From The Aquabats! Wiki
In 2008, the rashguard as seen on the cover of The Return of The Aquabats! became available in the online store. They are lime in color, have short sleeves, and a built in hood. They are made from
Lycra by
The Aleeda Wetsuit Company. It was announced that only 200 were made, yet they remain to be abundant at the online store after once selling out. Sizes S through XL are still available
here.
