This is an authentic m37 denim hat. Many reproductions are available, but the authentic uneven vertical fading and puckering have a unique and cool atmosphere. The fact that it's denim fabric from the 40s means its value will continue to rise, making it a great asset. Unlike denim pants, it can be used all seasons and with any outfit. Just wearing it gives you a great look, so I recommend it. Size 6 7/8, inner circumference approximately 58cm. My head is quite large, but it fits perfectly, so it should fit most people. The color is well-preserved as shown in the images, and unlike deadstock, it's in perfect condition with a worn-in feel. There is no damage.
