What is a Singlet?
Definition and Origin
A singlet is a one-piece, sleeveless garment designed to fit tightly to the body. Traditionally, it has been associated with athletes—especially wrestlers, weightlifters, and runners. The term “singlet” often varies in meaning by region. For example, in Australia and the UK, it commonly refers to a basic sleeveless undershirt, whereas in the U.S., it is usually linked to wrestling gear.
The singlet’s history dates back to ancient Greece, where early versions of the garment were used in physical contests. The modern sports singlet emerged in the early 20th century with the rise of professional wrestling and Olympic-style events, valued for allowing unrestricted movement and reducing the chance of an opponent grabbing excess fabric.
Key Features
Singlets typically have the following characteristics:
Sleeveless, with deep armholes or racerback designs
Made from stretchy, breathable materials like spandex, polyester, or cotton blends
Tightly fitted to the body for performance and comfort
Variations for men and women, with different cuts and lengths
Types of Singlets
Wrestling Singlets
These are one-piece garments worn by wrestlers to enhance mobility and ensure fair competition by minimizing grip surfaces. Olympic regulations often require singlets with specific colors and styles. In 2025, eco-friendly fabrics and gender-neutral cuts are trending in competitive sports gear.
Athletic Singlets
Worn by runners, track athletes, and gym-goers, these singlets are lightweight and designed for breathability. The focus is on minimizing chafing and maximizing airflow. In high-performance contexts, these are often paired with compression shorts or leggings.
Casual or Fashion Singlets
Increasingly popular in streetwear and high fashion, casual singlets are used as layering pieces or standalone tops. In summer months, they become essential wear, often paired with jeans, skirts, or joggers. Designers are reinventing the classic singlet in cropped versions, oversized styles, or patterned fabrics.
Undershirts
In many regions, especially the UK, “singlet” refers to a sleeveless undershirt worn beneath a shirt to absorb sweat or provide modesty. These are typically cotton-based and offer a snug but comfortable fit.
How to Wear a Singlet: Practical Tips
For Fitness and Sports
To maximize performance, select moisture-wicking fabrics like polyester or nylon. Choose a fit that hugs the body without restricting movement. Pair your singlet with compression shorts, tights, or athletic shorts. Ensure the garment complies with any sport-specific regulations.
For Casual Wear
Opt for cotton or cotton-blend singlets in neutral or bold colors. Match with denim jeans, linen trousers, or cargo shorts. Layer under an open button-up shirt or flannel for a relaxed, effortless look. Women can pair a cropped singlet with high-waisted pants or skirts for a trendy ensemble.
For Layering
Use singlets as base layers in colder months. Layer under flannels, hoodies, or lightweight jackets. A white or black undershirt-style singlet works well under semi-sheer shirts or blouses.
Recent Trends in Singlets (2025)
Sustainability and Eco-Friendly Fabrics
Brands in 2025 are focusing on sustainable manufacturing. Organic cotton, recycled polyester, and bamboo fiber singlets are trending. Companies like Patagonia and Girlfriend Collective have introduced eco-conscious singlets with performance-grade quality.

FAQs
What is the difference between a singlet and a tank top?
A singlet is typically more fitted and performance-oriented, often used in sports, while tank tops are more loosely fitted and casual. The term “singlet” also varies by region, where it may refer to an undershirt.
Can women wear singlets?
Absolutely. Singlets are available in various styles for women—from athletic wear to fashion-forward crop tops. Many brands now offer inclusive sizing and unisex designs.

Check the care label. Most singlets can be machine washed in cold water and air-dried. Avoid using fabric softeners on performance fabrics as they may reduce moisture-wicking abilities.
