Quick Definition
A wrestling singlet is a one-piece, tight-fitting uniform made of stretch fabric, usually spandex or nylon, that covers a wrestler’s torso and upper thighs while leaving the arms and legs completely free.
What is a wrestling singlet?
A wrestling singlet is the standard uniform for amateur wrestling, worn at every level from youth tournaments to the Olympics. Its defining trait is the one-piece construction: a stretch-fabric garment with shoulder straps, a snug torso panel, and leg openings that end at the upper thigh, all sewn as a single piece rather than a separate top and bottom.
The tight fit isn’t a style choice. Grasping an opponent’s clothing is illegal in every style of amateur wrestling, and loose fabric still gets snagged by accident during a scramble even when nobody means to grab it. A singlet solves that by leaving nothing to grab. The same tight cut lets a referee track exactly where a wrestler’s shoulders and hips are relative to the mat, which matters for calling near-falls and pins.
Singlets became standard in U.S. college wrestling in the late 1960s, after the NCAA banned shirtless competition, which had previously been common alongside trunks and tights. The word itself borrows from a British term for a sleeveless undershirt.
The three singlet cuts
Singlets come in three recognized cuts, and the difference comes down to how much fabric covers the chest, sides, and back.
By far the most common is the high cut, which rises close to the armpits and covers most of the chest. It dominates high school and collegiate folkstyle wrestling, and it’s the only cut permitted for men at international events. One step down is the FILA cut, named for wrestling’s former international governing body: still chest coverage, just without climbing as high under the arms. Then there’s the low cut, which uses the least fabric of the three and drops toward the middle of the abdomen with a single thin strap up the back. Olympic and World Championship rules no longer allow it, so these days it mostly shows up in practice rooms instead of on a scoreboard.
There’s also a women’s cut, built on a different pattern through the torso and hips rather than a scaled-down men’s high cut.
Wrestling singlet vs. unitard vs. two-piece uniform
Outside the sport, people often reach for the wrong word. A singlet gets called a “unitard,” or less charitably a “onesie,” often enough that the National Wrestling Hall of Fame has written about the mix-up.
The distinction is straightforward once it’s laid out. A unitard is the broader category: any skintight, one-piece garment, typically running down to the ankles and sometimes including sleeves, worn in gymnastics, dance, and acrobatics. A singlet is a short-legged unitard built specifically for wrestling, stopping at the upper thigh instead of the ankle. Every singlet counts as a unitard; not every unitard is a singlet.
The two-piece uniform is a newer wrinkle. NFHS rules now permit a fitted compression top paired with compression shorts as a legal alternative to the one-piece singlet, an option Michigan’s high school athletic association confirmed for the 2025-26 season. It’s a split version of the same one-piece idea rather than a new garment family, and it’s gaining ground at the high school level.
| Garment | Coverage | Where it’s worn |
|---|---|---|
| Singlet | Torso to upper thigh, one piece | Wrestling competition, all levels |
| Unitard | Torso to ankle, sometimes to wrist, one piece | Gymnastics, dance, acrobatics |
| Two-piece uniform | Compression top plus compression shorts | High school wrestling, where NFHS permits it |
What’s worn under a wrestling singlet
There’s no single rule, and it varies by level. Compression shorts are a common choice today, since they add coverage without bunching under the tight singlet fabric. Some younger wrestlers wear a jockstrap and cup, particularly in youth leagues that require it, while loose boxers are generally discouraged since they bunch up under the fabric. At the adult level, plenty of wrestlers wear nothing underneath at all, which is legal in most competitive settings for men. Female wrestlers typically wear a sports bra along with whatever compression layer they prefer.
Why the term comes up in MMA
A singlet never makes it inside a cage, but the term comes up constantly in MMA coverage anyway. Many fighters wrestled competitively, in high school, college, or internationally, before moving into MMA, and commentators frequently point to that background to explain a fighter’s takedowns or mat control. Broadcast graphics and fighter profiles often cite wrestling credentials like “state champion” or “All-American,” and archival photos from that period typically show the fighter in a singlet. Recognizing the uniform, and what those credentials actually represent, makes that kind of shorthand easier to follow.
Frequently Asked Questions
What’s the difference between a singlet and a unitard?
A singlet stops at the upper thigh and is built for wrestling. A unitard is the broader category of skintight one-piece garments and typically extends to the ankle. Every singlet is technically a unitard; not every unitard is a singlet.
Can you wrestle without a singlet?
Not in sanctioned competition. NFHS, NCAA, and UWW all require a singlet-style uniform, either the traditional one-piece or, where a governing body permits it, an approved two-piece compression alternative. Practice sessions may allow more flexibility depending on the program.
Why are wrestling singlets so tight?
The tight fit prevents an opponent from grabbing loose fabric, since grasping a wrestler’s clothing is illegal in every style of amateur wrestling. It also gives referees a clear view of body position for scoring.
What material are wrestling singlets made from?
Most are a stretch blend of spandex, also called elastane, with nylon or polyester. The blend provides four-way stretch and holds its shape through repeated matches.
Are two-piece uniforms replacing singlets?
Not entirely. NFHS and other governing bodies now permit a compression top-and-shorts alternative, and it’s gaining ground at the high school level, but the traditional singlet remains standard, especially internationally.
