Outdoor Research Ferrosi Hiking Pants Review

Fording Stream in Ferrosi Pants

Outdoor Research Ferrosi Hiking Pants are full-length soft-shell hiking pants with a lot more stretch (14% spandex) than most hiking pants. I like to wear them in warm to hot weather on and off the trail because they are comfortable and look so good. They are hipbelt and climbing harness-compatible with five pockets, including two that zipper close. Elastic drawcords at the ankle let you roll them up if you want to vent your lower legs while the 90D Ferrosi ripstop fabric is remarkably durable and breathable.

The Ferrosi Pants have a zippered thigh pocket in front

The Ferrosi fabric that these full-length pants are made from has a cult following in the outdoor community because it’s so lightweight and stretchy, but amazingly durable at the same time. They also feel fantastic whether you’re wearing them for hiking, climbing, traveling, or on a hot date! Seriously, they are nice enough that you can wear them for semi-formal occasions (they do have a stenciled logo on the left thigh) but they look a hell of a lot better than your normal cargo hiking pants!

Functionally, the Ferrosi pants have five pockets, two drop hand pockets up front, two in the rear, and one on the right thigh – the thigh pocket and right rear pocket both close with zips. The pants have a button front closure, zipper, belt loops, and an internal drawstring which is useful when they’re worn with a climbing harness or a backpacking hipbelt. You just need to be very careful not to let that drawstring get pulled into the pants, particularly when washing them because you’ll never get it out again.

No belt, no problem. There is a hipbelt and harness compatible drawstring inside to hold up the pants which is much more comfortable than wearing a belt.

In addition, the cuffs of the legs have drawstrings so you can pull the pants up over your knees, tighten the drawstring, and wear them like shorts for stream crossings. Although they are so fast-drying, you often don’t have to bother. These Ferrosi pants are also available as zip-off convertible hikers if you prefer that leg styling: they are otherwise identical to this full-length leg version.

Recommendation

I think these Ferrosi full-length hiking pants make good late spring and summer pants because they are so breathable and fast-drying, particularly when you need the extra sun or brush protection of full-length hiking pants. Highly Recommended!

  1. Ive had pairs of these for over 10 years I think, and I agree with the review. These pants are awesome!

  2. Thanks for the review! I’ve been getting non-stop emails from Outdoor Research hawking these pants but have never seen a pair “in the wild”. I’ll try a pair.

    Bought a pair last year and the stitching started to fail on the seams after a few short trips. Luckily I own a sewing machine and was able to shore everything up. Ended up buying 2 more pairs anyway because I absolutely love everything else about the Ferrosi. Maybe the newer ones will be okay and it was just a one time factory glitch, but regardless I’ll repair the new ones if need be. The pants are otherwise super tough, very comfortable and resist wrinkling. They’re pretty smart looking really.

  4. I have a pair and they are super comfortable, however I find them a bit snug in the crotch in the thigh …. I even though I’m I may have bought the women’s by mistake. I’m not that idly shaped

  5. I’ll stick with KUIU Tiburon pants. Airy and has zippers on side for ventilation.
