The covers work real well, we had some for years with the pop-up, just got one for the hybrid now (we rarely use the back end currently so only got one )
Anyway they not only help relect heat, we forgot how dark they make the tent end, In summer when the sun is up early it was nice to have.
I guess it kept out at least 15 degrees, maybe more.
anyway they have a web site
PopupGizmos He is alocal camper
and he will ship them to you. What kind of hybrid do you have? We always seem to be modifying now, adding selves, hooks, key holders, ect.
