Not every athlete hits the same. For coaches holding for bigger, stronger, harder-hitting fighters, standard mitts aren't enough.

Coaches Line - Maximum Protection
The Highest-Protection Mitt in the ONX Coaches Line
The ONX Heavy Hitter Punch Mitts are the maximum-protection mitt in the Coaches Line. The larger 7.25 x 10 x 3 inch profile gives athletes a bigger target and gives coaches significantly more cushion between the strike and the hand. The multi-layer impact foam disperses force on contact, reducing sting and hand fatigue across extended rounds. The raised palm grip keeps the mitt stable and secure without requiring the coach to over-grip through every combination.
Built for MMA pre-fight warmups, power-focused boxing and kickboxing sessions, bare-knuckle-style striking preparation, and fight-camp coaching where impact volume is high and hand protection is non-negotiable.

Construction Detail
Built to Protect the Coach. Round After Round.
Every feature in the Heavy Hitter Punch Mitts addresses one problem: what happens to a coach's hands when they hold for a big puncher over an extended session. The foam reduces sting. The profile distributes force. The palm grip keeps the mitt controlled without the coach fighting it through every combination.
Larger 7.25 × 10 × 3 in Profile More surface area means more foam between the strike and the coach's hand. Bigger target for the athlete. More protection for the coach.
Multi-Layer Impact Foam Stacked foam system disperses force across the full striking surface. Reduces sting, cuts harsh feedback, and keeps the coach's hands functional through long rounds and multi-session fight camps.
Raised Palm Grip Creates a natural grip point inside the mitt. Less effort to hold securely. Less hand strain per round - critical when holding for power hitters at high volume.
Coach-Controlled Fit Stays stable in the hand through combinations without the coach needing to overgrip. When the mitt doesn't fight back, the coach can focus on timing, target placement, and athlete feedback.
PU Leather Composite Exterior Rip- and tear-resistant surface designed for repeated heavy impact. Water-resistant external protection. Built for daily gym use without breaking down.
Moisture-Wicking Interior Helps manage sweat and protect the internal foam system during high-output training. Extends product life through repeated daily use.

Frequently Asked Questions
Heavy Hitter Punch Mitts - Common Questions
What makes the ONX Heavy Hitter Mitts different from standard focus mitts?
The Heavy Hitter Mitts have a significantly larger profile - 7.25 in wide x 10 in long x 3 in thick - compared to a standard focus mitt. That larger build gives athletes a bigger striking target and gives the coach more foam and surface area between the punch and the hand. They are built specifically for coaches holding for bigger, harder-hitting athletes where standard mitts provide insufficient protection.
How do the Heavy Hitter Mitts compare to the ONX Air Mitts and Panther Mitts?
The three mitts serve different roles in the Coaches Line. The Air Mitts (10 oz) are the lightweight speed option for accuracy, timing, and fast combinations. The Panther Mitts (12 oz) are the technique mitt - curved catching surface, denser foam, built for punch turnover and realistic feedback. The Heavy Hitter Mitts (15 oz) are the power option - maximum profile, maximum foam, built for big hitters, fight camps, and high-impact pad rounds.
What disciplines are the Heavy punch Mitts built for?
These mitts are built for MMA pre-fight warmups, boxing and kickboxing power rounds, Muay Thai striking sessions, bare-knuckle-style striking preparation, and any fight-camp environment where athletes generate serious impact. They are ideal for coaches working with heavyweight athletes, power punchers, or high-volume training programs.

FIGHT-CAMP CONSTRUCTION Premium PU composite exterior, reinforced high-impact stitching, and moisture-wicking interior built to handle relentless daily training volume.
Some athletes hit with real power. Holding for them with a standard mitt isn't protection - it's just tolerance. I designed the Heavy Hitter Mitts with a larger profile and thicker foam so the coach isn't fighting the tool. When the mitt absorbs the impact correctly, the coach can focus on the athlete. That's when the real coaching happens.
Every ONX product starts with keeping the people in the gym healthy - including the coaches. The Heavy Hitter Mitts are built to protect the coach's hands through high-impact rounds, fight-camp volume, and pad sessions with athletes who generate real power. The larger profile distributes force across a bigger surface. The multi-layer foam reduces sting and harsh feedback. The raised palm grip keeps the mitt secure without forcing an over grip. Built for MMA, boxing, kickboxing, Muay Thai, and any striking environment where power is part of the program.

When an athlete hits hard, the coach pays for it — in the hand, through the wrist, round after round. Standard mitts spread that force across too small a surface. The Heavy Hitter Mitts were built with a larger profile and multi-layer foam specifically to change that math. More surface area. More absorption. Less damage to the coach's hands over the course of a training camp. That's the whole point.
