MMA Equipment Rules Explained (Gloves, Hand Wraps, Attire & Safety)

Whether you’re a new fan or a coach prepping athletes, this guide gives MMA equipment rules explained in clear, practical terms. We cover exactly what fighters can wear, how hand wraps must be applied, what’s allowed for gloves, and why mouthguards, groin protection, and even hair ties are regulated under the Unified Rules of Mixed Martial Arts followed by the UFC and most major commissions. Where policies differ by location, we note the commission examples so MMA equipment rules explained stays accurate and evergreen.

The essentials at a glance (what every fighter must wear)

Under the Unified Rules, athletes must have an approved mouthpiece, sanctioned gloves, and appropriate trunks/shorts (plus a groin protector for men). Female competitors must wear a form-fitting rash guard and/or sports bra on the upper body; loose tops and breast protectors are not allowed. No jewelry, no cosmetics on the body (facial makeup at the commission’s discretion), and no shoes inside the cage. Hair must be secured safely with no hard objects. That’s the core of MMA equipment rules explained before we dig deeper.

Mouthpiece: mandatory, with a specific procedure

The round cannot begin without a mouthguard. If it’s dislodged, the referee calls time and replaces it at the first safe moment; purposely spitting it may bring a point deduction.

Hand wraps: material limits and how inspectors check them

Commissions tightly regulate wraps to prevent hard casts and keep both athletes safe. The Unified Rules (July 2024) specify:

• Gauze: up to 1 roll per hand, no more than 2 inches wide x 15 yards long.
• Tape: up to 1 roll per hand, no more than 1.25 inches wide x 10 feet long.
• Tape may pass between fingers but not cover knuckles; wraps must not exceed the wrist line of the glove. A single layer of elastic/flex tape may be applied over the completed wrap. Approved brands may vary by commission. Inspectors watch the wrapping and initial the finished wraps before gloves go on.

State rules echo this with their own limits. For example, Nevada caps each hand at soft gauze (commonly 2″ wide up to 30–40 yards depending on rule version) and restricts athletic tape lengths—illustrating that local texts may vary while following the same safety intent.

Gloves: ounces, fit, and what’s changed recently

Historically, the UFC and most pro bouts use open-fingered gloves in the 4–6 oz range for competition; amateurs often use slightly heavier gloves. The Unified Rules don’t fix a single ounce number for all promotions but require commission-approved gloves in good condition.

Design updates and reversions you should know

In 2024 the UFC announced and debuted redesigned official fight gloves (“3EIGHT/5EIGHT”), citing features like 3–4.9 oz weights (size-dependent), curved wristbands, changed seam placements, and new padding—aimed partly at reducing eye pokes and hand injuries.

By late 2024–early 2025, after mixed fighter feedback, the UFC reverted to the previous glove design for events, confirming a return to the old model moving forward. That history matters for coaches and cutmen tracking fit and taping habits, but it doesn’t change the regulatory bottom line: gloves must be commission-approved on fight night.

Petroleum jelly (Vaseline) and corner supplies

Only an approved cutman or licensed cornerman may apply petroleum jelly (or a similar substance) between rounds and only to the face. Commissions ban foreign substances that make grips slippery on other parts of the body. This small rule significantly affects grappling safety and is a key detail in MMA equipment rules explained.

Joint/body coverings, sleeves, and supports

• No taping or bracing on the upper body (beyond the hands).
• Soft neoprene sleeves may cover the knee and/or ankle only—no padding, Velcro, plastic, metal, ties, or anything that could create an unfair advantage.
• No shoes in the cage/ring.

These details are often overlooked, but inspectors regularly check them in the locker room.

Trunks, rash guards, colors, and corner identification

Shorts must be above the knee (hem may not extend below the knee) and must avoid pockets, zippers, or exposed Velcro. Athletes are distinguished by corner color (red or blue), including optional glove color/taping to aid officials and broadcasters. Female attire is specified as snug, short-sleeved or sleeveless tops; men are bare-chested.

Practical checklist — MMA equipment rules explained

• Bring approved: mouthguard, commission-approved gloves, shorts/trunks; men must bring a groin protector.
• Wraps: stick to the Unified Rules lengths; keep tape off knuckles and below the glove wrist line. Have wraps inspected and initialed.
• No shoes, no jewelry, hair secured with soft ties only.
• Vaseline only by the cutman/cornerman between rounds and only on the face.
• Expect local nuances: Nevada and other commissions publish their own hand-wrap caps and housekeeping details—always check the host commission.

FAQ — MMA equipment rules explained

• What glove size is “official” in the UFC?
  Competition gloves generally fall in the 4–6 oz range, but the promotion uses commission-approved models. The UFC’s 2024 redesign (3EIGHT/5EIGHT) briefly changed specs before the organization reverted to the prior glove design in 2024–25.
• Can fighters wear knee or ankle sleeves?
  Yes—soft neoprene sleeves only, with no padding/hard parts. No sleeves on elbows or shoulders.
• Can women wear a chest protector?
  Under the Unified Rules, loose breast protectors are not allowed; the requirement is a form-fitting rash guard and/or sports bra. (Always verify with the local commission’s adoption and any promotion-specific uniform policies.)
• Why are wraps and Vaseline so tightly controlled?
  To prevent hard-casting the hands and to stop unfair slicking—both are critical for safety and competitive equity.
