The Rescue series is optimized to withstand extreme conditions in alpine environments. Many of the garments in the Rescue series have extra reinforcements and all Rescue garments have an integrated Recco reflector. It is used to make it easier for mountain rescuers to find you if you come across an avalanche, injure yourself in the forest or get lost in the mountains. The rescue personnel use a RECCO detector to be able to quickly scan search areas. When the radar signal from the detector hits a reflector, the signal bounces back and indicates where the missing person is. Read more about the products here.
