Evans UV1 Drum Heads were designed in response to drummers complaining about their old coated heads chipping, flaking, and wearing out. The coating is applied through a special ultraviolet light-cured treatment that makes it last much longer than traditional coating methods. The texture on this 13 inch head is more pronounced than on traditional coated heads, making it easy for your brushes to create louder sweeps. The underlying single ply of 10-mil film provides plenty of durability, with dent- and stretch-resistant characteristics. It provides a warm timbre. The 360-degree technology flesh hoop sits flat on your drum so even tuning is a breeze.
