The PrimaLoft Vest is Norrona's lightest and most packable insulated vest for all season use. This windproof insulated jacket can be worn alone to keep your core warm, or in combination with a shell jacket to give added protection to your arms. The PrimaLoft maintains excellent insulating powers even when wet, and has a higher warmth-to-weight ratio than fleece.
And for an increased and snug fit Power Stretch side panels have been added. The vest can easily be compressed into a Packable Pocket making it a natural addition to your pack. Additional functional features include above harness hand warming pockets, a warm and weather protective collar and a one handed elastic adjustment in the hem.
