Mammut Sender IN W

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 the world's only loop insulation, made from recycled rope production waste. And because the wind- and water-repellent outer material of a Sender IN Jacket is also recycled, it represents a huge step towards a closed cycle and therefore environmentally friendly production with the smallest possible impact on the environment.
