Our Mission

Make sustainability cool and universal through our products and ventures



For each Rhino and Elephant cap sold, we will donate $5 to the World Animal Protection, a non-profit dedicated to protecting species –– especially those harmed by global warming or the severe and dangerous practices that propel its course. When we sell a Rhino Cap, our $5 might go towards feeding an endangered species for several weeks (perhaps an elephant) or could contribute to raising awareness about the cruelty of animal captivity or the harmful climate effects of mass farming. When we sell an Elephant Cap, the $5 we send to World Animal Protection could go towards feeding an endangered species for several weeks or contribute to raising awareness about the cruelty of animal captivity or the harmful climate effects of mass farming.


For each Dolphin hat sold, we will donate $5 to Dolphin Spirit, an initiative of Edge Innovations, dedicated to replacing dolphins in captivity with life-like robotic dolphins. Their goal is to put an end to the imprisonment of over 3000 dolphins currently held and being used for entertainment. When we sell a Dolphin Cap, the $5 we send to Edge Innovations will help advance their technology to create a new kind of educational and entertainment experience.


For each Coral hat sold, we will donate $5 directly to Lonely Whale, a global incubator founded on “radical collaboration” that takes courageous ideas and helps create impactful change to protect our planet’s oceans. When we sell a Coral cap, the $5 we send to Lonely Whale go towards educating future generations on the gravity of global warming.


For each Penguin hat sold, we will donate $5 directly to Make a Change World, an organization dedicated to ridding bodies of water of plastic and working towards sustainable solutions to our global plastic problem. The Arctic is a “dead-end” for ocean plastic, and a recent study by National Geographic found disproportionate amounts of micro-plastic in samples of Arctic ice, which in turn serves to destabilize the fragile ecosystems. When we sell a Penguin Cap, the $5 we send to Make A Change World go towards cleaning Indonesia's plastic-polluted waterways.

For each hat of the Renewable Line sold, we will donate $5 to Bondh E Shams, a global water charity that uses innovative renewable energy sources to provide clean water to millions of people. When we sell a Wind Turbine Cap and send $5 to Bondh E Shams, this translates to 2.5L of water saved per day for 20 years, which equals 10 cups of clean water every day while their project is active.


For each Tree hat sold, we will donate $5 to Eden Reforestation Projects, a 501c3 non-profit that plants millions of trees every year through fair wage employment. Local community members are hired to plant and guard to maturity native forest species on a massive scale. Their “Employ to Plant” methodology results in a multiplication of positive socio-economic and environmental issues. When we sell a Tree Cap, the $5 we send to Eden Reforestation Projects directly translates to 50 trees being planted in locations such as Kenya, Madagascar, Nicaragua, and others all around the world.


For each Turtle hat sold, we will donate $5 to the Cape Eleuthera Foundation, an organization that supports students and researchers working towards building a more live-able future. This foundation funds the programs of the Cape Eleuthera Island School with the mission of leadership effecting change through education, research and sustainability. A sea turtle research program is one of several other important and ongoing projects included in their marine conservation work. When we sell a Turtle Cap, the $5 we send to the Cape Eleuthera Foundation will help fund the education of future leaders in sustainability.

In early 2019, co-Founders Michael Medvedev and Peter Frelinghuysen––student-athletes at Williams College––saw an opportunity to make a difference.

The two had travelled to southern California in March 2019 to compete against west coast tennis teams. Both Michael and Peter had long and unruly hair, and the southern California sun proved a tougher opponent than it had in northern Massachusetts––wearing a hat became a match-essential. When they returned to Williams, they soon realized that they seldom left their dorm rooms without a cap––for their hair, for the sun. What had started as a functional accessory soon transformed into a deliberate style-piece. Both Michael and Peter grew their hat collections, and had fun doing it––friends and teammates would constantly ask into the designs on their caps. But something fundamental was missing: purpose.

In June, after completing the academic year at Williams, Michael and Peter combined their enthusiasm for entrepreneurship with their love of nature and concern for the environment to found Earth Caps. Since then, their commitment to fighting global warming has only grown as they have researched and learned more about the looming threat climate change poses.


Our end-goal has always been to create a cap that is carbon neutral. We are currently in the R&D phase of producing a (customizable) cap that is made out of 100% repurposed materials: a sustainable Earth Cap! Until then, we seek to lend purpose to our designs––raising awareness about global warming and its devastating effects.

Ultimately, by wearing our caps, you promote the fight against global warming and its devastating effects. Simply put: buy a cap, save the Earth.
