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

In this review we test the Hayabusa S4 PU Leather Boxing Gloves to see whether they are a reliable starter glove for training and sparring. The bottom line: these gloves are best for beginners and club-class athletes who need a comfortable, protective glove that feels supportive from the first wear. The combination of PU leather, a mesh palm and a pre-curved ergonomic pocket gives a glove that performs well in mitt work, bag sessions and light sparring while offering noticeably strong wrist support and knuckle padding.

Key Features

• PU leather construction: Durable synthetic leather resists wear during high-intensity weekly workouts to extend the glove life.
• Nylon lining and mesh palm: Breathable interior materials help manage moisture and keep hands cooler during long training sessions.
• Pre-curved ergonomic pocket: The shaped interior and grip bar promote a natural fist closure and correct thumb alignment for safer striking.
• Single strap with splinted wrist support: A wide strap works with a rigid splint to stabilize the wrist and prevent risky bends on impact.
• Cushioning foam for knuckles: Multi-layer padding gives protection for beginners learning technique while still allowing good feedback on contact.
• Multiple sizes available: Offered in 10 oz, 12 oz, 14 oz and 16 oz to suit children, smaller adults and heavier training or sparring needs.

Who It's For

The Hayabusa S4 is aimed primarily at beginners and recreational fighters who want a reliable, well-padded glove for training, kickboxing, taekwondo and other striking arts. Its tailored fit and grip bar are helpful for athletes who are developing proper fist closure and need consistent wrist stabilization.

Stronger or competition-level athletes who need highly specialized sparring or heavy bag gloves might look elsewhere for advanced shell construction or premium leather. Also, those with very wide hands should try them on first since some users report a snug fit.

Pros & Cons

Pros

• Comfortable immediately with a pre-curved pocket that encourages correct hand position.
• Good wrist protection thanks to the single strap and splinted support system.
• Breathable mesh palm and nylon lining reduce sweat buildup during long sessions.
• Available in multiple weights so beginners and kids can choose appropriate padding.

Cons

• Fit can be tight for some users, so trying the glove on or choosing a larger weight may be necessary.
• PU leather is durable for a synthetic, but heavy daily use may show wear sooner than genuine leather.
