Mammuts Aconcagua is a classic fleece jacket for sporty lifestyles. Now in its third generation, it still holds its own on expeditions, and long and short outdoor adventures and is also suitable for everyday wear. The Polartec Power Stretch Pro material is comfortable and ensures you can always move freely thanks to its flexible 4-way stretch material. The fleece fabric keeps you warm, efficiently wicks away moisture, and dries quickly. The Aconcagua has a tight fit, making it your go-to mid-layer for wearing under a hardshell layer. Its tried and tested features and timeless design also make the jacket perfect for wearing on its own when hiking, climbing or just enjoying your free time. The Aconcagua is made to offer superior quality, is extremely rugged, and always keeps its shape.
