Thin, lightweight, yet warmThis vest uses the U.S. military's LAYERING SYSTEM "Level 5 Soft Shell", which is a system of clothing for extremely cold regions.
In addition to the highly functional shell, the inner shell is made of Thinsulate, which provides excellent heat retention.
SUNNY SPORTSAn American casual brand launched by surfer Shinya Kitahara. The brand offers basic, relaxed, high-quality daily wear with many items with a surf taste.
Multi-use as innerwear or outerwearSince it is thin, it can be worn as an inner vest for jackets and coats without being bulky and smart. Of course, wearing it as outerwear over a shirt or sweater is also a good idea.
The versatile, simple design makes this a multi-use vest that will be useful from fall to spring for a long season.
No Compromise on ConvenienceThere are large pockets on both sides for your convenience. The inside of the pockets are made of mesh fabric for excellent ventilation.
Functional materialThe use of "cation-processed yarn" on the outer fabric gives it a durable water repellent finish, making it lightweight and soft to the touch.
The back side is laminated with a polyurethane film to create a functional fabric that combines high durability water pressure, wind resistance, and moisture retention properties.
High heat retention by converting sunlight into heatToray's "Solar Sensor Fabric" used for the lining has carbon particles kneaded into the fiber to convert sunlight into heat and maintain high heat retention. At the same time, antistatic threads are knitted into the yarn to suppress unwanted clinging and static electricity.
Ideal Insulation Material Developed by 3MThinsulate, 3M's high-performance insulating material, is used for the padding. Thinsulate, developed by 3M in the U.S., is a new and ideal insulation material that is completely different from conventional polyester cotton and down.
Air is sealed in between the intricately intertwined microfibers with a diameter of 2 microns. It is approximately 30% lighter than regular cotton padding and takes into account outside temperatures and other factors to provide comfortable warmth.
