Swimwear Fabric Recommendations

Swimwear Fabric

 Whether it’s soaking up the sun by the beach with sand between your toes, poolside lounging in boho-inspired resort wear, or powering through laps in an Olympic pool, the types of materials you pick out for your swimwear garment can differ vastly.

Traditional athletic swimsuits meant for swimming or watersports are made with design and fabrics that are more technical and performance-driven, such as reduced drag in the water, whereas casual, fashion-forward swimwear such as bikinis and one-pieces are more aesthetically and design-focused.

From properties such as chlorine resistance to dye and print suitability for the hottest summer bikini, having an idea of your garment’s purpose will help during the fabric selection process as you pick out materials that will aid in its performance and wear.

In this guide, we’ll discuss the various recommended fabrics for garments from bikinis to board shorts.

Natural VS Synthetic Fibers

While natural fibers are loved for apparel such as dresses and shirts, they’re not commonly used in swimwear as they are not as long-lasting or resilient. They also tend to absorb water and get soggy and heavy when wet, leading to an uncomfortable and unpleasant experience.

Synthetic fibers are predominantly used as they have better performance qualities, abilities, and durabilities such as chlorine, saltwater, and sunlight resistance. These synthetic fabrics can also hold up more to wear and tear, which prolongs the garment’s lifespan. 

Elastane VS Spandex VS LYCRA®,
and why it’s important:

As fabrics such as polyester or nylon do not have natural elasticity in their fabric composition, these fabrics have to be blended with a stretchy material such as elastane which will provide movement, flexibility, and stretch. This allows the garment to contour to the curves of the body while allowing the wearer to remain comfortable without restriction or stiffness when moving.

Elastane: A lightweight, synthetic fiber known for its exceptional stretch and elasticity, commonly used to make stretchy clothing such as sportswear.

Spandex: An anagram of the word “expands”, which refers to the fibers’ ability to stretch and return to their original shape. Spandex is an alternative name for elastane.  

LYCRA® = A brand of elastane that was invented and patented by the company DuPont.

Although elastane’s ability to return to its original shape after being stretched is highly prized, it’s important to note that one of the downsides is that the fabric does not have the longest lifespan. Prolonged exposure to sunlight, chlorine, and saltwater can contribute to color fading, degradation and loss of elasticity. 

Swimwear properties to look out for:

  • Hydrophobic and quick-drying materials
  • Colorfast – resistance to dye fading or running
  • Four-way stretch to contour and hug the body
  • UV-resistant
  • Chlorine resistance
  • Anti-UV Finish (UPF+ resistance)
  • Drag reduction and resistance
  • Compression

Nylon-elastane Blends

The most commonly used fabric among female swimwear pieces, nylon blends are soft and comfortable with a good stretch that hugs the body well. Thin and lightweight, it offers a smooth and elegant fit, and is commonly used for outerwear, activewear and underwear due to its lightness, durability, lower price point and hydrophobic qualities.

An alternative to polyester, nylon is typically not as long-lasting and less resistant to chlorine as compared to polyester, but textile manufacturers today are coming up with innovative solutions that resist and tackle these shortcomings to rival the properties, durability, and longevity of polyester. 

Such an example is the Xtra Life LYCRA® which is specially designed to resist chlorine, heat and UV damage and last up to 10 times longer than swimwear made with unprotected spandex.


  • Resilient 
  • Able to withstand rubbing and scraping
  • Great elasticity
  • Low in moisture absorbency
  • Abrasion Resistant


  • Prone to degradation by acids, chlorine and sunlight
  • Might pill over time

Recommended for: One-piece suits, two-piece suits, bikinis,   swimming trunks

Polyester-elastane Blends

The leading fabric for competitive swimwear, polyester blend swimsuits offer chlorine and sunlight resistance and are known for being durable and long-lasting. Strong, soft, and extremely hardy, polyester blend fabrics also absorb and hold dyes well despite repeated use.

An extremely hydrophobic material that repels water, it remains a highly popular option in the industry not only for its quick-drying and resilient properties but also for its ability to withstand prolonged wear and contact with chlorine.


