The Alberta Ferretti x Skyway collection is a project to help support efforts to safeguard the glaciers.

The brand has teamed with Skyway Monte Bianco, the cable car that links the city of Courmayeur, Italy, in the Aosta Valley region with the south side of the mountain, to develop a limited-edition capsule collection.

The capsule includes two sweaters crafted from recycled cashmere and featuring the statement “Save the Glacier.” Available in black or white versions, each knit retails for 495 euros at Alberta Ferretti boutiques and online store. In addition, the capsule hit the shelves of a selection of retailers and of the Skyway Monte Bianco shops.

A portion of the sales will be donated to support environmental projects aimed at safeguarding the glaciers.
