Who Are the S4 Gloves For?
The Hayabusa S4 sits in Hayabusa's mid-range — above the entry-level E1 but below the flagship T3. They target serious recreational fighters who want real leather construction without paying the T3's premium price.
Construction and Materials
Maya Hide leather with reinforced knuckle zone and multi-layer foam. The mesh palm panel allows ventilation during long rounds.
Wrist Support
Triple-splint wrist support system with a single hook-and-loop strap. For heavy sparring, some fighters prefer the T3's Dual-X for additional wrist lockdown.
How It Compares
vs E1: Better leather quality and triple-splint system vs the E1's dual-splint.
vs T3: The T3's Dual-X closure provides more precise wrist alignment. For pure bag and pad work, the S4 performs comparably for less money.
Bottom Line
The Hayabusa S4 is one of the best value boxing gloves available for fighters who train 3+ times per week and want real construction without paying flagship prices.
