From the manufacturer

The perfect layer for high output activities, from alpine approaches, backcountry tours or mountain runs that require added protection,

the Coefficient LT Hybrid Hoody is a stretchier, lighter version of our popular Coefficient fleece with added insulation. The Primaloft insulated, breathable, woven front panel provides warmth against the elements while the Polartec® Power Grid® fleece with a gridded interior increases wicking performance and adds breathability. A zippered chest pocket stores your phone or other essentials, while maintaining a minimal profile that is slim cut for ease of layering.
