The UF PRO® air/pac® insert is an intelligent 3-D spacer that provides an app. 8mm thick breathable air cushion, wherever it is inserted. It effectively blocks the heat transfer. The insert is light, flexible and almost not perceived by the wearer. When wearing a backpack or body armour, UF PRO® air/pac® inserts provide the extra benefit, of distributing weight and allowing air to circulate in areas of the straps of the backpack.
Why did we develop the UF PRO® air/pac® inserts?
A thermal, or cold bridge, is a heat transfer from warm to cold environments wherever the insulation layer is penetrated. In garment system this happens especially in areas between the hard or soft shell jacket and the body surface where an insufficient layer of air is encapsulated. Especially in the shoulder area this leads to an uncomfortable cold and damp impression, when being exposed to rain or just cold weather conditions over a longer period of time.
In order to overcome heat loss in these areas and to increase the comfort range of our garment systems our newest hard-shell and soft-shell jackets are equipped with UF PRO® air/pac® inserts, which can be inserted in these critical sections of the outer shell garment.
