Hayabusa S4 PU Leather Boxing Gloves for Training & Sparring Sports

In this review the Hayabusa S4 PU Leather Boxing Gloves are evaluated as an entry-level option for new fighters and fitness trainees. The biggest reason to consider them is the combination of immediate comfort and wrist protection: the gloves feel supportive the moment they are put on and use a single strap with splinted wrist support to limit risky bends. They suit routine training, pad work and light sparring across striking arts while offering the durability expected from PU leather and a nylon-lined interior.

Key Features

• PU leather construction: provides a durable outer surface that stands up to regular training and is easier to maintain than many fabric-only gloves.
• Nylon lining and mesh palm: improve breathability and comfort during high-intensity workouts to reduce sweat buildup.
• Pre-curved ergonomic pocket: promotes a natural fist position for better technique and reduced hand fatigue during mitt and bag work.
• Single strap with splinted wrist support: secures the glove and minimizes risky wrist bends, offering confidence when striking.
• Padded knuckle protection: cushioning foam protects the knuckles for beginners developing form and impact tolerance.
• Multiple weight options: available in 10 oz, 12 oz, 14 oz and 16 oz to match training, sparring, and hand size needs.

Who It's For

The Hayabusa S4 gloves are best suited for beginners and recreational athletes who need a comfortable, protective glove for classes, bag work, and occasional sparring. They are a practical choice for adults and teens starting boxing, kickboxing, Muay Thai, taekwondo or general striking conditioning thanks to the padded knuckle area and wrist support.

Those with larger hands or who require a very wide fit may find the sizing a bit snug, and advanced fighters who demand high-end leather or specialized multi-layer foam systems should look at premium models instead. Durability reports are generally positive, though some users note a break-in period before the gloves reach peak comfort.

Pros & Cons

Pros

• Comfortable fit out of the box with a pre-curved ergonomic pocket that aids fist closure.
• Reliable wrist security from the single strap and splinted wrist support for safer impact sessions.

• Multiple weight options let users choose for training or sparring needs.

Cons

• Some users report the gloves run a bit tight for larger hands and require a break-in period.
• PU leather is durable but not equivalent to premium genuine leather for long-term heavy use.
