Why We Like The Outdoor Research Ferrosi Pant

We believe that if you can't wear your current pants up mountain peaks, on long plane rides, and to the brewery after the crag, then it's time to upgrade. And we've found that there are few better options than the Ferrosi Pants from Outdoor Research. Not only does the lightweight nature of these pants make it an easy choice for light-and-fast movement in the mountains, but it also prevents lingering moisture from clinging close to your body for hours on end. Accidentally tip your canoe? No worries, the Ferrosi pants dry up and get the adventure back on track in no time.

Customer Images

Here's what customers have to say

The pants are generally well-liked for hiking and outdoor activities, praised for being lightweight, comfortable, stretchy, and breathable. They are described as great for warm weather use, with quick-drying and moisture-wicking properties. However, some customers have experienced quality and durability issues, with the pants snagging or developing holes after relatively light use. There are also comments about inconsistent sizing. Overall, the pants seem to be a good option for warm weather outdoor activities, but the quality and fit may vary.

Go To Pants

I love these pants, have repurchased many times. They’re super breathable, quick dry, flexible and flattering. They will snag and pill a bit, but that is typical of quick dry fabrics I find. I would love to see more bright colours available. The tapenade yellow that was sold years ago would be great.

Light weight. Fits perfectly.

These pants have deep front pockets. My cell phone doesn't fall out!

Lightweight & comfy!

Material is super thin — breathable on those hot days. Runs a little large in the waist, but it has like a built in tie if you don’t want to wear a belt. I wish they had a tall option, because at 5’10”, I am flooding in these pants. I would still buy again despite that. So comfy!

Feels great, need more tall sizes

Have had these pants for about a year. Feel is great, and finally a pair of women’s hiking pants with a back pocket. However, they do loosen up after washing, and I wear a 16 tall which only comes in black, or the light sand color. Can we get some other colors in tall/larger sizes please?

Are These The Perfect Pants

I had a pair of these about 5 years ago when I walked the Camino in Spain. After walking, I backpackad throughout Europe for the next 12 months. These were my only pants. They are durable, lightweight, breathable, dry fast and I loved them for all of that plus the zippered pocket that kept my wallet and passport safe in Paris when two friends had theirs stolen. The majority of the time I hand washed them since an actual washing machine was wishful thinking. Fortunately, they don't hold onto sweat and stink like some man-made fabrics so a sink, some warm water, a little bit of soap, and some elbow grease kept me from being too socially unacceptable. Did they pill? Yes, between the thighs. So what. The zippers held, no seams unraveled, the front button didn't pop when I first wore them and was too fat for them and the drawstring was a lifesaver when they were too loose when I finished. Ladies, these are a perfect pant. I just bought a new pair. It's the right time. Adventure awaits!

My favorite pants

Love these. I have two pairs in different colors. I get many compliments on them while hiking. They are comfortable and the waist height is perfect. Love the side zipper pocket AND the back zipper pocket. For sizing, I am 5'4" and a muscular 130 pounds, and the size 4 fits me well. I hike frequently in the Grand Canyon and these pants have withstood at least 4 hikes in there so far. I am also a climber.

Comfortable stretch, convenient pockets

These pants are very comfortable. The waist is soft and the drawstring convenient for when the fabric loosens up or I lose a little weight. The pockets have good depth. It's nice to have a drop-in cargo pocket with zipper. Yes, it fits a phone. That quick access is nice for phone photography. The legs are straight and not too narrow. The reason I gave one less star is that -for better or worse- the fabric loosens up a bit with wear between washes.
