The Echo, Frontier, Mission and Vulcan Jackets are all softshell jackets with three pockets, but they’re quite different products. The Echo is a lightweight softshell perfect for aerobic activity or warmer environments, but its thin fabric provides little warmth. The Frontier jacket uses the same fabric as our bestselling Ibex and Chamois pants and provides a middle-ground of durability, weather resistance, and a useful amount of insulation. The Mission Jacket is thicker, heavier and warmer again, so better suited to colder conditions. It has pit zips which enable you to vent the jacket when you get too hot. The Vulcan is the warmest and most weatherproof of all of our softshell jackets. Despite its pit zips, in mild conditions it might be overkill, but for cold and windy weather it is perfect, and its durability means it should last many years.
