Ecoalf Kalimalf Jacket - Men's Black M. The secret of the warmth of our jackets is in the thousands of feathers that we use. We have paired each jacket with a different Ecoalf fabric based on the animal we assimilated it from. This allows our jackets to be breathable odor free and lighter while also being resistant to water and wind. We use a goose down insulation in our jackets as it stows away the best when wet. This jacket is ultra compressible so it can be used when you're carrying a heavier pack. Our jackets use responsibly-sourced down free from conflict zones and unethical treatment. To make our jackets more ecological we use a SONIC regenerated nylon that significantly reduces the use of water and energy.
