Since 2011, Green Events has been hosting sustainable, community-driven races that promote an active lifestyle while minimizing environmental impact. Founded by race director Lisa, the organization has grown from a weekend hobby into a mission-driven initiative. Tellus is proud to sponsor four major Fort Collins events this year: the Polar Bear Plunge & 5K, the Spring and Fall Equinox Races, and the Choice City Running Festival. These events celebrate fitness, community, and environmental stewardship—values that mirror our mission.

Through years of innovation and research, Creative Tech Textile Co., Ltd. developed a pioneering method to repurpose discarded oyster shells by blending them with recycled PET bottles. This breakthrough led to the creation of Seawool, a high-performance recycled fabric that brings sustainability to the textile industry. As part of our commitment to eco-friendly apparel, Tellus uses Seawool in three of our products: Men’s and Women’s Sunset Ridge Tech Shorts, Men’s Sunset Ridge Performance Joggers and the Men’s Old Town Button Down.
