This video explains the proper installation of the Baby Bivy accessory by Chariot carriers. This child comfort accessory will insure your baby is safe and warm in the carrier.
I just mounted an older Snugride on a platform attached to the frame of my generic trailer. It has breathable pads. We don't ride on the really hot days, but it's useable all year.
@Chariotcarriers We have a CX1 and have mounted the bivy attaching it to the D-rings directly on the frame (as explained in the unuserfriendly manual - if I got right). Using the stroller wheels the angle of the bivy is too much downwards towards the seat - and we have to use a pillow underneath the bivy to get it levelled properly. Is it supposed to be so?
I bought a CX 1 and a baby bivvy and the printed install instructions are shocking. Seems strange such a high quality (and expensive) product should have such poor manual. This video is useful though
