilled about the cotton external drawstring but it works well enough. I'm seriously thinking of buying another pair of these and getting rid of all the other synthetic field pants I have!

I have two pairs of these pants now, and they are my go to for climbing, hiking, outdoor excursions. Nice stretch, can add a base layer underneath, zippered pockets, and the drawstring at the ankle makes these the best all around adventure pant I've ever owned. You definitely want these!

I needed some more fall and winter hiking pants, so I bought 2 pairs of the Ferrosi pants because I knew how great the fabric felt and how well the Ferossi line overall performed. These fit true to size to slightly large and run long. There is no short or long inseam to choose from, so I had to get a regular. I am 5'4 and the regular was too long. The Ferrosi pants thankfully have a drawcord hem in the bottom to cinch them and keep them from dragging the ground. They have performed really well so far this fall, as I have hiked in them in 40 degree weather and in some rain. They stayed dry in a light rain shower and were very breathable. The Ferrosi pants would also be great for climbing because they are very stretchy and abrasion-resistant.

Bought a pair of these online without trying them on and absolutely LOVED them for hiking in the Dolomites in Italy. The pants fit loosely, allowing for long underwear in cooler temps. A side pocket on the left thigh for my smartphone allowed quick access for photos. The waist has two snaps (better than buttons) and can be drawn tighter with strings. I wore these pants for all but one day hiking, and simply washed them in the sink as needed. Once home, I reached for these OR pants as a go-to comfortable pair of pants for life in Boise.

Last year, I purchased the OR Ferossi shorts in a size 4 and fell in love. The material is water resistant, rugged, and I got a lot of great wear out of them. Naturally, my next train of thought was to grab the pants in the same style. I was sure I would fall in love just as deeply. I couldn't be more wrong. The sizing was a definite issue. Whereas the shorts provided a little room in the hips, these completely slid over my butt with the button fastened and the cord tied. I doubt I would be a 2 and quite frankly, I'd rather just return the pants. I don't know if I received a fluke product, but these will be going back. I still love OR, but these pants are not for me. Pro-Tip: grab two sizes to save yourself some time & return the one that doesn't fit. These pants are worth a shot, but the sizing isn't consistent.

RAD PANTS! Please make a 16??

They were stretchy enough to zip, but too tight to keep. I wear a 14 or 16 depending on the brand, often a W because: Junk-in-the-trunk. So I tried the 14, and I can tell they are cut for an active use, which is AWESOME. The stretch in the fabric is incredible, and overall fit/cut is much more modern than so many other high-waisted-diaper-looking pants. The rise is a little lower, the waist band made to be perfectly flattering standing or bending, and cut with enough give for ladies with a little extra junk and/or muscle in the thighs and butt. I also like that they aren't baggy in the crotch because that generally leads to unnecessary chaffing while hiking. I just wish they made a 16. The search continues.... hard to say if they run true to size since the chart only goes to 12. For reference my hips are about 45 and natural waist about 33, and the 14 was a bit too small.

What is the pants rise?

Hey Dixie! Great question! They are a mid rise pant.

Hey Dixie, Jules is spot on: Mid rise on the Ferrosi. GREAT fit. I own several pairs including the pant, capris and shorts! Thank you for the question! Leta OR Rep
