Streamlined ThermoBall™ baffles are contoured to fit your body and maintain core warmth during winter excursions in cold, wet weather. Wear this thermal vest as a mid-layer for added warmth in the coldest winter days or pack it for emergency layering in the backcountry. 15D 33 g/m2 100% nylon with non-PFC durable water-repellent (DWR) finish. 11.5 g/ft2 ThermoBall™ synthetic insulation made with 100% recycled polyester polyfill. Durable water-repellent is applied to the face of the fabric to provide the first line of defense against wet weather. Plus, insulation traps hot air for reduced heat loss and increased warmth. Highly compressible layer for emergency use or travel. Designed to replicate the qualities of down, but retain them even when wet.
