Here’s something amazing – a single brand has recycled more than 1,177,746 plastic bottles into swimwear. These bottles now have a second life as stylish, eco-conscious swimwear instead of polluting our oceans.
My work in sustainability has shown me how green swimwear brands are revolutionizing the industry. The innovations are remarkable. Brands now use recycled fishing nets that provide SPF50 protection and create fabrics from plant-based fibers. Some companies have measured 10,000 women to create the perfect fit while staying true to their eco-friendly standards.
The biggest problem lies in finding genuine sustainable options among countless choices. This detailed guide will help you make smart decisions about your swimwear purchases. You’ll learn about material certifications and fit guidelines that will help you invest in pieces that benefit both you and the planet.
Let’s take a closer look at how you can shop for sustainable swimwear with confidence and make choices that really matter.
Understanding Sustainable Swimwear Materials
“That means that when you buy econyl swimwear, it looks and feels exactly like new fabric would, but without using raw materials like crude oil.” — Not specified, Not specified
The fashion industry has changed dramatically toward green practices, especially when you have swimwear materials [1]. The sort of thing I love is how state-of-the-art eco-friendly fabrics reshape our choices for beach and pool wear.
Common eco-friendly fabric types
ECONYL® is an innovative sustainable fiber made from regenerated nylon waste, including fishing nets, discarded carpets, and industrial plastic [1]. This material matches virgin nylon’s durability and elasticity [1]. REPREVE® turns post-consumer plastic bottles into soft, comfortable swimwear fabrics, and their manufacturing process saves water and energy [1].
Hemp proves to be a remarkable option that needs minimal water and no pesticides to grow [1]. Hemp fabric gives excellent UV protection and natural anti-bacterial properties [1]. It also shows that Vita PL, made from 100% recycled polyester, resists chlorine and sunscreen lotions [2].
Scientists worldwide are perfecting bio-nylon from plant oils in their laboratories [2]. This technology will mark the most important milestone as the first 100% sustainable swimwear fabric once it becomes accessible to more people [2].
How to read fabric labels
Fabric labels are a vital way to identify your swimwear [3]. These labels have used standardized Ginetex graphic symbols through the UNI EN 23758/94 standard since July 1997 [3]. Two main aspects need attention when you analyze labels:
- Manufacturer information: Details about the brand, production location, and fiber percentages
- Care instructions: Specific washing, drying, and ironing guidelines [3]
Labels must list all fiber percentages in decreasing order for compound fabrics [3]. Textile fibers often use abbreviated forms – PL for Polyester, PA for Polyamide, and EA for Elastane [3].
Certifications to look for
OEKO-TEX certification shows fabric safety and sustainability [4]. This certification tests for more than 100 potentially harmful substances such as:
- Heavy metals
- Pesticides
- Carcinogenic dyes
- Phthalates
- Formaldehyde
- Allergenic colorants [4]
The STANDARD 100 label confirms that every component has passed testing for harmful substances [4]. More importantly, MADE IN GREEN certification focuses on environmental and social aspects throughout the supply chain [4].
GOTS (Global Organic Textile Standard) certification ensures fabrics contain at least 70% organic fibers and meet strict environmental standards for organic materials [4]. This certification also guarantees fair working conditions for workers [4].
Evaluating Brand Claims
Recent studies show 59% of fashion companies engage in greenwashing [5]. This makes finding genuine sustainable swimwear brands challenging. The sort of thing I love about being a sustainability expert is helping people spot the difference between real and fake eco-friendly claims.
Key sustainability indicators
Real sustainable swimwear brands share detailed information about their manufacturing processes openly. They’re transparent about worker welfare and fair wage policies [6].
Third-party certifications help verify brand claims. The most respected certifications include:
- OEKO-TEX: Ensures fabrics are free from harmful substances
- Global Organic Textile Standard (GOTS): Certifies organic fibers and fair working conditions
- Cradle to Cradle: Verifies closed-loop production systems [7]
Authentic brands prove their dedication through concrete actions. They:
- Power production with renewable energy
- Save water through smart methods
- Keep factory audits transparent
- Share detailed supply chain reports [8]
Red flags to watch out for
Watch out for environmental claims without specific proof. Words like “eco-friendly” or “natural” often mask greenwashing when there’s no data to back them up [9]. E-commerce sites can be misleading – 40% of their green claims don’t hold up under scrutiny [10].
