This Frizmworks deck jacket is made of solid thick broken twill fabric. In the case of the neckline part and the upper part of the lining, a rich two-tone microfur was installed to give a soft fit. For the lining, 6oz of filling material was quilted in the shape of a jar, and heavy microfur was placed together to provide a very high level of warmth. The quality of the zippers used was improved by using YKK's products, and for the main button, a military-type button was selected, and the bottom button was installed inside to prevent easy loosening as much as possible. The lower pocket entrance is made of the same material as piping to increase durability.
