The Aequilibrium Softshell Jacket W by La Sportiva is a very light, technical softshell jacket made from a functional mix of materials: windproof GORE-TEX® INFINIUM™ on the shoulders, arms and hips, elastic and breathable material everywhere else and even more elastic fabric on the back and underarms for maximum freedom of movement. The fabric has a durable water-repellent finish and anti-odour equipment. The jacket itself has an adjustable hood that can be attached to the collar to prevent it from flapping in the wind, elasticated cuffs and two climbing harness and backpack-compatible side bags plus an elasticated chest pocket.
