The Mountain Equipment M FRACTAL JACKET is a versatile hybrid insulation jacket, ideal for a wide range of mountain tours. The lightweight, windproof 20D outer fabric with PFAS-free DWR provides reliable protection against moisture, while the POLARLOFT® insulation on the body and arms ensures comfortable warmth with low weight. Stretch fleece inserts with a brushed interior offer additional comfort and freedom of movement. The slim Alpine Fit and quilted construction guarantee a perfect fit. Practical details such as the YKK® front zipper, two zippered side pockets, a partially elastic hem, fleece cuffs with thumb loops, and an internal zippered pocket make the jacket functional and comfortable for use as a lightweight outer layer or warm midlayer.
