The one piece of outdoor clothing you won't want to do without. The Mens Winter Travel Henley Long Sleeve Top from Jack Wolfskin is made of a slightly thicker baselayer fabric that feels great next to the skin and is extremely warm. And because it is cut a little longer, it also keeps your kidneys and waist warm during more dynamic activities. Wear it for leisure, travel or business–It is so breathable and fast-drying you'll feel great in it all day long. And it's smart enough that it doesn't look out of place in the office. The fabric is also odour-resistant.
