I am a heavy line automotive technician and this hat can hold its own. Constantly sweating, oil and fluids dripping onto it, getting knocked around and there are no signs of wear. No white discoloration from sweat stains. After a month of hard use the hat started to smell around the brim, where the hat rests against my forehead, but on Findlay's website I found cleaning instructions. Just mild soap and an old toothbrush and the hats smells as good as new. I cannot tell the difference between this hat that has been drug through the mud and a brand new "off the shelf" hat. I will be spending my hard earned money on more of Findlay's products. I am very pleased with the outcome and I have worn this hat every day for two months.

This is my work hat but I will also wear it out because how good quality it is and how well it's been holding up.
