Technology
NeoDown®
The NeoDown® insulation combines hollow recycled polyester fibers with 24% Sorona® BIO, creating a lightweight three-dimensional structure that traps warm air and maintains body temperature consistently. Its thermal performance remains stable even in humid conditions, without losing loft or compressibility.
The 20D nylon outer fabric (42 g/m²), treated with PFC-free DWR C0, repels water and improves durability under intensive use. The result is a comfortable, soft, and lightweight warmth that defines the FAST&LIGHT concept.
