Mobility is the name of the game with the Ferrosi Joggers from Outdoor Research, They feature the famous Ferrosi fabric, a nylon-stretch blend that's dialed in for climbing, hiking, running, and training, thanks to its wind and water resistance, breathability, and movement-mirroring stretch. The jogger-style Ferrosi features a tapered calf with internal elastic at the ankles to see our feet when we're climbing or scrambling, a harness-compatible waist, and a semi-tailored, articulated cut that maximizes our freedom of movement when we're living our active lifestyle.
