Hayabusa S4 PU Leather Boxing Gloves for Men & Women 10-16oz

In this review of the Hayabusa S4 PU Leather Boxing Gloves, the bottom line is clear: these are a reliable beginner training glove that balances protection and comfort for striking practice. Designed for men, women and kids across 10 oz, 12 oz, 14 oz, and 16 oz sizes, the S4 stands out for its protective wrist support and immediate comfort from the moment it is put on. The glove's PU leather build, mesh palm and nylon lining make it suitable for high-intensity sessions while remaining an affordable entry point into glove ownership.

Key Features

• PU leather construction: Durable outer material offers abrasion resistance so the gloves hold up through frequent training sessions.
• Pre-curved ergonomic pocket: Promotes natural fist closure and alignment to help maintain proper technique while punching.
• Mesh palm and nylon lining: Improves breathability and comfort so hands stay cooler during long pad or bag work.
• Single strap with splinted wrist support: Delivers secure closure and stabilizes the wrist to reduce risky bends and impact stress.
• Padded knuckle protection: Cushioned foam across the striking surface helps protect knuckles during repeated hits.
• Multiple weight options: Available in 10 oz through 16 oz sizes to match training, sparring, and user size needs.

Who It's For

The S4 is aimed at beginners and casual trainees who need an affordable, comfortable glove for training, sparring, kickboxing, MMA, Muay Thai and general striking drills. It particularly suits users who value wrist support and a glove that feels comfortable immediately thanks to the pre-curved pocket and grip bar.

Experienced fighters or athletes seeking premium leather, advanced multi-layer foam systems, or a very roomy fit may want to consider higher-end options; some users report a snug fit, so those with wider hands should try sizing up or test fit before committing.

Pros & Cons

Pros

• Comfortable fit from first use with a pre-curved pocket that aids proper fist formation.
• Strong wrist stabilization from the single strap and splinted support reduces injury risk.
• Good ventilation for the price thanks to the mesh palm and nylon lining.
• Affordable and versatile across training and multiple striking disciplines.

Cons

• Fit can be snug for some users, especially those with wider hands, so sizing matters.
• PU leather is durable for entry level but will not match the longevity of premium genuine leather.
