Hayabusa S4 PU Leather Boxing Gloves for Training - Beginner

In this review the Hayabusa S4 PU Leather Boxing Gloves stand out as a practical first glove for people starting striking sports. They are aimed at beginners and casual trainers who want a glove that feels supportive immediately, with the single biggest reason to buy being the combination of wrist protection and a comfortable, pre-curved fit that reduces hand fatigue during long bag or pad sessions. The S4 is constructed from PU leather with a mesh palm and nylon lining so it can handle regular training without feeling overly stiff.

Key Features

• PU leather construction: Provides a durable outer surface that resists wear from frequent pad and bag work while remaining affordable for beginners.
• Nylon lining and mesh palm: Improves breathability and reduces internal moisture so gloves remain more comfortable through repeated workouts.
• Pre-curved ergonomic pocket: Encourages proper fist closure and alignment so beginners can focus on technique with less hand strain.
• Splinted wrist support and single strap: Delivers a secure fit that prevents risky wrist bends and gives confidence when striking for training or sparring.
• Padded knuckle protection: Layered cushioning protects the knuckles during impact so newcomers can train more safely while they develop technique.

Who It's For

The S4 is best for beginners and recreational athletes in boxing, kickboxing, Muay Thai, taekwondo, and mixed martial arts who need an entry-level glove with solid wrist support and a comfortable fit for regular training. It covers a range of sizes (10 oz, 12 oz, 14 oz, 16 oz) so users can pick weight appropriate for bag work, mitts, or sparring.

Those with unusually large hands or who prefer premium genuine leather and advanced multi-layer foam systems should look elsewhere; some users report a snug fit at first and others seek higher-end construction for long-term daily heavy use.

Pros & Cons

Pros

• Comfortable right out of the box thanks to the pre-curved pocket and grip bar.
• Reliable wrist support from the splinted design and single strap for safer punching alignment.
• Good value for money with practical materials that stand up to regular training.

Cons

• Fit is mixed for some users and can feel tight for larger hands until fully broken in.
• PU leather and entry-level construction mean top-tier longevity may not match premium leather gloves.
