The Hollow men's street jacket is the brand's ultra-light jacket with Dupont Sustans Sorona® filling. It is a new type of environmentally friendly filler consisting of polyester fibers and renewable biological fibers. Thanks to its special fiber structure (3D spirals), the jacket has the following advantages: it is very light, dries quickly and most importantly, the air gets trapped between the spiral-shaped fibers, so it is able to keep warmer inside than a simple polyester-filled jacket. The filler is odorless, flexible and soft to the touch. Its sporty fit ensures maximum freedom of movement. Zippered outer pockets comfortably fit your valuables. The fixed hood and elastic edges kéép cold outside.
