Mammut, born as a rope manufacturer in Switzerland in 1862, has accumulated over 160 years of history. By continuously creating innovative outdoor apparel and gear, we have provided everyone with the "ultimate experience." With the brand slogan "Rise with the Mountain – Challenge is Life," we support individuals who grow through challenges by offering high-performance products and proposing new concepts.

The Spring/Summer 2026 season theme is "DO IT ANYWAY. – Live Your Own Way." This slogan celebrates the shared psychology and exhilaration of mountain lovers. This season, Mammut continues to support those who challenge various goals.

From Mammut, the "Fast & Light Collection" (hereinafter, Fast & Light Collection), which pursues "lightness" and "mobility," will be launched on April 2nd. As outdoor activities become more diverse, a universal value sought by everyone from beginners to advanced users is "how to move lightly while maintaining necessary protection." To meet this need, Mammut's first "Ultra Light Collection" has appeared as part of the "Fast & Light Collection" this season. True to Mammut's style, the "Ultra Light" collection is also committed to protection and durability for those who enjoy activities. Furthermore, the hard shell lineup has been significantly expanded. Mammut has brought together the technologies cultivated in the mountains, refining techniques such as lightweight design, durability, and waterproofing, evolving into a collection where you can "choose the optimal piece" according to the field and style.

In addition, Mammut will introduce many products embodying the "Fast & Light" philosophy, such as the "Aenergy Trail" series of shoes specialized for trail running, and the lightweight popular hiking boots "Ducan III High LTH GTX."
