The Outdoor Research Ferrosi is the lightest weight softshell jacket that we reviewed and is also one of the least expensive. While it does not compete with thicker jackets that offer more in the way of weather protection, its breathability and mobility performance made us reach for the Ferrosi when we were going to be seriously active. On mountain bike rides, trail runs and on rock climbs, the Ferrosi lets the wearer move unencumbered, and the thin softshell material lets perspiration quickly pass through.
Other jackets such as the Rab Torque performed nearly as well in these metrics, offering additional weather resistance thanks to the inclusion of a hoo. However, the price of these close competitors was at least double that of the Ferrosi. Pair the Ferrosi jacket with a lightweight base layer, and you have a capable wind shell that will shed very light moisture and let you focus on your activity.
