They can't send the olympia back? That sounds like BS to me. I've returned tons of olympia stuff that didn't fit the way I wanted from online retailers. Yes, the same goes for when the sun goes down around here, especially on days in the low 90's or mid 80's. It hits the mid-low 60's very fast and if you don't have a liner with you, you'll be much colder than you'd like - particularly on the highway.
