1. Happy Earth

This brand is one of my favorite. It's extremely affordable ($25 for tees) and donates half of its proceeds to various causes. Not only are no harmful dyes or animal-based products used, but the packaging it comes in is 100% recyclable. Part of their message is being "determined to stop climate change, deforestation, and ocean pollution." It's a great buy and their shirts and beanies are really comfy.
2. Ten Tree

Their message is in their name, they plant 10 trees for every purchase! So far they've planted over 25 million trees and the number goes up along with their purchases. Their purpose is to "revitalize our environment and inspire." They use coconut made buttons instead of plastic, hemp products, cork, organic cotton, recycled polyester, and other sustainable materials. Although they aren't the cheapest brand ($30-45 for tees), it's reasonably priced considering how many trees they plant for a single purchase and the quality of the product itself.
3. The Parks Apparel

Their goal is to "to create a collective consciousness of outdoor appreciation and awareness." They encourage promotion, leadership, and involvement in their cause. Their tee-shirts range from $30-40 and give off an Indie Bo-Ho vibe.

This brand donates 10% of all profits are donated to marine life. Given the word "sand" in the name, this brand is beachy with light colors for the blankets and towels. They support the Marine Conservation Institute, The Surfrider Foundation, The Pacific Marine Mammal Center, San Diego Coastkeeper, Hawaii Wildlife Fund, and Ocean Connectors. All of these ocean protecting organizations are non-profits and use Sand Cloud's donations to protect ocean wildlife.
