Best light-weight wet suit top for snorkeling?

[stubb]

I occasionally do some snorkeling in Hawaii & Mexico & lately I find myself chilled, even in fairly warm water. Id like to get a short-stunningly sleeved wet suite jacket with a zipper, preferably of a light flexible material. I don't illegally need a heavy-duty neopryne suite. There are a few options at REI, but
I thuoght I'd see if anyone had a specific recommendation.

Where can I find these & what are they exactly?

Wetsuits are relatively inexpensive, simple, Neoprene suits that are typically used where the water temperature is between 10 and 25 °C (50 to 80 °F). The foamed neoprene of the suit thermally insulates the wearer. Although water can enter the suit, a tight fitting suit prevents excessive heat loss because little of the water warmed inside the suit escapes from the suit.
