Whenever I see a Hawaiian shirt I assume “gun”.

Or a sleeveless vest. Why in the heck else would anyone where a sleeveless vest?

To cover without sweating.

I Like a sleeveless T with an open light long tailed plaid shirt in the Dog days of Tx
Keeps the sun off, not to hot.

Depends on the sleeveless vest. In colorado it is not uncommon to have a hiking vest with a light jacket over it instead of a heavy coat in the fall or even some winter days.
