Hi. I was wondering if anyone can recommend a travel bag/holdall for a phil and teds navigator that will pack the buggy with both seats intact. I need to take the double for our holiday this may! ! have seen p & t do an older and newer version but it would seem from reviews that it won't fit the second seat. Just would like something to protect the buggy and keep safe as an expensive bit of kit. Daughters aged 3 and 1. Can anyone help?
