Made from 100% recycled materials, the Mammut Sender IN Hooded Jacket keeps us warm in sub-zero temperatures while taking a big step toward a circular economy. The recycled ripstop shell is both wind- and water-resistant, and we really like the idea of the new LOOPINSULATION, which is made from recycled rope scraps. That's a great way for Mammut to leverage its strength in ropes to make a technical outdoor insulator with less of an impact on the environment.
