Mostly soap, I think.

One of the best trucker hats that I have ever had. The quality is hand downs amazing. The only negative thing I have to say is that my adjustable plastic thing in the back broke after like 2 days (there's like a fissure running horizontally in middle of it), but it still wearable. Oh yeah..for some reason this hat makes my ears stick out like dumbo for some reason lol..probably because the sides are wider than most other trucker hats.
