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

In this review the Hayabusa S4 PU Leather Boxing Gloves are presented as an entry-level option built for training and sparring across striking disciplines. The bottom line: they are best for beginners and regular class-goers who want immediate comfort and reliable wrist protection without spending on top-tier leather gloves. From the first wear the gloves feel supportive thanks to the pre-curved ergonomic pocket and splinted wrist support, and the PU leather plus mesh palm promise durability and breathability for everyday sessions.

Key Features

• PU leather construction: Provides a durable outer surface that stands up to frequent training while staying easier to maintain than natural leather.
• Pre-curved ergonomic pocket: Encourages a natural fist position so users can focus on technique and feel comfortable during long mitt or bag sessions.
• Single strap with splinted wrist support: Delivers a secure closure that helps prevent risky wrist bends during punches and sparring exchanges.
• Nylon lining and mesh palm: Improve internal comfort and ventilation so hands break in and stay drier through high-intensity workouts.
• Cushioning foam and padded knuckle protection: Offer shock absorption needed for beginners to learn impact without excessive hand strain.

Who It's For

The S4 is ideal for beginners and class participants in boxing, kickboxing, taekwondo, Muay Thai and mixed striking arts who want a balanced, protective glove for training and sparring. It suits adults and youth when choosing the correct weight (10 oz, 12 oz, 14 oz, 16 oz) and is particularly well matched to those who value wrist support and a firmer, pre-curved fit.

Those who should look elsewhere include experienced fighters seeking premium leather, highly customized fit, or advanced multi-layer foam systems; also buyers with very wide hands who have reported a snug feel may prefer a roomier or different cut glove.

Pros & Cons

Pros

• Comfortable right away due to the pre-curved pocket and nylon lining, reducing break-in time.
• Strong wrist support from the single strap and splinted design improves safety while training.
• Good value for a starter glove with solid padding and protective knuckle cushioning for general striking practice.

Cons

• Fit is mixed for some users; a tighter feel has been reported by people with wider hands.
• PU leather may not match the long-term patina and longevity of premium genuine leather for heavy, years-long use.

Specifications
