Hayabusa S4 Kids Boxing Gloves for Boys and Girls - Durable Youth Fit

Our review of the Hayabusa S4 Kids Boxing Gloves finds them to be a dependable option for young trainees who need protection and a secure fit. Built with PU engineered leather, injected foam knuckle protection, and a splinted wrist padding system, these gloves prioritize safety for developing hands without feeling bulky. They are best for coached classes, home mitt work, and beginner striking sessions where wrist support and an ergonomic, pre-curved fit matter most.

Key Features

• Splinted Wrist Support: A single layer foam splint covers the wrist joint to limit awkward bends and give extra support during impact.
• High-Performance Knuckle Protection: Injection molded foam in the knuckle area cushions punches to reduce shock transmitted to small hands.
• Pre-curved Anatomical Pocket: The ergonomic pocket with grip bar and thumb position promotes correct fist closure and natural alignment for safer striking.
• Adjustable Closure System: A fully adjustable velcro strap with an elastic strip in the palm provides a lace-like fit and additional wrist stability.
• Durable Materials: PU leather construction, nylon lining and a mesh palm resist wear from regular training and help the gloves last through months of classes.
• Sweat Management: A sweat thumb helps keep moisture away from the eyes so kids can stay focused during drills.

Who It's For

The S4 gloves are aimed at younger athletes learning boxing, kickboxing, taekwondo or other striking arts who need protective padding and wrist stabilization. They work well for coached sessions, partner drills and pad work where a predictable, comfortable glove shape helps develop technique.

Parents seeking lightweight, easy-to-fit gloves for 6 oz or 8 oz youth sizes will find these practical. Serious young competitors who require competition-specific gear or adults should look at adult models instead, since sizing and padding are optimized for developing hands.

Pros & Cons

Pros

• Sturdy wrist support from the splinted padding that reduces awkward bends during impact.
• Comfortable pre-curved pocket and grip bar that help maintain proper fist alignment.
• Durable PU leather, nylon lining and mesh palm that tolerate frequent class use and sweat.
• Adjustable velcro strap with elastic palm gives a secure, lace-like fit for different hand shapes.

Cons
