i'm looking for a good carseat cover to use while my car is parked in the parking lot. basically to prevent ithe seat/straps/buckles from getting superhot and burning my son. ideally, something quick that is easy to put on/take off. i didnt' think i really needed one of these, but now i'm realizing that i really do (i'm in Texas and it's *HOT* here!) i think i saw a reflective one at BRU..will that do the trick? any other recommendations?
