MAMMUT belay jacket with hood, size M. Originally designed as a belay jacket to keep warm on the wall during climbing, it's also ideal for general outdoor use due to its durability, light weight, breathability, and water repellency (made of PERTEX Quantum). Unlike GORE-TEX, it's lightweight and thin. Excellent insulation and functionality. Purchased 5 years ago at Kanda Sakaiya Sports, used 5-6 times. I wore it for warmth during mountain hut stays and tent camping. - Brand: MAMMUT - Size: M - Color: Blue/Navy - Features: Hooded, zippered pockets Thank you for viewing.
