Roger Federer Limited Edition 15 Pack Tennis Racquet Bag Two Thermoguard compartments: We put 2 Thermoguard compartments because that's what Roger asks for in the bag he carries on court. Enough room to keep up to 12 racquets protected from extreme temperatures Detachable gym sack: For sweaty clothes or for dirty shoes. We wanted to make sure the style of this bag was not affected by clay or from bad odors. Internal pockets: Intuitively designed so that Roger can keep everything he needs organized - strings, grips, or the keys to his car. Lightweight and durable nylon fabric: looks great, stays that way! Luggage grade zippers: super durable zippers, in a striking silver.
