The Mountain Equipment M LIGHTLINE VEST is an extremely warm and technically sophisticated down vest that provides optimal protection in freezing temperatures without restricting freedom of movement. Based on the popular Lightline Jacket, this vest offers maximum flexibility and keeps the upper body comfortably warm even in the harshest conditions. The high-quality 700 cuin down filling is processed in quilted chambers to prevent cold spots – especially in critical areas such as the shoulders and chest. With the certified DOWN CODEX, the focus is on quality and sustainable sourcing. The lightweight, windproof, and highly water-repellent DRILITE® Loft outer fabric with PFAS-free DWR treatment provides reliable protection from moisture, snow, and wind while remaining breathable. A robust YKK two-way zipper with insulated cover ensures optimal thermal insulation. Practical details such as an inner zippered pocket and hand-warming side pockets make the vest the perfect companion for demanding outdoor adventures. Reliable, functional, and warm—ideal for anyone who wants to stay active even in sub-zero temperatures.
