DUNLOP COMFORT PRO REEL MAPA MENTAL SOBRE QUMICA ORGNICA Maps4Study. Dunlop Comfort Pro (16 1. 34mm) String Set is a premium, multifilament core surrounded by thicker fibers. This helps increase energy efficiency and gives you even more power than other multifilament strings but remains comfortable on the arm. This comfortable solid core string has a multifilament wrap for better playability. The central core is protected by a durable sheath for enhanced durability. This string is perfect for the player who wants an arm friendly string that delivers slightly more control than a multifilament. The low friction surface helps the strings snap back on contact, resulting in better spin and longer playability duration.