Here are more warning signs:
- Brands that highlight one green feature while hiding their overall environmental footprint
- Product descriptions missing material percentages
- Suspiciously low prices for sustainable materials
- No information about where and how products are made [11]
Many brands launch “sustainable collections” but keep unsustainable practices in their main lines. This selective approach hides their real environmental effect [9]. True sustainable brands apply eco-friendly principles to everything they make [5].
Packaging and shipping practices tell a lot about a brand’s commitment. Real sustainable brands use compostable or recycled packaging. They plan shipping routes carefully to reduce their carbon footprint [12]. Many offer take-back programs so old swimwear gets recycled properly [1].
Higher prices often signal authentic sustainable products. The cost reflects fair wages, quality materials, and responsible production [2]. The Ellen MacArthur Foundation’s research shows that when clothes last twice as long, industry emissions drop by 44% [2].
Research a brand’s core values before buying. Real sustainable companies care about both environment and people. They set high standards for working conditions and employee benefits [6]. Regular factory audits and worker welfare stories show their integrated approach to sustainability.
Price vs Quality Assessment
“Buy less, choose well, make it last.” — Vivienne Westwood, Fashion designer and sustainability advocate
Smart choices about environmentally responsible swimwear depend on understanding how price relates to quality. My experience as a sustainability expert shows that people often hesitate to pay more without thinking about the long-term value.
Cost per wear calculation
The cost per wear formula reveals the true value of swimwear investments. You can calculate this by dividing the purchase price by how many times you’ll wear the item [13]. To cite an instance, a USD 150 environmentally responsible swimsuit worn 100 times costs USD 1.50 per wear. A USD 20 fast-fashion swimsuit worn only five times costs USD 4 per wear [14].
Quality environmentally responsible swimwear proves its value through:
- Materials that dry quickly and keep their shape
- Protection against sun and chemical damage
- Better durability against daily use [15]
The best environmentally responsible swimwear includes:
- Premium materials like Japanese-sourced yarns
- Ethical manufacturing practices
- Strict quality control standards [15]
Production costs show these quality standards. The manufacturing costs in the United States average USD 65 per swimsuit. Sri Lanka’s costs are USD 3.90 [15]. Of course, this affects retail prices, but the investment pays off through longer-lasting garments.
The right time to invest more
Recent studies show quality now ranks above price as the main factor in swimwear purchases [15]. This change shows people understand sustainability’s role in fashion choices better.
Higher investment makes sense because:
Material Quality: Premium environmentally responsible fabrics provide:
- Better UV protection
- More resistance to chlorine
- Less microplastic shedding [16]
Production Ethics: Higher prices support:
- Fair wages for workers
- Safe working conditions
- Environmental protection measures [15]
Design Longevity: Quality pieces offer:
- Styles that exceed seasonal trends
- Construction that ensures durability
- Versatile designs for many occasions [17]
Low-quality swimwear needs replacement after minimal use. This adds to the 65% of clothing that ends up in landfills within 12 months [18]. So, buying durable environmentally responsible swimwear reduces environmental effects and long-term costs.
The market proves this value. To cite an instance, J.Crew’s premium Italian fabric swimsuits became bestsellers despite higher prices [15]. Environmentally responsible swimwear brands often use materials that cost the same as regular options. The price difference shows ethical production methods [2].
Budget-conscious shoppers can find options too. American Eagle’s Aerie line utilizes economies of scale to offer REPREVE swimsuits at competitive prices while maintaining sustainability standards [19].
Your investment works better if you:
- Pick versatile pieces that match multiple items
- Select classic designs that stay in style
- Check the brand’s quality through customer reviews and material certifications
The higher upfront cost of environmentally responsible swimwear leads to better value over time through durability and fewer replacements [20]. This approach matches environmental responsibility with smart financial decisions.
Finding the Right Fit
Finding the perfect fit is a vital aspect of green swimwear shopping. Leading green brands now offer customized sizing solutions based on measurements from 10,000 women. These solutions will give both comfort and style [12].
Size guide basics
Most green swimwear brands stay consistent with standard swimwear measurements. Your usual underwear size serves as a starting point. Product descriptions mention cup sizes that help achieve optimal fit [21].
