Fits our Big B$#key perfectly and protects the system from the heat of our subtropical sun.

Love my purple sleeve!

Very happy with this insulating sleeve. It adds a really nice look and keeps fingerprints off the stainless steel tank. I bought the blue sleeve since I associate the color blue with water. It looks great sitting on the counter.
