I have the same 2x brought me the sail for the twin strollers ABC Design Zoom. You never get the sails on the rearward tub really good fixed (ie, at least I do not). For the front child is doing well, as with any normal stroller. And like many other write - only if you follow suit, the rubber again. In the buggy variant I have similar problems. In addition, I have the awning brought not only as protection from the sun, but also to time to offer my children a break from the exciting new world and to help them fall asleep. Unfortunately, they always look past the sail and can all too easily beisete push it myself. And then it's back to the exciting world and the shouting starts again. But you can both sail side sew together and then stretched over the stroller, so they give a very, very good sun protection from, better than the umbrellas on the ABC Design Zoom and also the blinds is with towels left and right again guaranteed.
