[PREMIUM COLLECTION] 087_P Double Tube Stand Collar Down

[ K-3B "THE PROFESSIONAL SPEC" PREMIUM DOWN]
A stand-up collar down jacket from the Premium Collection with a double tube construction for professional specifications.


The front end (inside the front zipper) has a double down tube built in. The front end is designed like a sleeping bag, but when you close the zipper, the down tubes are pressed tightly together from both sides to close the gap and eliminate cold spots around the zipper. A cold spot in down is a point where cold outside air gets in through the seams (needle holes) and causes the warm air inside to escape.

In addition, regular down jackets have quilting between each layer of down, and the pinholes in these seams can become cold spots, but the K-3B's down has down tubes placed on the back side of the seams as well, and the pinholes are blocked by the down on the back side, making it less likely for outside air to pass through and less likely for heat inside to escape.
Because this double layer down tube is placed all around, it uses about twice the amount of feathers as a regular down jacket .
This is the ultimate down jacket, providing ultimate cold and wind protection with absolutely no cold spots.


The zipper on the waist pocket is a functional zipper that can be opened and closed from both the top and bottom. For example, in rainy weather, you can open and close the zipper from the bottom to prevent rain and wind from entering, and in normal use, you can open and close it from the top to quickly take things in and out, allowing for flexible response. It comes with a strap with a stylish joint, which makes it easy to open and close. In addition, when force is applied to the strap, the joint part comes off to ensure safety.


Another feature of the pattern is that if both layers of the down tubes were stitched horizontally, the body would bulge horizontally, creating a rounded silhouette that would not fit the sides of the body. However, with this down jacket, the down tubes on the underside of the body are stitched vertically, creating a three-dimensional silhouette that fits the body.
This is an original manufacturing method used by craftsmen with extensive knowledge of down jacket design , and is not found in ordinary down jackets.

Furthermore, the sleeves have an ingenious sleeve attachment structure with gussets cut out under the sleeves, allowing for a very wide range of arm movement .
With ordinary down jackets, there is a tendency for the jacket to feel a little stressed when raising your arms and for the entire body to ride up, but with this Premium Down jacket we have done our best to eliminate such issues.

This premium down jacket features a stand-up collar design that creates a stylish look, while also providing functionality that makes it ideal for outdoor activities.
The matte texture does not shine too brightly, making it easy to match with mature styles, and we recommend pairing it with slim-fitting pants.
