Here at Spandex Warehouse, we’ll delve into the significance of swimsuit liners in this blog post. If you believe this information could be beneficial, we encourage you to continue reading below.

Why are Swimwear Liners Necessary?

As the summer months approach, it’s time to retrieve your swimwear from the closet to prepare for beach and poolside adventures. If you opt for skimpy and revealing swimwear, it’s essential to ensure it includes a liner for your comfort.

A swimwear liner acts as a protective barrier between your skin and the swimwear fabric. Liners come in various styles and are often crafted from different materials, so finding one that suits your needs is crucial.

Moreover, using a swimwear liner can extend the lifespan of your swimwear by shielding it from chlorine and other pool chemicals. Whether swimming or lounging by the beach or poolside, incorporating a swimwear liner can enhance your comfort.

What is a Swimwear Liner?

A swimwear liner, also referred to as a mesh liner, is the inner layer of fabric found in swimwear. It serves to provide coverage and support, typically made from a different material than the swimwear itself.

Mesh liner, as it’s sometimes called, may be either removable or sewn in place. Crucially, liners offer support and coverage for specific areas such as the bust and hips, helping to prevent chafing. Additionally, they are often constructed from materials that safeguard against harmful UV rays.

Liners are frequently employed for modesty purposes, though not all swimwear includes them, and some individuals prefer not to use liners. Determining whether a liner is necessary depends on the swimwear style and personal preference.

Why Do Bathing Suits Have Liners?

Swimwear liners serve several important purposes. Firstly, they were designed to safeguard the swimwear fabric from the harsh effects of chlorine and other pool chemicals, which can be abrasive and lead to deterioration with regular use.

Additionally, liners help maintain cleanliness by preventing oil and sweat buildup on the swimwear fabric. They also play a crucial role in extending the lifespan of swimwear by shielding it from UV rays, thus preventing color fading. Furthermore, liners offer extra coverage, particularly beneficial when wearing skimpy swimwear.

Importantly, they protect the skin from irritation caused by the constant friction of the swimwear fabric and help prevent swimsuit rash by minimizing bacterial growth in wet swimwear.

What are the Different Styles of Swimwear?

Swim Trunks

Among the most popular styles in the United States, swim trunks resemble typical shorts and are ideal for casual beach or pool wear. They come in various designs, often equipped with pockets and drawstrings for user convenience. Typically featuring mesh lining, swim trunks ensure comfort and quick drying.

Board Shorts

With a length extending above the knee and a slightly elastic waist, board shorts are favored by athletes engaged in activities like surfing and paddleboarding.

Square-Cut Shorts

Characterized by a snug fit, these shorts offer coverage from the waist down to the lower thigh, providing swimmers with flexibility and freedom of movement. Lightweight and preferred by many swimmers, they facilitate easy mobility in the water.

Rash Guard Bottoms

Also referred to as surf shorts, rash guard bottoms are tailored for surfers requiring thigh protection. Constructed from materials that shield against harmful UV rays, they ensure both performance and safety in the water.


These are skintight swimwear garments with short knees, often favored by swimmers to minimize drag while in the water. Resembling cycling bottoms but lacking the tummy cushion, they offer streamlined performance.

Swim Shirts

Serving as an upper-body counterpart to the rash guard, swim shirts shield against harsh UV rays, making them ideal for casual beachgoers and poolside loungers alike.

Wetsuits and Dry Suits

Designed for a snug fit, these suits create a seal, allowing for extended periods of immersion in the water. They are well-suited for various water sports and activities such as scuba diving, snorkeling, and surfing.

FAQs about Swimwear and Liners

Do board shorts have liners?

Board shorts, primarily used for surfing, typically include liners. These liners serve to prevent restrictions in movement while surfing. The mesh lining helps the shorts maintain their shape and prevent them from clinging to the skin when wet, offering both coverage and comfort. Made from lightweight material, the net lining ensures comfort, making board shorts suitable for activities like pool play or beach volleyball.

Do swim shorts need netting?

Netted swim shorts are designed to provide support and prevent riding up during swimming. However, some users find them uncomfortable and unnecessary, as they may restrict movement. Ultimately, whether to wear swim shorts with netting comes down to individual preference.

What is the purpose of mesh in swim trunks?

The mesh lining inside swimwear serves to provide support and comfort. Swim shorts are typically crafted from materials with a rough texture that can cause itchiness and irritation to the skin. To address this, many swim shorts feature inner mesh lining made from soft polyester.

Is the mesh liner necessary in swim trunks?

Mesh liners are included in swim trunks to cover the crotch area, providing protection and preventing chafing. Some swim trunks come with attached mesh liners, serving as a barrier on sensitive areas and offering support while swimming.

When selecting swimwear with a liner, consider the comfort it offers for a enjoyable swimming experience. This ensures comfort while swimming and eliminates worries about exposure when exiting the water, providing coverage and protecting the skin from chafing caused by friction from the swimwear.

Opting for swimwear with a liner that offers UV protection safeguards against harsh UV rays while enjoying the hot summer sun. Additionally, the swimwear liner protects the swimwear from chlorine and other pool chemicals, prolonging its lifespan for pool enthusiasts.
