2) Internal structure
The warmth retention ability of a down jacket depends on the down quilting structure and quality.
*Quilting construction: The construction and technique of sewing fabric to wrap the down to increase warmth. The quilted construction evenly distributes the insulation and holds it in place, helping to retain heat and improve insulation.
AURORA DOWN JACKET IBUKI uses the same down as the classic AURORA DOWN JACKET, but in order to make full use of the warmth of down, the sides (underarms) are three-dimensional. In addition, by changing the inner seam (sewing) and outer seam (sewing), it has a body-fitting structure. In this way, the gaps in the clothes can be reduced, allowing body temperature to be transferred to the down, and giving full play to the thermal insulation properties of the down.
3) Down quality
AURORA IBUKI uses DX 90-10% Spanish duck down (760FP).
*"FP" is the abbreviation of "FILL POWER", a measurement standard for down, which stands for "the strength of down" or "the repelling force against its pressure". 760FP means that when tested under normal pressure, 30 grams of down rebounds 760 inches. The higher the FP index, the warmer the down is.
DX: Spanish Duck Down 90-10% (760FP) has high expansion capacity to capture more air and provide better warmth. This is an important factor in maintaining body temperature and feeling warm in cold environments.
When it comes to warmth, quilted construction is particularly important. A major feature of "IBUKI" is its three-dimensional structure, which firmly locks body temperature. Clever stitching inside and out ensures a snug fit and maximum warmth. "IBUKI" is a perfectly balanced down jacket that combines the power of Ibuki Mountain with Nanga quality.
