Mammut Transmitter In

This particularly lightweight insulating jacket keeps you nice and warm even in sub-zero temperatures thanks to its exceptional synthetic fibre filling. It consists of our globally unique loop insulation, made from recycled rope production waste. And because the windproof and water-repellent outer material of a Sender IN Jacket is also recycled, we have taken a huge step towards a closed cycle and therefore environmentally friendly production with the smallest possible impact on our environment.
