Where to buy solar blankets?

I believe Cabelas or possibly something like Bass Pro Shop carries them...anywhere you'd find a complete camping supply section. Many do use them, but we made the investment in Pop-up-Gizmos and were 110% pleased. They are custom sized to fit each bunkend, have whichever type of tie-downs you choose and Bob and his company stand behind the product completely. They have a regular tie-down type, the High Wind version - which we bought - and now the Super High Wind. They recently have come out with a set which fits inside the interior walls on the bunkend and look like they'd do a fine job in colder climates. Just one of the things we liked about ours was that they have a neat and tidy appearance rather than using a sportsmen type that's just a rectangle and you either have to trim it to fit or leave it as a rectangle and it may not have such a neat appearance. Suggest you investigate all your options.
