Updated with streamlined ThermoBall™ powered by PrimaLoft® baffles contoured to fit your body and maintain core warmth during winter camping excursions in cold, wet weather. Wear this thermal vest as a mid-layer for added warmth on the coldest winter days, or pack it for emergency layering in the backcountry.
Insulated: Insulation traps hot air for reduced heat loss and increased warmth.
Packable/Stowable: Highly-compressible layer for emergency use or travel.
Synthetic: Designed to replicate the qualities of down, but retain them even when wet.
