This vinyl cover resists rain, snow, dust, and dirt to keep hats looking newer, longer. Going out and has a chance of rain? No problem! It folds small into a handy pocket pouch! It protect your hats from inclement weather by fitting over the hat to repel water, preventing water spots. The clear plastic is durable and fits neatly over hats. Tip: With smaller brims, you may want to order a size smaller. The crown piece is elastic and able to stretch, but the brim will run large just from the difference between a western hat and fedora. Be sure to measure the brim before ordering.
