A jacket nicknamed the "Marshmallow Suit" in America, named Urban Gray. This model was issued and used by the US Army and other branches. It has been priced at 132,000 yen at a certain used clothing store, and it is believed to be worth even more now. The WILD THINGS model with Urban Gray and EPIC (EPIC) for the outer shell only exists in test samples and early models. A square Velcro patch for attaching rank insignia and name labels is applied to the chest area, but in the extremely rare test samples, the rank insignia (■) usually found on the right chest is placed on the left chest. The filling uses PrimaLoft, an innovative ultra-fine microfiber material developed by Albany International at the request of the US military to replace down feathers. Due to these materials, it can be washed in a home washing machine without the need for a dry cleaner, which is essential for heavy clothing. Features of the test sample: ・The shell color is darker than later models. ・The chest Velcro patch (■ shape) is on the left chest. ・A hanger loop is equipped at the neck. ・The size feels slightly smaller than later models.
