So lightweight yet so warm, the full-zip Peninsula Insulator Jacket is built to ward off the cold and other surly elements. The Primaloft® Black Series Insulation offers ultimate softness, warmth and comfort, while pockets with RAPIDraw™ pass-through and a hidden chest pocket keep you confident and ready. The main body features our extra tough mini ripstop fabric with plain weave overlays and a DWR finish. But there's more. The Insulator folds into a removable stuff sack that fits in a hand pocket. Portability rules.
