Frequently Asked Questions

What is the difference between the S4 Leather and the standard S4?

The S4 Leather uses premium cowhide leather — genuine animal leather that breaks in to your hand shape over time, developing a more personalised feel with consistent use. The standard S4 uses Maya Hide synthetic leather, which is more abrasion-resistant and easier to maintain but lacks the natural break-in and feel of genuine leather. Both share the same triple-splint wrist support and multi-layer foam construction.

Does cowhide leather require special care?

Yes. Genuine leather benefits from occasional conditioning with a leather conditioner (not petroleum-based) to prevent drying and cracking. Wipe down the exterior after sessions, allow to air dry fully, and apply conditioner every few months or if the leather feels stiff. This care routine significantly extends the glove's lifespan.

What oz should I choose for sparring vs bag work?

For bag and pad work: 10–14 oz depending on your weight. For sparring: 16 oz is the standard recommendation for most adult fighters. If you only buy one pair of S4 Leather gloves, 14 oz is the most versatile weight for daily training.

How does the S4 Leather compare to Hayabusa's T3 LX?

The T3 LX is Hayabusa's premium flagship leather glove with full-grain leather and the Dual-X double-strap closure — the most advanced wrist support system Hayabusa produces. The S4 Leather uses cowhide leather with a single-strap hook-and-loop closure and the triple-splint system. The T3 LX is the top of the lineup; the S4 Leather delivers genuine leather construction at a lower price point.
