Hayabusa S4 PU Leather Boxing Gloves for Men & Women - 14oz Training

Our review of the Hayabusa S4 boxing gloves finds them to be a solid entry-level option for beginner and recreational fighters who want reliable protection and a comfortable fit without a premium price. The biggest reason to buy is the balanced combination of cushioned knuckle protection and splinted wrist support, which makes these gloves feel secure from the moment they are laced up. They are built with PU leather and a mesh palm that stands up to regular training, so someone starting boxing, kickboxing or martial arts will get dependable value while they improve technique.

Key Features

• PU leather construction: Provides a durable outer surface that resists wear from heavy bag and pad work while remaining easy to clean.
• Mesh palm and nylon lining: Promote breathability and faster drying between sessions so the gloves feel fresher after intense workouts.
• Pre-curved ergonomic pocket: Encourages proper fist closure and alignment to reduce hand fatigue and help with consistent striking form.
• Single strap with splinted wrist support: Delivers a secure fit that limits risky wrist bends and improves overall support during sparring and heavy hitting.
• Padded knuckle protection: Plush cushioning foam protects knuckles for beginners learning punches and combinations on bags and mitts.
• Multiple weight options: Available in 10 oz, 12 oz, 14 oz, and 16 oz so users can match glove weight to training or sparring needs.

Who It's For

The S4 is best suited to beginners and recreational athletes in boxing, kickboxing, Muay Thai and mixed martial arts who need dependable protection and a tailored, comfortable fit. It works well for training sessions on heavy bags, pads, and light sparring when paired with proper hand wraps.

Those who should look elsewhere include fighters seeking premium leather, advanced competition gloves, or a very wide internal fit; some reviewers report a snug fit for larger hands and others expect longer-term durability from higher-end materials.

Pros & Cons

Cons
