Under-seat storage sits close to heat, sunlight, and trapped air. Once a scooter is parked, the plastic bucket can hold that heat longer than you expect.
That is why drinks, snacks, cosmetics, and small groceries can feel cooked after even a quick stop. YenDee is designed to slow that heat and make the space easier to use.
It is not a refrigerator. It is a fitted insulated liner that gives daily cargo a cleaner, cooler, more sensible place to ride.
