All about this product



Over or under. The insulating Arctic Jacket from Mammut is the perfect cozy fleece to wear under a hard shell or as a breathable outer layer. The integrated Polartec Thermal Pro material has large pores to store air that has been warmed by the body, meaning excellent heat retention for long hikes in blustery winds. The material also dries extremely quickly after demanding ascents, with an ideal heat/weight ratio, flatlock seams for extra elasticity and pre-shaped elbows for unrestricted movement. With all this and more, the Arctic Jacket is the ideal fleece for sporty winter pursuits.
