Amazing pants, exactly what I wanted

Amazing Pants! I bought two pairs and have used them paddle boarding, hiking, running, cycling, bouldering, casually out and to work. The mobility of the pants is fantastic, even contorted in strange positions climbing the face of rocks they didn't give me any feeling of restriction. For paddling, I took them out early morning in the coastal waters off northern Washington in 50 degree weather before sunrise and paired them with some light long underwear. Even being wet from walking the board out, the pants still kept me warm by blocking out the wind. If you're looking for pants that are durable, functional, mobile and look good, these are a great choice.

Very comfortable pants

The pants are extremely comfortable. I like the casual look to them. The front pockets are plenty deep and the zipper side pocket is convenient. My complaint with the pants is how they are only available in 32" inseam. I got super excited when these arrived in the mail and I clipped the tags before putting them on. I'm 5"8/5"9 and the 32" inseam makes the pants too long to wear. The bottom cuff is narrow enough to where the pants won't hang down past your hiking boots, but it still leaves A LOT of fabric bunched up at the bottom near the ankles. I have to roll the pant legs and just wear them around the house because of how long they are.

Pants for everything

I've traveled through Greece and climbed the east face of Mt. Whitney in these pants. Paired with an OR button down and you'll be ready for all but the fanciest restaurants. They can handle everything without looking like a technical piece of clothing. Fabric holds up to abrasive rock, and is super lightweight. Travels well! Stretchy fabric means you may want to order a size smaller than usual. Hip pockets are on the small side, and I wish the thigh pocket zipped the other way; crashing through brush tends to open the pocket by pulling the zipper down. But if we bought pants based off of pockets we'd all be running around with cargo's from the 90's.

Comfort personified

First wear experiences are of a light weight comfortable pant that I can see becoming a regular casual item. Could run in them but I see them as being a regular hiking, dog walking, shopping, commuting pant. The 30 inch inseam is just a touch long for my micro legs but the drawstring set up neatly deals with the excess and keeps it from under my feet. Material feels tough but light, like the colour.", pockets are high on the hip but deep, swallow a phone and feel secure. Zip side and back pocket are useful. Will make a good addition to the wardrobe for travel days too. Will be looking to try the transit system ant next as a potential work trouser.

Nicest Pair of Pants I Own

These pants are incredibly comfortable, they breath great and are super light and wick moisture off fairly well. I used them first for travel through rainforests in Africa and they kept me cool, protected, and dry for two weeks. The materials and build quality are excellent. I'm a pretty small guy and I've found that most outdoor pants I've tried on have been too long or too baggy, these are great for skinnier guys and they have a hit or stretch to them so you don't feel confined. Pockets and belt loops are great. I didn't find a real use for the side pocket, but I'm sure it's great for smaller items. One of the best purchases I've made for outdoor gear!

Go back to the earlier design OR

I have ....what 6 pairs of Ferrosi pants in various colors. Why because I love the material,durability, fit, design.......well not on the latest two pairs. No rear pocket zips, I like that they made the thigh cargo zip horizontal instead of vertical now how 'bout one for the other thigh. Also don't love the change to the hem gaiter. But to top it off this particular pair of pants was the first I bought directly off the OR website and the first time I wear them to get outdoors, the fly button comes off! I decided to just process a return. Oh....and the color Curry is a fail too. Would look better if they were just blaze orange.

Great restyling... but

Love the restyled Ferrosi pants, with angled front pocket openings and leg bottoms (no more cinch cord). So, these are styled more for casual wear, for instance, the OR logo is small now and at the hip, not halfway down the leg in large letters. The right leg pocket is now parallel to the belt line, not the leg seam line. What I MISS are the zippered back pockets, which gave me a great deal of security for travel and for camping--don't have to worry about the wallet flying out. So, I'm glad that I have four other pairs with the cinch cord (can beat that for hiking) and the zippered pockets. But I will say that, for casual wear, the new styling if very sharp.

Pants that feel like shorts :)

OR makes the best fitting pants out of any company I've tried. (and I've tried a bunch of companies) The Ferrosi pants are great for warmer endeavors but work for slightly colder days as well. On the hot days, they breathe like you are almost wearing shorts. I have worn these pants on everything from desert towers, to crag sessions at the local crags (Durango area) and Many days in the mountains spring through fall. I Love these pants!!! The only issue I have seen was a rear pocket getting a hole (after a year of use) and OR had a replacement sent before the we could even send the busted pants to them! So, OR's customer service is awesome as well. Bill Grasse

Great for everything but/

Super light, stylish tighter cut but still very comfortable. Good alone on warm winter days and great over tights for xc skiing (love the sneaky drawstring) to cut wind (partially) and shed snow. Dried very fast when ice climbing in wet conditions. Can't wait to use them in summer given how light they are. I've only had the pants a couple months so hard to speak to long term durability. They dealt with a crampon snag surprisingly well / just small holes and no tear. But they have started to pill a bit on the thigh so for that I gotta take off one star and unfortunately I will soon have to demote them from 'fancy' pant status.

Very Disappointed

In 2018 I ordered 3 pair of Mens Ferrosi pants and absolutely loved them. So much so that I wore them out and needed to order some new ones. I just received 3 new pair in the email and to my disappointment OR has changed the style. Different fit, no zippers on rear pockets, no cuff drawstring but they kept they same name. If it aint broke dont fix it. OR certainly failed with this new version of the Ferossi pant. Bring back the old style or else change the name on the new...lesser quality pant that doesnt deserve the Ferossi name. Im sure they have had a lot of returns for this very reason, mine will certainly be going back!
