The Arctic IV ML Jacket is Mammut's cozy, high-collared fleece mid layer. It is made from Polartec Thermal Pro fleece, which is soft and fast drying yet durable and resistant to pilling, with a lofted structure that holds warmth. It weighs 463 g.
The trade-off of a lofted fleece is bulk. It is warmer and softer than a thin stretch fleece, but it packs larger and does not layer as slim under a fitted shell. For cold days and relaxed outings, that loft is the point.
It is for winter sports and relaxed days outdoors, from lift-served skiing to walks around town. Flat seams keep it comfortable under a backpack.
Regular fit with a high collar, two zippered side pockets, a zippered chest pocket and an elastic hem and cuffs.
We love the Arctic IV as a classic, warm fleece that feels just as good on the hill as it does at the end of the day.
