This is 'MERELY REVERSIBLE PADDED SHIRTS', which returned in its 4th version after its first appearance in the 19FW season.
This season, the Japanese 'SUNWELL' wool flannel fabric has a luxurious texture and 'MASUDA' is soft touch and 'dust-proof', which prevents static electricity. The functional nylon fabric is adopted to maximize comfort and stability. It is a reversible top with 2 different vibes in one piece, offering an array of different potential styling that you can layer or wear on its own.
There are a total of 4 storage pockets including left/right side slit pockets, a chest pocket on the top left, and a kangaroo pocket on the back bottom.
