First I have to say - I love the size! When you have two children both under five this size bag is just must-have. Also the colours are lovely, fresh, bright, perfect for summer. But in my case the most important thing is detachable stripe which could give me hands free during a walk with children. I am sorry but there is no detachable stripe! You get what you see on pic. That's all.
UPDATE - after a week of using zip broken... had to sent it back.
