The Mountain Equipment W Aerotherm Vest is the ideal softshell vest for fast-paced mountain activities. Its lightweight, double-woven Exolite 45 softshell fabric with PFC-free DWR finish provides reliable protection from wind and moisture, while the moisture-wicking Micro-Grid lining ensures a comfortable climate. The lightweight fleece insulation keeps your upper body warm even in windy conditions without weighing you down. Thanks to the semi-elastic waistband and armholes, the vest fits comfortably and does not restrict your freedom of movement. The closable pockets are practical for safely storing small items. And when you don't need it, it can be packed away small or attached to your climbing harness – so you're perfectly equipped for changeable weather conditions.
