Hayabusa S4 PU Leather Boxing Gloves for Men & Women - Training Fit

In this review of the Hayabusa S4 PU Leather Boxing Gloves the bottom line is simple: these are a dependable entry-level glove for beginners and regular class-goers who need protection and a good fit without a big investment. The reviewer found the gloves comfortable immediately, with a secure wrist feel and decent knuckle padding, making them suitable for pad work, bag sessions and light sparring. The construction and materials promise durability for frequent training while the pre-curved pocket and grip bar help maintain a natural fist position.

Key Features

• PU leather construction: Provides a durable outer shell that stands up to frequent bag and pad work while keeping costs moderate.
• Nylon lining: Helps the gloves resist wear on the inside and eases putting them on for repeated training sessions.
• Mesh palm: Improves breathability so hands stay drier during longer workouts and reduce break-in discomfort.
• Pre-curved ergonomic pocket: Encourages a natural fist and better hand alignment, which helps reduce hand fatigue while striking.
• Single strap with splinted wrist support: Delivers a secure fit and limits risky wrist bends during impact and sparring.
• Cushioning foam around the knuckles: Adds impact protection so beginners can develop technique with less risk of hand soreness.

Who It's For

The S4 gloves are aimed at beginners and recreational athletes - adults and youth taking boxing, kickboxing or mixed martial arts classes who need a comfortable, protective glove for training, sparring and bag work. They are a strong choice for anyone prioritizing wrist support and a glove that feels ready to train out of the box.

Those with very large hands or fighters seeking premium materials and advanced multi-layer foam systems should consider higher-end models; similarly, competitive fighters looking for specialized sparring or fight gloves may want gloves with different padding profiles or leather uppers.

Pros & Cons
