A lightweight, packable, quiet, insulated vest designed to be utilized as both an outerwear piece and a layering option once temperatures drop. Whether you need to cut the chill for the archery opener or a Primaloft® Gold insulator to wear under your warmest parka in the snow, the Source Vest is a packable option for the whitetail hunter who needs warmth without the weight. The Source Vest is warmer and more packable than our Catalyst Vest. With a stretch fit for increased layering functionality, you don't have to worry about taking the vest off to climb into a stand or take aim with your bow. The Source Vest also features a collar that is high enough to be functional and warm, but not so high that it interferes when layering under other First Lite Whitetail pieces.
