Ferocious in the Ferrosi.

Outdoor Research made its Women's Ferrosi Softshell Pant with lightweight, durable, and highly breathable fabric for extra comfort during your hiking and rock-climbing adventures. It's low-profile waist fits smoothly under a harness, and its tricot waistband reduces chafing as you climb. The articulated knees bend and flex easier when you're scrambling on the approach or stretching for a difficult toe hold.

Size too large

    Size Purchased: 8/Reg

Good pant, soft, but size is different from the size chart. The waist's too large for my wife. In size chart, 8 is 71cm, however, it's measured as 84cm almost..........

So happy!

I'm a girl with thighs and I was so afraid that these pants were going to have to be sent back. No chance, they fit perfect. The drawstring at the waist is really nice. I wore these pants hiking in Arches, Bryce and Zion, in and out of water, from sun, rain, and wind
they kept me comfortable every step of the way. Ordering another pair!

I am between a size 2 and 4 and the 2 fit perfectly. I loved the color (brown) and the feel. I was torn whether or not to keep them, but I was not looking for a boot cut ,so I returned them.

I loved the way these pants fit and were effortless to move in because of their stretch. I REALLY wanted to keep them but the bootcut leg was not what I was looking for. I am 5'4" 113lbs and the size 2 fit perfectly.

The Miracle Pant

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

I am 5'11", about 170, and I carry most of it around the hips. I ordered a size 12 LONG and they are the most comfortable, perfect-fitting pants I own. They are a snug fit for me, but they loosen up as you wear them, especially on the trail. The stretch is incredible and the drawstring was a great idea. The material is incredibly thin and it is not very forgiving, but I don't care, because what they lack in discretion, they make up for in comfort. They are not warm, so in the cold months I wear thick tights underneath. The waist band has a wide fabric band on the inside that disperses the pressure in such a way that doesn't give me muffin top. These pants have belt loops, a thigh pocket (along with four other zip-closure pockets, and adjustable ankle elastic. They've been very water resistant to my testing and fulfill basically every demand I have for my active pants. The only thing that leaves me disgruntled is that I only ordered one pair and I can't find them in long anywhere!

Do these pants have a UPF rating/protection?

Best Answer Responded on

The majority of OR's pants have a UPF rating of 50+. Though its not listed here, im sure these have a similar rating. No chance of getting sunburned though these pants in my experience.

Love them!

  • Familiarity: I've put it through the wringer
  • Fit: Runs large

These pants are fantastic for hiking, climbing, just about anything. I just spent two weeks on a climbing trip, and wore them everyday. My search for this type of pant is over:) The only issue I have is the size. I read reviews before I bought them regarding size and I bought a size 4, I'm 5'4 inches, 124 lbs, generally a size 6. They are definitely on the too large size and I wish I would have bought a size 2. They are still fantastic, just a bit too loose everywhere, especially the waist, but the draw string helps with that. I would recommend them.

ODR does it again!

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

I have had a few Outdoor Research products and am never disappointed. These pants were no exception. They are lightweight but feel durable. They don't ride and bunch if you are rockscrambling during your hike. I wear a size 8 and these fit perfectly. They look fantastic on! The drawstring waist is a nice addition for comfort as well.

Love the low-profile waist

I've used the ferrosi pants for climbing and hiking. I love the low profile of the belt loops and snaps at the waist. Perfect for fitting and not being irritating under a harness or backpack strap. And no elastic marks! The tricot lining also helps the waistband feel comfortable. Drawstring belt is nice for added adjustability. Quick to dry and comfortable to wear. Fit is trouser-style which I like, but has drawcord at the ankles to adjust too. An added bonus is minimal wrinkling-great for packing (and black can "dress up" for versatility). Material stretches a bit as you wear it, so I got a size smaller.

All-Occasion Pants

Finally, after looking and looking for the sort of pants that could be worn for nearly everything from shopping to climbing mountains to 12-hour flights, I found the perfect one. Comfortable, easy to care for, great looking and great fitting ~ what more could I ask for?! I ordered a second pair because I liked them so much. They're much more attractive than they look online and at a decent price. I expect these will be my go-to trousers for a long time!

The perfect pant for everything

I used to have a favorite pair of outdoor pants through Mountain Hardware, but they stopped making them. Because they were perfect for everything I like to do outside, I kept up hope and kept searching for a pair that stacked up. The Ferrosi pants meet and top my old pair!

The fit is perfect, meaning looks good and is comfortable and everything stays where it ought to. These pants are very stretchy, lightweight, wind resistant and quick to dry. Love the drawstring feature at the bottom of the pantlegs because I can switch them from a long pant to a capri while climbing or hiking without stopping. There's a thin fleece lining around the waistband, which is very comfortable underneath a harness or backpack waiste belt. The waiste sits at the perfect spot for climbing and hiking too. Plus 3, yes 3, zip pockets! I hope OR continues to make these pants for eternity because I never have to think about what pants I'm going to wear when I have the Ferrosi's around. They are my go-to pant.

Were your Mountain Hardwear pants the Petra? With the snap-up legs and the one loop on the back for a chalk bag? Mine have finally worn out and I need a replacement, but MH's new version isn't up to snuff.

These seem like an excellent pant to replace my old MH's. Glad to know I wasn't the only one left searching.

Love these pants!

The Outdoor Research Ferossi pants are perhaps the most comfortable pants I've ever owned! Great looking and ease of care in addition to their comfort make them an all-round winner. After receiving my first pair in black and seeing the quality construction on top of all the other features, I ordered a second pair in "mushroom" (great color!). I expect these will be my go-to pants from now on!

do these pants have a lining for warmth...

do these pants have a lining for warmth in colder temperatures?

Responded on

No, they do not. Only a thin layer of nylon softshell material. Great for aerobic sports year round as you can layer under them as needed. I love these pants - the men's version that is!

Great canoe tripping pants

I love these pants. I got a pair a year ago and worn them extensively on multiple canoe trips in northern Ontario and northern Scotland. Lightweight and good fitting. The material held up from major wear and tear. I highly recommend it.

Function and Comfort

If I could give it 6 stars, I would. The beauty of this pant is the stretch. Because they are a super lightweight softshell material (way too light for skiing--more for warmer weather activities), they are rugged enough to take my constant abuse, but breathable and stretchy enough to remain comfortable well into the summer. Win. There is also a great cincher at the bottom of the leg so it converts EASILY to a capris. Win. Two more words. Wrinkle resistant. Win.

Uses: Hiking, biking, climbing, travel, backpacking. I even used them running when I forgot running shorts when on a work trip and they worked GREAT.

Responded on

I like these in colder weather, too. Just add the desired base layer underneath, depending on the sport, weather and temp, and you're good to go. I really like them for cross country and ski touring, and winter trekking. The Ferrosi series (pant and jacket) is hard to beat with great breatheability and weather protection.
