Exploring The Zoggs Sustainable Ecolast+ Swimwear Fabrics
1. ECONYL Regenerated Nylon
Introduced by Aquafil in 2011, ECONYL takes waste materials and turns them into high-performance swimwear fabric with the same quality as virgin nylon.
This process is not just efficient - it saves around 70,000 barrels of crude oil for every 10,000 tons produced. The raw materials? Discarded fishing nets, fabric scraps, old carpet flooring, and industrial plastic waste [2].
"The ECONYL® Regeneration System starts with rescuing waste otherwise polluting the Earth, like fishing nets, fabric scraps, carpet flooring and industrial plastic all over the world. That waste is then sorted and cleaned to recover all of the nylon possible." - ECONYL [1]
Aquafil's U.S. facilities play a big role by processing large amounts of carpet waste, reinforcing the eco-friendly nature of ECONYL [1].
One standout feature of ECONYL is its ability to be recycled endlessly without losing quality. As Aquafil CEO Giulio Bonazzi puts it:
"When I see a landfill, I see a goldmine." [3]
In April 2019, Adidas showcased this material in its Parley swimwear collection, proving that ECONYL performs just as well as traditional nylon in technical applications [4].
Why ECONYL Works for Swimwear
- Ocean Waste Reduction: Transforms discarded fishing nets into something useful.
- High Performance: Matches the properties of virgin nylon.
- Long-Lasting: Can be recycled over and over without breaking down.
- Design Flexibility: Works for both high-performance and luxury swimwear.
ECONYL combines eco-consciousness with top-tier performance, making it an ideal choice for luxury swimwear brands looking to reduce their environmental footprint.
2. REPREVE Recycled Polyester
REPREVE is making waves in luxury swimwear by transforming post-consumer plastic bottles and textile waste into high-performance fiber. This certified material has already recycled over 40 billion plastic bottles, playing a crucial role in reducing waste and protecting the environment [5].
The process starts with collecting plastic bottles from within 31 miles of coastal areas in developing countries. This effort helps prevent plastic from polluting oceans. Unifi, the company behind REPREVE, then processes these materials - along with post-industrial and post-consumer polyester waste - into certified fiber, resin, and yarn [5].
"REPREVE® is a performance fiber and resin, traceably-made from recycled materials and waste sources. Using recycled materials instead of virgin produces fewer carbon emissions and protects natural resources." - REPREVE [6]
To ensure quality and traceability, REPREVE uses its proprietary FiberPrint technology. This system embeds a tracer in the material, allowing verification of its origins through U-TRUST certification [5].
REPREVE tackles pressing environmental issues head-on. With humans consuming around 1.2 million plastic bottles every minute - and only 56% being recycled [6] - this material offers practical solutions:
- Waste Reduction: Helps keep plastic out of oceans.
- Lower Emissions: Reduces carbon output by using recycled materials instead of new ones.
REPREVE is available globally, ensuring consistent quality and accessibility in major textile markets. It matches the performance of traditional polyester while staying eco-friendly, proving that sustainability and durability can go hand in hand.
3. Organic Cotton
Organic cotton is a standout choice among eco-friendly materials, offering a natural fiber with a smaller environmental footprint. Its properties align well with the performance and sustainability demands of high-end swimwear.
Here's why organic cotton matters: Conventional cotton farming consumes a staggering 25% of the world's insecticides and over 10% of its pesticides to produce 20 million tons annually. In contrast, organic cotton avoids synthetic chemicals, resulting in impressive savings - 218 billion liters of water and 288.7 million kilowatts of energy each year. Plus, CO2 emissions drop by 92.5 million kilograms, which is like taking 20,000 passenger cars off the road annually [7]. These benefits are achieved through organic farming methods like composting, crop rotation, and cover cropping, all of which focus on maintaining soil health.
When used in swimwear, organic cotton is often blended with small amounts of stretch materials, such as elastane or lycra, to ensure flexibility and durability. Some brands leading the way in this space include:
| Brand | Material Composition |
|---|---|
| Luz Swimwear | 93% organic cotton, 7% elastane |
| Ambika Boutique | 98% cotton, 2% elastane |
| Hemp Huggers | Organic hemp-cotton blend with 3% lycra |
| Natasha Tonic | Hemp-organic cotton blend with 4% lycra |
For the best results, rinse organic cotton swimwear thoroughly after exposure to chlorinated water to keep it in top condition [8]. Look for certifications like USDA's NOP, OCS, or GOTS to ensure the materials meet organic standards and are produced responsibly [7].
4. Hemp Fabric
Hemp fabric stands out for its strength and minimal impact on the environment, making it a smart choice for luxury swimwear.
Hemp offers significant environmental benefits. It absorbs 9–15 tons of CO₂ per hectare and grows quickly with deep roots, reducing the need for pesticides while protecting soil health [10]. On top of that, hemp is incredibly efficient, producing 250% more fiber than cotton and 600% more than flax on the same amount of land [12]. This high yield makes it a resource-efficient option for fabric production.
Here’s why hemp fabric works well for swimwear:
| Property | Benefit for Swimwear |
|---|---|
| UV Resistance | Naturally protects against sun exposure |
| Breathability | Keeps wearers dry with great moisture-wicking |
| Durability | Stronger than cotton, ensuring long-lasting wear |
| Comfort | Becomes softer over time without losing its shape |
These qualities make hemp fabric highly effective in water-related activities.
"Considered to be one of the most environmentally friendly fabrics, hemp is naturally resistant to pests, requires relatively little water, and grows quickly. Hemp is a 'sister plant,' meaning it replenishes the soil for the crops around it and is ideal for crop rotation. Hemp feels like a new linen, softening with each wash and wear." – Mara Hoffman [12]
Hemp is also efficient in production, with thread counts typically ranging from 200 to 400 per inch [9]. This ensures excellent coverage and durability, perfect for high-end swimwear designs.
To enhance swimwear functionality, hemp is often combined with other eco-friendly fibers. These blends improve stretch and flexibility while maintaining its environmental advantages. Its breathability and moisture-wicking properties make it a go-to material for designers focused on sustainable, stylish swimwear [11].
