This is an ideal heavyweight mid layer thermal underwear mid layer where extra neck protection is required but also giving you the option of venting yourself if you should overheat. Suitable for all cold weather and winter activities including mountaineering, polar expeditions, skiing and canoeing, or under your motorbike leathers. Don't get stuck out in the cold without the right thermal protection. A cold motorcyclist is 5 times as likely to have an accident then one that is comfortable in their riding gear.
