Hayabusa S4 Leather Boxing Gloves for Women & Men - Wrist Protect

Our review of the Hayabusa S4 Leather Boxing Gloves looks at whether these gloves are a good fit for beginners who want a leather training glove with solid wrist and hand protection. The bottom line: these gloves are best for new boxers or fitness boxers who value a pre-curved, ergonomic fit and clear wrist support, with the main reason to buy being the combination of a natural knuckle position and targeted thumb protection that reduces soreness during mitt work and bag sessions.

Key Features

• Pre-curved natural fit: The glove shape keeps the hand in a comfortable striking position to reduce fatigue and improve punch form.
• Ergonomic thumb pocket: A designed thumb and hand pocket reduces the risk of thumb jams and helps maintain a secure fist when striking.
• Microfiber thumb: Built-in microfiber on the thumb provides a quick, convenient way to wipe sweat away without interrupting a session.
• Full mesh palm: Breathable palm construction helps keep hands cooler during longer training sessions and reduces sweat buildup.
• 100% genuine leather: Leather construction with detailed stitching aims to deliver a durable glove that stands up to regular training.

Who It's For

The Hayabusa S4 gloves are best suited to beginners and recreational trainees who want the feel and durability of leather with features focused on hand and wrist protection. They work well for people training on heavy bag, pads, and light sparring where a pre-curved fit and thumb protection matter most.

Those who should look elsewhere include fighters who need a very roomy or soft break-in fit out of the box, or advanced competitors seeking highly specialized sparring gloves. Some buyers report a snug fit or early wear in a few cases, so users prioritizing a looser immediate fit or maximum long-term durability may prefer a different model.

Pros & Cons

• Comfortable pre-curved shape reduces hand soreness across training sessions.
• Microfiber thumb and mesh palm add practical sweat management and breathability.
• Genuine leather and detailed stitching provide a solid build for typical beginner use.

Cons

• Fit can be on the snug side for some users, and a minority report durability concerns after heavy use.