  • Strong and resilient fibers
  • Provides a soft and comfortable fit
  • Durable and resistant to shrinkage
  • Abrasion and pilling resistant
  • Quick-drying
  • Chlorine-resistant
  • Provides UV protection


  • Lack of breathability
  • Does not absorb moisture

Recommended for: One-piece suits, two-piece suits, bikinis, swimming trunks

PBT (Microfiber Polyester) 

Known as polybutylene terephthalate texturized, PBT fabrics are a member of the polyester family of plastic fibers. Although PBT fabrics can be used as an alternative to elastane fabrics due to their natural stretch, they are not as stretchy as elastane. 

PBT fabrics are commonly used for swimwear due to their unique recovery properties that return to their original shape after major stretch and strain, as well as resistance against the effects of chlorine and saltwater.


  • Wrinkle-resistant
  • Colorfast and resistant to UV light
  • Resistant to fading
  • Durable
  • Light and smooth
  • More resistant to wear and external factors


  • Stiffer than elastane
  • Not as stretchy as elastane

Stretch Mesh 

Characterized by its net-like open pattern, lightweight heft, permeable texture, and added elasticized property, stretch mesh fabrics are woven or knitted loosely, resulting in its open hole structure. Similar to traditional mesh fabrics, the elastic open-net fabric allows for movement and stretch to contour around the body for a good fit.

The lightweight properties and open holes provide breathable ventilation while remaining durable against ripping or tearing, making it a great choice for swimwear as it wicks moisture away quickly.


  • Allows for ventilation
  • Mildew resistant
  • Lightweight, breathable
  • Wicks sweat and moisture away quickly


  • Holes in mesh fabric can easily catch onto things and snag if not careful

A smooth-textured knit fabric, tricot is known for its resilience, breathable and quick-drying properties.

Tricot-blend fabrics for swimwear garments are mostly made with a blend of elastane, increasing the fabric’s elasticity to improve stretch abilities and movement when worn.

Conforming nicely to the body while retaining its shape, the lightweight yet durable fabric can be combined with yarns of various properties such as deodorizing or heat retention for cooler climates to create a suite of swimwear products with various advantages.


  • Durable and resilient
  • Good elasticity and shape stability
  • Crease and wrinkle-resistant
  • Breathable
  • Can be combined with other yarns for various advantages and properties

Also known as ribbed fabric, rib-knit fabrics are more durable and elastic than regular plain knits.

Rib-knit fabrics use knit and purl stitches in alternating raised and lowered rows, creating cross-grain elasticity.

Available in an array of textures and weights, the fabric’s density is determined by the closeness of the knitting stitches.

Its stretchy and elastic properties are especially favored for making elevated basics such as t-shirts.

A great option for swimwear, ribbed fabrics provide an interesting parallel line pattern with a soft feel while allowing movement and comfort.


  • Available in a wide variety of textures and weights

Nylon, also known by its chemical name polyamide (which refers to a range of polymers with repeating units linked by amide bonds) is a synthetic man-made fiber derived from petrochemicals.

Similar to polyester, it is also extensively used in the industry due to its durability and weather resistance. 

Nylon fabrics are exceptionally strong, resistant to abrasions and damage, and hold up well against chlorine and saltwater.

Stronger than polyester, nylon has a slightly lower moisture absorbency than polyester, which means that it also wears warmer and is more likely to cling on to the body when damp.

An extremely robust fabric, nylon is a great choice for making swimwear shorts that will hold up against weather and wear. 


  • Extremely durable and resilient
  • Resistant to weather and external factors


  • Can feel warm as traps moisture
  • Not breathable
  • Wears warmer than polyester

Recommended for: board shorts, swim shorts

One of the most popular materials utilized in the industry, polyester is a petroleum-derived synthetic fabric that is used for a plethora of garments and finished products such as outdoor and camping gear.

The strong fabric is highly resistant to environmental conditions, and when blended with other fabrics, it introduces attributes such as improved shrinkage, durability and hardiness. 

Polyester woven fabrics are a great choice for swimwear shorts as they resist liquids and wick moisture away rather than absorb it, which also makes them pretty resilient against stains.

Loved for their durability and low production cost, polyester and polyester blend fabrics have become the most popular synthetic and human-made materials today.


  • Wrinkle-wicking and resistant 
  • Highly durable
  • Moisture-wicking


  • Can feel warm as traps moisture
  • Not breathable
