What Is The Best Fabric For A Swimsuit? - Water Sports Haven

1. MicroTan® Fabric by BetterTan

BetterTan's MicroTan® fabric takes swimwear comfort to a whole new level. Designed with thousands of tiny micro-perforations, it lets sunlight pass through for a gradual tan while still providing full coverage.
Made from a blend of 85% polyamide and 15% elastane, this fabric combines softness, stretch, and durability, ensuring it moves seamlessly with your body while maintaining its shape over time.
Let’s dive into why MicroTan® stands out with its softness, quick-drying ability, breathability, and UV protection.
Softness
Comfort is key, and MicroTan® delivers. The polyamide-elastane blend creates a smooth, soft texture that feels great against the skin. Whether you're splashing in the waves or lounging on the sand, the fabric minimizes irritation and chafing, making it perfect for long, active beach days.
Unlike some swimwear that can feel stiff or scratchy, MicroTan® is designed to stay flexible and supple, moving effortlessly with your body for all-day ease.
Quick-Drying Performance
One of the standout features of MicroTan® is its ability to dry up to 7 times faster than traditional swimwear. Thanks to its enhanced air circulation, you won't have to deal with that damp, uncomfortable feeling after a swim. Instead, you can stay dry and comfortable, even during long days by the water.
Breathability
The micro-perforations in the fabric aren't just for tanning; they also improve airflow. This means less heat and moisture buildup, keeping you cool whether you're playing beach volleyball, strolling along the shore, or relaxing by the pool. The increased air circulation helps your body naturally regulate its temperature, even during extended wear.
UV Protection
MicroTan® provides UV protection similar to SPF 8–15. It allows UVA rays to help you tan while blocking most UVB rays, offering a balance of protection and tanning benefits. Independent testing, based on AS/NZS 4399 standards, confirms this performance.
It’s worth noting that double-lined areas, like straps and elastic sections, allow less sunlight through, which might result in slight tan lines. To achieve a more even tan, try repositioning straps occasionally while in the sun.
2. Polyester Blends
Building on BetterTan's cutting-edge MicroTan® technology, polyester blends continue to be a dependable choice for all-day swimwear comfort. Over time, polyester blends have seen major advancements. Today’s polyester is softer and offers a pleasant feel for long periods of wear, though it still doesn’t match the plushness of nylon.
3. Nylon
Nylon stands out as a go-to material for swimwear, thanks to its blend of toughness and comfort - perfect for long beach outings or poolside lounging.
Softness
The smooth, silky texture of nylon feels gentle on the skin, even after hours of wear. It’s also easy to slip on and off, whether dry or wet, making it a practical choice for swimwear.
Quick-Drying Performance
While nylon doesn’t dry as fast as some modern quick-dry fabrics, it still beats cotton and heavier blends. After a swim, it might stay a little damp but dries naturally with time - ideal for relaxed days at the beach when you’re not in a rush.
Breathability
Nylon allows for decent airflow, helping to keep you comfortable as you wear it. However, the level of breathability depends on the tightness of the weave. Tighter weaves make the fabric more durable but can slightly reduce ventilation.
UV Protection
Dry nylon typically offers modest sun protection, with UPF ratings ranging from 15 to 20. However, its effectiveness drops when wet, as stretched fibers let more UV rays through. To stay protected during extended sun exposure, don’t forget to apply sunscreen to areas not covered by the fabric.
These features make nylon a reliable and versatile choice for swimwear, offering a balance of comfort, performance, and practicality.

4. Spandex/Lycra

Spandex, also called Elastane or Lycra, is a synthetic fiber that stands out in swimwear due to its incredible stretch and fast-drying abilities. Its unique property of stretching extensively while snapping back to its original shape makes it essential for swimwear designed to handle active water use. These qualities ensure swimwear remains snug and functional, even during intense activities.
Quick-Drying and Stretch Capabilities
Spandex is not only highly stretchable but also dries quickly, making it a go-to material for performance swimwear. It can stretch up to 500–610% of its original length without tearing and instantly return to its initial shape. When combined with other quick-dry fibers, its ability to repel water becomes even more effective.
"Elastane fibres can be stretched about 500–610 percent beyond their original length without breaking and quickly return to their original length and shape. Elastane is lightweight and cool; it's also resistant to deterioration from body acids; and it is easily cleaned and quick-drying."
This combination of extreme elasticity and efficient moisture management makes spandex a top choice for swimwear that needs to perform under demanding conditions.
Fabric Comparison: Pros and Cons
Choosing the right swimwear fabric often comes down to weighing its strengths and weaknesses. Each material offers unique advantages, but some trade-offs can influence how well it performs for your needs.
MicroTan® fabric is a standout option for its tan-through design and fast-drying capabilities. It’s perfect for reducing tan lines and staying comfortable during long wear. However, its advanced technology comes at a higher price and requires extra care compared to standard fabrics.
Polyester blends are known for their durability and resistance to fading caused by chlorine and saltwater. These fabrics hold their shape well, making them a great choice for frequent swimmers. On the downside, they take longer to dry and may not be as breathable as newer synthetics.
Nylon provides a lightweight and smooth feel with decent stretch. While comfortable, it’s less resistant to chlorine and UV exposure, which can lead to fading and wear over time.
Spandex/Lycra shines in flexibility and shape retention, offering excellent stretch that supports a full range of motion. When blended with other materials, it dries faster, but pure spandex is more vulnerable to pool chemicals and sunlight, which can shorten its lifespan.
Here’s a quick breakdown of these fabrics and their best uses:
| Fabric Type | Key Strengths | Main Weaknesses | Best For |
|---|---|---|---|
| MicroTan® | Tan-through, fast-drying, great for UV exposure | Higher cost, needs special care | Tanning and quick-dry needs |
| Polyester Blends | Durable, colorfast, chlorine resistant | Slower drying, less breathable | Frequent swimming, long-term use |
| Nylon | Smooth feel, lightweight, good stretch | Prone to chlorine and UV damage | Casual swimming, everyday comfort |
| Spandex/Lycra | Flexible, retains shape, supports movement | Sensitive to chemicals, shorter lifespan | Active water sports, snug fit |
This table highlights how different fabrics align with specific swimwear needs. If you prioritize tanning and quick drying, MicroTan® is a clear winner. For durability on a budget, polyester blends are a reliable choice. Meanwhile, nylon and spandex blends offer comfort and flexibility, making them ideal for casual or active water activities.
