Size: M Color: GRAPHITE GRAY Excellent condition. *Please read the profile first. A thin insulation jacket that excels as a mid-layer in the outdoor field. Both the outer and inner fabrics use Pertex Quantum Air, which is lightweight, supple, and has excellent breathability. The breathability allows for both moderate heat retention and reduced stuffiness during activity. PrimaLoft, which is lightweight, has excellent heat retention, and maintains loft even when wet, is used as insulation. This thin-fill type comes with a stuff sack for compact storage, making it very portable. We also paid attention to the minimalist appearance, making it as stitch-free as possible. The hem and cuffs are finished with thin binding, making them less noticeable. This is a single piece that pursues the functionality required in the outdoors within a simple design that eliminates waste. This is a "GREEN MATERIAL" product that uses recycled materials (insulation) with consideration for the environment.
