LUMITHERM is KILPI's own heat-reflective lining technology that helps keep your body heat where you need it – close to your body. It uses the principle of infrared radiation reflection and brings more thermal comfort without an extra bulky layer.
Your body naturally produces heat, but some of it radiates into the surroundings. The silver heat-reflective LUMITHERM print helps reflect part of this radiation back to your body, reducing heat loss. Combined with the insulating properties of Kilpi's own EMPORIUM filling, you get more warmth with minimal extra bulk.


Room to breathe
Thermal comfort is not just about retaining heat. Moisture management during movement is just as important. That is why the silver LUMITHERM lining does not form a continuous surface: the gaps between the reflective parts leave room for vapour to escape. Protection from the cold goes hand in hand with comfort during activity.
Technology for winter activity
We developed LUMITHERM for the moments when you want to be outdoors even in cold weather. It uses the heat of your own body and adds a light heat-reflective layer to your functional gear. On the slopes, on a winter walk or during a break between runs, it helps maintain thermal comfort so you can enjoy winter to the fullest.
