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.

Size

Super breathable, great fabric and color options but really only a summer pant. Not super season-universal. Also they don’t have my size, so I had to size up so it’s slightly big on me.

My wife's favorite pants.

My wife lives these pants. I get her a couple pairs in different colors. She's a teacher and always gets compliments when she ears them. I have many pairs as well. I hiked the PCT last year with a Ferrosi convertible pants, so I can attest to their comfort and durability. They stretch nicely. They breath very well. They're soft and they look good. If you've never tried anything from the Ferrosi line, do yourself a favor. You can't go wrong whether you choose pants, jacket, or pullover.

Fav backpacking pants for years

I love these for backpacking and hiking. They are lightweight, stretchy, but durable and hold up well against brush. I’ve been backpacking for 10 years and have tried many pants and these are my favorite. The range in lengths is super awesome.

OR Ferrosi Pants Great Style and Functionality

They are super comfortable and they fit great. Very flattering. They are comfortable to wear now in the hot Texas heat. I plan to layer tights under them next month while in chilly Vermont if needed. They take up little space in my luggage and are versatile enough to wear hiking, climbing, out to lunch, or for a casual dinner. I purchased 3 colors.

Best comfortable field pants around!!!

As a wildly ranger, pockets are a necessity…along with comfort (as I live in the pants I wear in on my ‘hitches’). These were immediately comfortable. Pockets with zippers are GREAT! Only downside is the fabric pills in high wear spots, especially where my 75L pack rests on my hips. I foresee needing a new pair every 2 seasons but for prodeal price it’s an okay trade off since the comfort is 12/10. The waist tie is also excellent..I have no need for a belt now (but have the option for one…esp. if first aid is a priority [tourniquet]). Overall, the best pants I have worn in my 7 seasons but slightly saddened by the piling. Will buy again as there is a trade-off for comfy but not longevity

Great for summer, bad for longevity

I love these pants for summer hiking. They are lightweight, incredibly stretchy, and quick drying. I wear them almost every weekend when I go hiking. However they pill and fuzz insanely bad. I have so much pilling in random spots across these pants - some spots I don’t even know how they pilled?! It’s very disappointing as these pants are so highly rated but don’t perform as well as they are advertised. I have another pair of hiking pants from a different brand and they have not pilled once. I won’t be purchasing a second pair of these.

great pants!! started pilling quickly

Familiarity:
I've used it several times
Size Bought:
14

I've had these pants for two months, and I absolutely love them. I initially bought them for hiking, but I've also been wearing them around the house because they're super comfy and stretchy. I love that the have a button closure *and* a drawstring waist. The fabric is quite thin, great for hiking in the summer when it's warm out. I'd give them 5 stars except the fabric by the right front pocket started pilling after the first wash. It's super weird -- I'm not sure why just that area is pilling. I'll still wear them for sure, but I'm a little concerned they won't last very long.
