Keeps body heat where it matters – thanks to reflective insulation
An aluminized layer backed with PET film creates a radiant barrier that reflects body heat back toward the occupant rather than letting it escape. The material also resists water ingress, helping maintain thermal performance in rain or snow.
Trapped warmth reduces the risk of hypothermia during short-term exposure and helps conserve energy while waiting for help. Suitable as an immediate first-aid shelter after a fall or unexpected overnight stop.
Ultra-light and packable – with a 110g aluminized film construction
Lightweight PET-film construction keeps mass to about 110g while allowing the bag to fold down to a compact size. Low bulk makes the item easy to store in a glove compartment or alongside other emergency kit.
Adds minimal weight to a rucksack while preserving valuable space, making it realistic to carry on day hikes or keep in a vehicle without inconvenience.
High visibility for rescue – with a bright orange exterior
A contrasting orange outer surface is chosen to stand out against natural backgrounds, increasing visual detectability for rescue teams. The same outer layer is durable enough for repeated use and simple cleaning.
Improves chances of being spotted from a distance or from the air and doubles as a signalling surface or picnic/makeshift shelter when needed.
