Welcome to our forum.
If you were to compare energy efficiency on a Marquis vs. Arctic you would see similar numbers, if not better numbers on the Marquis.
Markee,I followed this thread out of curiosity and while I'm not saying Arctic covers are any better (I think they do a great job Marketing them), in what way(s) would you think the Marquis cover would prove out to be better? Density, fit, matierial ...? While we're at it, who makes the Marquis cover (and is it used by others)?
