BRAND DANESE This warm teddy jacket ensures a high level of warmth and breathability, and it is certainly going to keep you warm in the colder months. The teddy fabric is crafted from recycled polyester and is knitted to simulate animal fur with the fibers vertically oriented. This provides a large volume of air trapped in the fabric, and hence a high insulation-to-weight ratio. knitted to simulate animal fur with the fibers vertically oriented and this provides a large volume of air trapped in the fabric, and hence a high insulation-to-weight ratio.
