The Gatherer jacket by Merrell is not high-tech but the concept of using materials that are available at any time as insulation goes along with my idea of modularity and sustainability.
The product description by Merrell: We all know how quickly the weather can change from comfortable, to cold and back. Our Gatherer jacket lets the wearer adjust their own climate to the conditions using adaptive insulation pockets through the body and sleeve. These pockets can be filled with insolating material of any kind; from newspaper and leaves to packing peanuts or stuffing from an old pillow. The only limit to your ability to stay warm is your imagination.
