10 Best Cotton Sports Bra 2025 in the United States

The RUNNING GIRL Sports Bra is designed to offer medium support, making it a good choice for activities like yoga, running, and gym workouts. It features a criss-cross back strap design that not only looks stylish but also provides extra support and freedom of movement. The fabric is mostly nylon with spandex, giving it a stretchy, cotton-like feel that is soft and comfortable against the skin. This combination helps with breathability and sweat-wicking, keeping you cooler and drier during exercise.

Fit-wise, the bra includes a lined shelf and removable padding, so you can customize your coverage and shape. The elastic band offers a snug but flexible hold, though it uses an elastic closure rather than adjustable clasps, which might limit size adjustments. The absence of underwire means it’s more comfortable but may not suit those needing firmer support. Because it is designed for medium-impact support, it’s well suited for workouts where moderate control is enough without restricting movement—perfect for fitness enthusiasts who want both style and function. Its versatility lets you wear it under workout tops or casual clothes.

If you require high-impact support or precise strap adjustments, this model might fall short. Also, while the fabric is durable and stretch-retentive, it’s a blend that may feel less natural than 100% cotton. This sports bra balances comfort, breathability, and moderate support with a fashionable design, making it ideal for everyday exercise and light to medium activity levels.

The Fruit of the Loom womens Front Closure Cotton Sports Bra comes in a convenient pack of three, featuring black, white, and heather grey. It's made from a blend of 95% cotton and 5% spandex, ensuring a comfortable and breathable wear, which is particularly important for active or everyday use. The fabric composition makes it soft on the skin and suitable for those with sensitivities to synthetic fabrics.

The sports bra is also unlined, providing a natural fit and feel, and it has a scoop neckline for a flattering appearance. Its front shirring detail helps with better shaping, which enhances the fit and look of the bra. The hook & eye front closure allows for easy wearing and removal, which is a great feature for those who struggle with back closures. Additionally, the bra comes with one set of removable pads enabling customization based on personal preference and desired support level.

However, there are some drawbacks. The sports bra is marked as hand wash only, which may be inconvenient for those used to machine washing their garments. The lack of underwire means it might not provide sufficient support for high-impact activities, making it more suitable for low to medium-impact sports or daily wear. This pack of bras is ideal for women looking for everyday comfort and moderate support, especially those who prefer the feel of cotton fabric.

The Fruit of the Loom Women's Built Up Tank Style Sports Bra offers a lightweight and comfortable option for those looking for a breathable cotton sports bra. Made from 100% cotton, it provides natural softness and breathability, which helps keep you cool during light activities or casual wear. The 2-ply fabric construction gives moderate support with full coverage, making it suitable for low-impact activities, although it may not be enough for high-intensity workouts.

The bra is wire-free, so it avoids the discomfort often caused by underwires, offering natural shaping without padding. Its wide straps are designed for comfort and to prevent digging or pinching, but they are not adjustable, which could be a drawback if you need a more customized fit. The pull-on closure style adds convenience but means it might be harder to put on or take off compared to bras with clasps.

The tag-free and hardware-free design enhances comfort by eliminating itchy tags or metal parts. This sports bra is a good choice if you’re seeking a simple, soft, and breathable bra for everyday wear or light exercise, but those needing strong support, adjustable straps, or padding should consider other options.
