Outdoor Research’s Ferrosi Convertible Hiking Pants are highly breathable and quick drying convertible hiking pants with zip-off legs. They’re very stretchy which makes them great for scrambling and even rock climbing, with a gusseted crotch that provides great range of motion. In addition to zip-off legs, there’s an elastic band in the ankle cuffs which lets you pull the legs up to calf or even knee-height to keep them dry for stream crossings or just to cool off. I also like the fact that they have a UPF+ rating which means they block 98% of the sun ultraviolet light from reaching your skin. If you spend a lot of time outdoors or live in a bright sunny climate, it pays to be careful with your sun exposure over the long haul.

The distinguishing characteristic of OR’s Ferrosi Convertible Pants is their stretch. But they’re not hiking tights, they’re pants, with pockets and all the features that day hikers and backpackers want from a pair of hiking pants.
The pants have a regular cut and the fabric is very soft and comfortable. They’re also very lightweight and almost feel like you’re wearing silk, instead of ripstop nylon. Their breathability is also off the charts. I sweat copiously when I hike, regardless of the temperature, and these pants keep my waist and calves dry and perspiration free which I find kind of astonishing.
If you’re still too warm or you feel like a dip at the local swimming hole, you can zip off the pant legs. The zip-off leg zippers are color-coded, a light grey and a dark grey, so you can match them up to the right legs when you put them back on. Alternatively, there are elastic bands sewn into the cuffs, that let you pull the pants up over your calves or even up above your knees for more ventilation, kind of like the roll-ups provided on other hiking pants. These are really handy for stream crossings when you don’t want to bother unzipping the legs to keep your pants dry, but just want to roll the legs up for just a few minutes.
The Ferrosi Convertible pants have five pockets, two in front, two in the rear, and one zippered pocket on the right thigh which is sized for a smartphone or wallet, when traveling. The two front pockets are made with mesh for breathability, but like the rear pockets, they’re open on top without zippers or button-down flaps for added security.
The pants don’t come with a belt, but have 2 and 1/2 inch belt loops sewn in. The tricot-lined waistband is soft for increased comfort and closes with a button and zipper fly. I use a soft webbing style belt and find these pants to be quite comfortable when worn under a backpack hip belt.
