The  Ultra 100 v4 Britto Hearts Tennis Racquet is the result of a collaboration with artist Romero Britto. The racquet is built with a new frame geometry and thinner beam construction. FORTYFIVE° has been integrated into the lay-up for a softer, more comfortable feel along with enhanced stability. An expanded Sweet Spot Channel at the tip of the hoop adds extra power with less bulk for a sleeker, more aerodynamic look. V4.0 features the Crush Zone grommet system which compresses at impact to boost power and dwell time on strings. 

The Ultra 100 keeps the user-friendly 10.6-ounce unstrung weight, 100 square-inch head, and tapered beam design, but the thinner beam and softer feel should be a welcome addition to one of the most popular tweener frames out there. v4.0 will fit well with an advanced beginner or intermediate player with solid mechanics who wants a little more power on their shots.
