Maybe the Omer Dahlak is good for you: it's only 1,5mm thick, with ocean blue camouflage, protection on Knees, chest and forearms. It's also cheap: about 100 euro here in Italy (surely more expensive for shipping in barbados).

PS: are those stingy bugs at the origin of your fantastic nickname? (my nickname comes from what i had for lunch the day I registered on DB)
