Novak Djokovic will carry a 19-match winning streak into the Australian Open semifinals, along with a fully-stocked new accomplice.

The world No. 1 has debuted the new Head Djokovic Monstercombi racquet bag Down Under. The bag, which retails for $89.95, is one of four bags in the Djokovic Series, which launched globally on January 11.

The 31-inch long bag is 13 inches wide, 13 inches high, and features a large racquet compartment that can accommodate four to six racquets, as well as an additional accessory/racquet compartment that holds up to four more racquets. Two padded shoulder straps with are removable (with a pocket to store them) and a built-in shoe compartment stores worn match sneaks and sweaty socks away from racquets and grips.

Djokovic has come to the court carrying a fully packed bag—he typically carries five to seven racquets, socks, shorts, shirts, grips, at least one pair of shoes, and the Serbian flag—and he put the contents to good use in his epic 1-6, 7-5, 6-4, 6-7 (5), 12-10 fourth-round thriller over Stanislas Wawrinka. It spanned five hours and two minutes, and saw both men deplete their inner reserves and the contents of their bags.
