Organic yogurt maker Stonyfield Organic and the National Park Foundation teamed up for Great Outdoors Month to launch the Explore Organically collaboration featuring limited-edition national park-themed packaging. Stonyfield Organic’s Kids’ tubes showcase three iconic national parks and share collectible national park-inspired stickers that can be redeemed while supplies last by scanning a QR code inside the box.

With its StonyFIELDS program, Stonyfield has played a part in helping more than 40 cities remove harmful pesticides from their parks and playing fields. Now, its efforts are expanding to support and preserve national parks so that generations can continue to experience them. As part of this collaboration, Stonyfield will be making a contribution of $300,000 to the National Park Foundation, and sponsoring a sweepstakes that people can enter for a chance to win a trip for four to a national park.
