The Exciting Collaboration of MERRELL and GRAMICCI: Introducing the MOAB 2 SIREN X GRAMICCI
On October 24, 2025, outdoor enthusiasts will be treated to a remarkable new release from the iconic American outdoor brand, MERRELL. In a unique first collaboration with the innovative apparel brand GRAMICCI, they're set to launch the MOAB 2 SIREN X GRAMICCI — a reimagined version of their symbolic footwear known as MOAB.
This collaboration embraces a blend of movement, tradition, and modern adventure spirit. MERRELL, a global leader in outdoor footwear, has taken its classic MOAB design and integrated bold style with performance features in this special edition model. The MOAB 2 SIREN X GRAMICCI will be available in two captivating colors: DARK CITRON and DARK EARTH, showcasing an upper design based on the reinterpreted “SIREN WEB” collection. This new model provides not only comfort but gripping traction, built upon the highly trusted midsole and outsole of the original MOAB 2, making it a versatile choice suitable for trails, rocky terrains, and city excursions alike.
Both MERRELL (founded in 1981) and GRAMICCI (established in 1982) share a close-knit history within the outdoor industry, having significantly influenced it in their own rights, just a year apart. GRAMICCI draws roots from the climbing counterculture of Yosemite, known for their innovative items like shorts with a gusseted crotch and webbing belts tailored for freedom of movement. On the other hand, MERRELL continues to advocate for outdoor exploration with its well-known slogan, “LET’S GET OUTSIDE.” The MOAB series stands as a symbol for explorers worldwide, widely recognized as one of the best-selling hiking boots globally.
This partnership between these two trailblazing brands honors their distinct legacies while striving for a redefinition of contemporary outdoor culture.
