Garments made with 3DeFX+ insulation provide unprecedented elasticity that moves along with the body. With 3DeFX+, your insulation layer can stay on the whole day.
The innovative secret behind the Kooshin’s performance is 3DeFX+: a three-layer sandwich of breathable, stretchy shell and liner fabrics, surrounding three-dimensional stretch synthetic insulation. 3DeFX+ insulation is composed of four types of spiraling, hollow-core polyester fibers. This unique formulation provides lightweight, lofty insulation with incredible flexibility and stretchability. The shell and liner fabrics are completely breathable, stretch-woven nylons with a soft and supple hand. The 3-layer package provides unprecedented stretch and comfort for cold-weather aerobic activities.
