Bamboo blend trench terry fabric double layered. Wear it slouchy or flip the brim for a classic toque vibe.
Measurements are from FLAT fabric. Your head should measure slightly larger than the fabric or it will be too big. Many adults choose to size down to the youth/small adult size. I probably even recommend it unless you truly have a large head like me in the pics :P
