The Jack Wolfskin Icy Tundra Padded Jacket is lightweight, warmly insulated and windproof with hood. It has three key attributes: it is warm, lightweight and robust. Three features that are particularly useful when you are engaged in strenuous activities in wintry conditions. It features our robust Microguard Maxloft synthetic insulation. This new version transports moisture away from the body even faster. And the windproof outer fabric delivers enhanced heat retention performance. The jacket can also be used as a liner for a weatherproof shell jacket as it is equipped with a Snap In system, which allows it to be docked with any Jack Wolfskin compatible outer jacket.
