We created the ultimate running vest to churn butter on the go. Why? Because for 80 years, we’ve taken dairy very seriously. It’s hard to just sit back and watch the… let’s say, less-than-perfect attempts on social media. So we decided to give butter-loving runners a little boost. Want to give it a try? Enter below for a chance to win your own butter churning vest. And if you don’t win, our perfectly churned butter is waiting for you in stores 😉

Ready for a butter run? A few quick tips!
To ensure the quality of your butter and your personal safety, please adhere to the following directives:
- Temperature Control: Cream is highly perishable. It must not remain unrefrigerated for more than 2 hours (this limit drops to 1 hour if the ambient temperature exceeds 20 °C).
- Activity Duration: We recommend a maximum churning session of 90 minutes. If the outdoor temperature exceeds 30 °C, we strongly advise postponing the activity.
- Preparation: Keep the cream chilled until the exact moment of departure. Use pasteurized or UHT cream and wash your hands before filling the container.
- Post-Activity: Once your butter is ready, place it in the refrigerator immediately.
