Frequently Asked Questions

What is the difference between the Hayabusa S4 and T3?

The T3 uses Vylar engineered leather and features the Dual-X double-strap closure system. The S4 uses Maya Hide leather with a single-strap closure and triple-splint wrist support. The T3 is Hayabusa's flagship model with their most advanced wrist support; the S4 is a step down in price while still delivering pro-level protection. Both are excellent choices for serious training.

Are the S4 gloves good for both bag work and sparring?

Yes. The S4 is designed as an all-round training glove. Use 10–14 oz for bag and pad work, and 16 oz for sparring. The multi-layer foam padding and triple-splint support make it equally effective for both applications.

Do the Hayabusa S4 gloves come in lace-up?

Yes — the Hayabusa S4 Lace Up Boxing Gloves are available separately in 8–16 oz for a custom-fit competition closure. The standard S4 uses a hook-and-loop strap closure for everyday training.

How do I size the S4 boxing gloves?

S4 gloves are sized in oz: 10 oz (X-Small), 12 oz (Small), 14 oz (Medium), 16 oz (Large). For most adults doing bag/pad work, 12–14 oz is ideal. For sparring, 16 oz is the standard recommendation.
