The Dreamer Design trailer is an alloy frame trailer that holds 2 children. It has a 3 point harness system to securely & safely hold each child in place. It also has room for other items such as groceries, if you decide to go shopping. It can easily convert into a stroller/jogger. It has flaps that roll down to keep rain out of the trailer if it happens to rain. It also comes with a strap for your wrist so that if you happen to fall down while jogging, the trailer won’t roll away uncontrolled.
