Men's Stone Glacier Cirque Vest 18284-20012-MK The Cirque Vest fills an important niche in your system as a breathable insulator for use as weather-resistant outerwear or as insulation underneath a shell to provide warmth where you need it most without sacrificing breathability or mobility. Technology Pertex® Quantum uses a tightly woven structure to provide a light and soft fabric that allows insulation to fully loft while also being quiet, wind-resistant, lightweight and packable. For hunts requiring warmth, especially in cold and wet conditions, Primaloft® Gold insulation is a go-to for technical performance. Engineered for a full spectrum of benefits to provide warmth without bulk resulting in freedom of movement for your activity. One of the main differences between natural down insulation and Primaloft® is the ability to maintain warmth when wet.
