Finally bags that can be filled without the stroller (especially light) does parte backwards when the child comes out !!! I like their double attachment system that can quickly detach the bag by simply clip without touching the mounting on the frame itself, then the strap and shape of the bags are very convenient for porting once separated from the stroller. I like their part save space when not in used they not fold so K-Way Only flat black color is not very fun, but they are so convenient that I can not part with it !!
