Down Long Vest

Provides all-night heat retention from shoulder to lower back

Used not only in winter but all year round

Cold is the cause of all illnesses. With a long back design, it warms not only the shoulders and back but also the waist. Since elastic material is used on both sides, it is easy to turn over. It does not interfere with your body movements and is comfortable to wear directly as a underwear. With down and plenty of heat retention, it takes less time to feel warm and supports a comfortable sleep. Ideal for relaxing time before going to bed as well as at bedtime. You can easily wash it at home.

Hypoallergenic and chemical-free

Using a process developed in the IWATA lab, Iozone (Ion + Ozone) ensures that allergy causing spores, dust mites, etc. are eliminated, for a completely safe, hypoallergenic down vest.

Uses selected down that has cleared strict quality standards

The feel of down products depends on the maturity of the down, not the down rate. The maturity of down is determined by the size of each down ball. Mature down has a large number of hairs, which makes it a large down ball and has high heat retention. On the other hand, immature down has low heat retention and is not comfortable to sleep on. IWATA uses only down that has cleared strict quality standards.

Ionization technology that enhances cleanliness allows washing with water

Conventional feather products could not be washed with water due to the risk of mold and odor. IWATA solves that problem with its unique ionization special technology. It can be easily washed with water at home and sterilized by sun-drying,
