Genuine Leather 3-in-1 Convertible Briefcase by PROBOX

Transform your boxing regimen with the Pro Box 3-in-1 Training Bag—your all-in-one solution for mastering technique, speed, and power. Engineered with a heavy-duty leather exterior and reinforced stitching, this triple-purpose bag withstands 10x heavier strikes than standard punch bags while saving gym space. Its innovative angular structure combines three distinct training zones: a high-density foam uppercut panel for rotational strikes (perfecting hooks and uppercuts), a responsive maize core for footwork drills (enhancing agility), and a weighted base-punch zone optimized for straight punches and body shots.

Ideal for home gyms with limited floor space (measures 60″ tall when assembled), this bag eliminates the need for multiple equipment purchases. Athletes report 30% faster combo retention after switching from single-function bags due to its dynamic angle adjustments (15° forward tilt for defensive practice). The moisture-wicking lining prevents sweat buildup during 45-minute+ sessions, while the included anti-tip bracket ensures stability during power rounds.

Perfect for:
✓ Sparring preparation with realistic recoil feedback
✓ Sport-specific conditioning using adjustable resistance bands
✓ Injury prevention through controlled impact zones

Compared to traditional heavy bags that limit movement patterns, this NSF-certified training tool adapts to every phase of fighter development—from beginner stance drills ($299 value) to advanced defensive footwork simulations. Comes with a proprietary quick-dry liner system that reduces maintenance time by 40% versus standard sand-filled bags.
