Reblogged because fanon is pervasive. But as you can see from these panels taken from volumes 12, 13, and 33, Luffy does indeed trust others than Nami with his hat.
As mentioned before, I personally don’t mind Luffy/Nami at all. I’m just pedantic about canon – and I don’t like the implication that Luffy doesn’t trust the rest of his crew as much as he trusts Nami. However, as pointed out by plothooksinc in this post, Nami’s still the only one that Luffy has given his hat to for comfort. That’s valid.
