I've only worn it about three times. The tag has my name on it, so please purchase it if you don't mind. Color: Dark Black The Hidamari Everest is an all-three-layer structure type that boasts the highest level of heat retention in the Hidamari series. Our most popular product. Recommended for autumn and winter (especially cold seasons and scenes). ● The Hidamari Everest recorded a "6," the highest index, for the first time on the "Warmth Index," which is the standard for warmth in the Hidamari series. ● The sleeves and body use a three-layer fabric with high heat retention, and the wrists and ankles are double-layered, making it the strongest structure to prevent body heat from escaping. ● We have developed dark-colored products, which many customers have requested. You can choose from off-white to darker colors. ● Raglan sleeves (sleeves with diagonal seams from the neckline to the underarm) make it easy to move your shoulders and arms. ● It prevents cold air from entering from the neck and fits snugly, further increasing warmth and heat retention. 【Features of the Sapium version】 ◎ Heat retention and antibacterial and deodorizing functions are at the same level as the conventional version. ◎ The blend of the outer fabric is different (changed to 70% acrylic, 30% wool). ◎ Different fibers with antibacterial and deodorizing effects are used (using Toyobo's Sapium®). ◎ The color is slightly darker than the conventional version. Material 【Outer】70% Acrylic, 30% Wool 【Middle thread】95% Nylon, 5% Polyurethane 【Back (Danron®)】100% Polyvinyl chloride ※ This is the Sapium version.
