YOUR PURCHASE IN ACTION

Our GiveBack100 Promise

Less than 2% of all charitable contributions globally go towards our most significant threats: climate change & biodiversity loss. That’s why we have pledged to donate 100% of our net profits to organizations that directly combat our biggest environmental challenges, including coral reef protection, land & water conservation, and reforestation. And we let you decide which cause matters most to you.

Tellus is the first of its kind. But for everyone’s sake, we hope it’s not the last.

OUR MISSION IN ACTION

Sustainability First, Second & Always

We’re rethinking the way clothing is made to bring about a better planet, stronger communities & brighter future.

Our Materials

100% of Tellus products are made using some form of recycled material, and the vast majority of our products are made using nearly all recycled materials. Oftentimes, these materials are recycled versions of things like polyester, but we’re also incorporating more innovative materials like Seawool, which we use to create our joggers and performance shorts and is created from plastic bottles and oyster shell waste.

Our Suppliers

During their time in the Peace Corps, founders Joe & Melissa saw how big industry had the potential to devastate or uplift a community and vowed that Tellus would do the latter. Every supplier in the US and in Vietnam has been vetted through research or in-person visits to ensure they share our standard of excellence and, more importantly, our ethics around the fair treatment of workers.

Our Community Partner

Choose Which Cause Matters Most To You

We are proud to partner with The Nature Conservancy (TNC), supporting its mission to conserve the lands and waters on which all life depends. TNC's exceptional work in land and forest restoration, ocean conservation, and wildlife protection — along with its strong presence in Colorado and worldwide — makes them our ideal first partner.

Coral Reefs

Land & Water

Reforestation

Coral Reef Protection

WHY THIS CAUSE MATTERS:

A healthy reef is an incredibly complex ecosystem that helps protect delicate shorelines from damage and erosion. Over 1 billion people around the world rely on coral reefs for food, livelihoods and the land where they live. Yet, coral reefs are rapidly succumbing to ocean heatwaves caused by climate change. As ocean temperatures continue to rise, reef bleaching is decimating this vital living organism.

OUR PARTNER IN ACTION:

Fortunately, there is hope as researchers have discovered super reefs that are proving resilient to warmer waters. These super reefs are sharing their secrets for survival and helping scientists conserve and protect the world’s coral reefs. The Nature Conservancy, along with partners, is participating in a collaborative effort to help coral reefs persist in a warming world.

Land & Water Conservation

WHY THIS CAUSE MATTERS:

The loss of biodiversity due to habitat destruction further exacerbates climate change, jeopardizing all life on Earth. Extinctions of plant and wildlife species are happening faster than ever. If we remove too many pieces the health of our environment, food supply and economies could crumble. But if we can agree to prioritize biodiversity, we can save the planet and ourselves.

OUR PARTNER IN ACTION:

Through the America the Beautiful campaign, The Nature Conservancy is driving a nationwide initiative to conserve 30% of America's lands and waters by 2030. We applaud this initiative's extensive reach across all 50 states. Developing and implementing strategies to protect, manage and restore critical ecosystems that not only reduce greenhouse gas emissions, but also promote biodiversity.

Reforestation

WHY THIS CAUSE MATTERS:

Climate change is making wildfires larger, more destructive, and more frequent. In fact, the 20 largest wildfires in our home state of Colorado have all occurred within the last 20 years, and the fire season now lasts 75 days longer than it did in the 1970s. Because of climate change, these forests are also less able to regenerate after a wildfire, leading to permanent loss in biodiversity and outdoor recreation opportunities.

OUR PARTNER IN ACTION:

The Nature Conservancy's Healthy Forests and Watersheds initiative is dedicated to restoring 500,000 acres of forests in Tellus’s home state of Colorado, including those unable to regenerate naturally. Along with transitioning away from fossil fuels, natural climate solutions offer immediate and cost-effective ways to tackle the climate crisis—while also supporting healthy, thriving communities and ecosystems. This initiative prioritizes forest restoration, particularly reforestation and safeguarding watersheds. Healthy watersheds ensure clean water for people and wildlife, and they support agriculture and food production, industry and outdoor recreational activities in the process.

Oyster Shells + Plastic Bottles = Seawool Yarn

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.
