Designed for fast ascents, the Aenergy SO features a smart hybrid construction. It combines a medium-weight double-weave Soft Shell with a lightweight Stormfleece fleece with a honeycomb structure. This combination of materials provides effective wind protection while maintaining a high level of breathability, even when the pace picks up. Moisture management is particularly well thought out to maintain a lasting feeling of comfort during prolonged exertion.
