Fabric finished with formaldehyde
"Good looking hat. The ONE thing in the world I’m extremely allergic to is formaldehyde. These hats are made in china and vietnam and the fabric is finished with formaldehyde. Why… no reason for it and i’m sure that new era has had others with this problem. Had skin issues for a few days. The wife soaked the hat in detergent and water but still, just stop finishing the product to stiffen it up."
