This is a collaboration item with CA4LA, a brand that continues to create unique hats. This crushable bowler hat returns to its original shape even when rolled up. Our focus this time was on: 1. Made in Japan 2. High-quality materials 3. Foldable 4. Can hide money Made of rabbit fur blend felt, it features an adjustable sizing slider and JAM HOME MADE eyelets on the brim. (Adjustable tape allows for up to 2cm of size adjustment) Made of lightweight, high-quality rabbit fur blend material suitable for three seasons, it also has the functionality of shape-memory wool and a foldable design, rare for a bowler hat. The brim also features Jam Homemade's iconic eyelets, making it convenient to hang on a keychain or other item when carrying it around. The ribbon knot that wraps around the hat can hide a 25-cent quarter coin. This coin is perfect for magic tricks or emergency payments. Instead of the coin loafers that are synonymous with the Ivy League look, this hat is now a coin bowler hat!
