Assuming everyone should have a raincoat, we could say everyone should have its one CAIÁGUA (the Portuguese expression for “water is falling”). These colourful waterproof jackets (please interpret the word “waterproof” at a literal level) are light, comfortable and functional. This model (86,8% PVC, 6,6% cotton, 6,6% polyester) has breathing holes under the arms and at the back (in the inside), an adjustment knob at the end of the sleeve and a hyper useful inside pocket for mobile phone and wallet (there’s room enough for both of them). And I guess the following statement is obvious: you’re not going to get wet anymore.
Note: Rúben (1,98m, 82kg) is wearing a XL size Caiágua, Filipa (1,74m, how impolite is to ask a lady for her weight?) is wearing a XS Caiágua and Tomás (1,74m, 75kg) is wearing a M size Caiágua.