For precise measurements:
- Torso: Measure from shoulder over bust, through legs, and up the back
- Bust: Measure around the fullest part
- Waist: Measure around the smallest part
- Hips: Keep measuring tape parallel to floor around fullest part [3]
Fabric types affect sizing choices. Athletes love Foreverever fabric for its minimal stretch, so sizing up makes sense. Recycled Sea-Flex, made from recycled fishing nets, offers more flexibility and fits true to size [3].
Try-on tips
The right try-on practices will give both hygiene and optimal fit assessment. Good hygiene standards matter since swimwear moves between multiple customers [22].
Essential try-on guidelines:
- Wear appropriate undergarments
- Keep hygiene liners intact
- Try swimwear before applying makeup or lotions
- Return items to hangers after trying [22]
Swimwear with straight-across cuts and wide-set straps works best for larger busts. Underwire options with substantial chest bands add extra support [23].
Return policy checks
Green swimwear brands enforce strict return policies to maintain hygiene standards. Return windows usually span 14 to 30 days, based on location [24].
Key return policy considerations:
- Items must remain unworn and unwashed
- Original tags and hygiene liners must stay intact
- Deodorant stains or makeup marks void returns
- Some brands give store credit instead of refunds [25]
Many brands now provide virtual sizing tools and fit consultations to reduce returns and carbon footprint from multiple shipments [24]. These services help customers make smart sizing decisions without ordering multiple pieces.
Some companies extend return windows up to 365 days for store credit, showing their dedication to customer satisfaction [12]. Sale items often remain final sale, so check specific policies carefully [24].
Note that careful handling during try-ons helps future customers and the environment. This approach keeps swimwear in pristine condition, reduces waste, and supports green practices [22].
Care and Maintenance
Taking good care of sustainable swimwear will make it last much longer. My work with eco-friendly fashion has taught me that careful care practices keep garments looking great and help the environment too.
Washing instructions
You should rinse your sustainable swimwear right after using it. Cool water works best to wash away saltwater, chlorine, sunscreen, and other substances that might harm the fabric [4]. The best way to handle your swimsuit is to gently squeeze it into a ball shape. Don’t wring or twist it – that can mess up the fabric’s structure [4].
Hand washing works best for sustainable swimwear. Fill a basin with lukewarm water and pick an eco-friendly detergent made for delicate fabrics [26]. Stay away from harsh chemicals, bleach, and fabric softeners since they can weaken recycled fibers and make colors fade [26].
If you need to use a washing machine, here’s what to do:
- Put your swimwear in a Guppy Friend bag to catch microplastics [16]
- Use cold water to protect synthetic fibers [16]
- Stick to gentle cycles with mild detergent [4]
Vinegar makes a great natural cleaner. Mix ½ dl vinegar with lukewarm water (30°C) and let your swimwear soak for an hour to keep colors bright [27]. This gets rid of smells without leaving any vinegar scent after drying.
Storage tips
The right storage helps sustainable swimwear keep its shape and quality. Make sure your swimwear is completely dry first to stop mold and mildew [26]. Store it somewhere cool and dry, away from sunlight and heat [4].
Temperature matters a lot for storage. Your bedroom closet or drawers work better than attics or garages where temperatures change by a lot [28]. Breathable cotton or mesh bags let air flow and stop colors from bleeding between garments [29].
Here’s what to keep in mind when storing:
- Skip plastic bags – they trap moisture [29]
- Fold everything neatly so wrinkles don’t set in [4]
- Keep swimwear apart from other clothes [28]
- Add natural deodorizers like lavender sachets to keep things fresh [29]
If you own multiple swimsuits, switching between them gives the fabric time to bounce back between uses [30]. This helps each piece last longer and keep its shape better.
Check your stored swimwear now and then for dampness or wear [29]. For long-term storage, think about using special garment bags that control temperature and humidity [29]. These bags protect against environmental damage while letting your swimwear breathe.
Final Assessment
Eco-friendly swimwear marks a vital step toward environmentally conscious fashion that doesn’t compromise style or comfort. Smart material selection, brand verification, and proper sizing help you build a lasting sustainable swimwear collection.
Quality pieces are worth the investment as they last longer and reduce environmental effects. Your sustainable swimwear’s quality and durability improve with proper care like gentle washing and smart storage.
Each sustainable swimwear purchase drives positive change in the fashion industry. Your choices help cut down plastic waste, support ethical manufacturing, and protect the environment.
