The Packing Formula
Carry-On Only Travel

A Regra de Ouro

Separe tudo. Remova metade. Viagem de 7 dias: 3-4 camisetas, 2 calças/bermudas, 7 cuecas/calcinhas, 2 pares de sapato. Lave a cada 3-4 dias. Uma mala de mão (10 kg) é suficiente para 90% das viagens de até 10 dias. Bagagem despachada no Brasil: R$100-200 por trecho — economize viajando leve.

Essenciais Frequentemente Esquecidos

Carregador portátil. Medicamentos pessoais. Cópia do passaporte no email. Adaptador de tomada. Saco plástico para roupa suja. Protetor solar (especialmente para destinos tropicais brasileiros).

⚡ CalcWolf Insight

The biggest packing mistake: packing "just in case" items you never wear. Studies show travelers wear only 60-70% of what they pack. Before adding anything to your suitcase, ask: "Will I definitely wear/use this at least twice?" If not, leave it. You can buy almost anything at your destination if needed.
