'47 Clean Up Boston Red Sox brrr°® Contact Cooling Black x Black Tonal Color BRRR '47 CLEAN UP Worn about 3 times. Lightweight and stress-free. Comfortable for long periods of wear. I took photos to show the condition as clearly as possible. Size: Free Color: Black [From the official HP] This summer collection uses the contact cooling material brrr°® (bar), perfect for the hot season, combining functionality and comfort. It features a cool-to-the-touch feel and excellent absorbency, breathability, and quick-drying properties, making it effective against heatstroke and the heat. While comfortable for water activities and outdoor scenes, the use of ultra-thin nylon micro-ripstop fabric makes it lightweight yet tough and tear-resistant. The '47 CLEAN UP is an adjustable cap with the classic silhouette of a soft crown and curved visor. The adjustable strap and carefully designed buckle provide a great fit, and the washed finish ensures a comfortable fit. Please feel free to comment if you have any questions.
