The Albula is among Mammuts most sustainable insulated jackets. It is made almost entirely of recycled materials: the outer fabric is made of recycled polyester, lining is made of recycled polyamide. The Thermore Ecodown synthetic fiber filling is made from recycled PET bottles, making it the vegan,wash-and-wear alternative to down. It boasts excellent fill power as well as a high thermal rating even in damp conditions. The Albula is both comfortable and versatile. Its excellent warmth-to-weight ratio makes it great for hiking or everyday wear. On cold days, the loose cut makes it easy to combine with other garments and wear over a thick mid-layer.
