STONEMASTER / SM Swing Top Jacket/Lined Polartec Alpha

Jacket with a unique look
STONEMASTER has introduced a jacket with a unique look and feel.

The highly functional material “POLARTEC Alpha” is used to create a thin fabric with amazing heat retention properties. The world’s first pigment dyeing process has been applied to this highly functional material to create a highly expressive garment without the luster characteristic of synthetic fibers and without the feeling of gear.

STONEMASTER
The brand of legendary climber Mike Graham, founder of Gramicci and other brands. STONEMASTER combines the technology and know-how of the outdoors with the stylishness of everyday wear to offer truly modern, everyday clothing.

World’s first technology-filled fabric
The outer fabric is made of windproof polyester with a pigmented finish for a matte, expressive look.

The lining is made of POLARTEC Alpha, a lightweight, breathable, heat-retaining, and quick-drying cotton material developed for the U.S. Special Forces. It also helps to release excess heat and perspiration inside the garment, keeping the wearer comfortable at all times.

Also, while there have been products with pigmented fleece, STONEMASTER was the first in the world to successfully process the fleece for the “POLARTEC Alpha”. The temperature control of the processing is more difficult than with fleece, and the brand’s high level of technology can be seen in this piece of clothing.

Vintage-inspired details
Snap buttons are used on the front placket. The easy-open/close snap buttons enhance convenience and at the same time function as a design accent.

Pockets on both sides are zipped. It also has a packable function as well as a pocket function. It can be compactly stored in the pocket on the right side, which is convenient when traveling or keeping it in a bag.

Pigment dyeing throughout gives the jacket a unique character, and the unevenness of the seams gives it a vintage look. These particular details give the jacket a classic impression while shaping a contemporary style.

Sophisticated, lightweight appearance
The refined silhouette of the lightweight and toned fabric allows the design to naturally follow the lines of the body without the bulkiness of typical fleece. It supports active movement and provides a smart impression that blends in with urban living.
