  • What is Extra Life Lycra? What ExtraLife Lycra Swimwear Do We Sell?
    Xtra Life Lycra delivers the properties of Lycra, such as the soft feeling and beautiful fit but also gives swimwear a longer life with less fading and without becoming as baggy. Xtra Life Lycra is resistant to chlorine and pool chemicals 5 - 10 times longer than regular Elastane. This makes Xtra Life Lycra an excellent choice as fitness or training swimwear for male and females. But choose a swimsuit with a high Polyester content and less Lycra, for longer life. We sell Xtra Life Lycra swimwear in both www.acquawear.com (Korean Swimwear and Kneesuits) and www.curvybathers.com (Kneesuits) shops. Our Korean made Kneesuits Jkuss and Tornado are extremely popular, because of the outstanding prints, soft and body hugging fabrics and styles with Lycra content 20%, see individual listings.
  • What is Chlorine Proof Swimwear? Does Acquawear Sell Chlorine Proof Swimwear?
    100% Polyester and PBT swimwear fabrics are by far the most durable and long lasting. Although not as comfortable against the skin as Lycra based fabrics, Polyester/PBT blends are without a doubt the best training swimwear for men and women, due to their incredibly long lifespan. Chlorine proof swimwear has less stretch and thus provides a tighter fit and some people, maybe not as used to regular swim training, might find it constricting and need some time to get used to. The fabrics are less stretchy than Lycra so make sure that you check the size and measurements charts and read the advice of how the suits fit given by the seller, as they most likely have feedback not only from the manufacturer, but also from the customers. Swimsuits made of 100% polyester should retain their colour for at least a year of regular use, but most last much longer and are called chlorine proof for this reason. Chlorine resistant (proof) swimsuits also keep their shape because polyester isn't destroyed by chlorine like nylon or Spandex. Most of the top swimwear brands feature a range of durable PBT or 100% Polyester swimwear, and some brands manufacture exclusively their colourful swimsuits from durable fabrics. All our Delfina custom printed swimwear (except Kneesuits) for women or guys and for clubs are made out of chlorine proof fabrics and are the best choice for maximum swimsuit life and value for money. We stock also Korean brands in small sizes on our Acquawear website (Jkuss, Hoog and TSNine) chlorine proof swimsuits, just look for "T" in the product code and description (Tough, 100% Polyester).
  • What are Sustainable Eco Fabrics? Do we Use Sustainable Eco Fabrics in Our Swimwwear?
    Eco Fabrics - Carvico Xlance Eco For all our Delfina custom made swimwear (for Men and Women) SINCE 2021 (except Kneesuits), we use the Eco fabric Xlance, newly released by the Italian manufacturer Carvico. It is an eco-sustainable fabric designed to promote re-use, recycling and respect for our environment. According to Carvico, the fabric shows extraordinary performance in terms of resistance to chlorine, ensure perfect fit, exceptional comfort and a unique, contemporary and elegant ‘Made in Italy’ style, and they are revolutionizing the worlds of swimwear and sportswear. XLANCE fabrics put together XLANCE unique, high-tech elastomeric fibre and a selection of exceptional and eco-sustainable yarns to meet the requirements of the market and the latest swimwear and sportswear trends, Carvico explains. “Moreover, they are eco-sustainable. Carvico has always operated in the view to safeguarding the environment promoting a more sustainable fashion. XLANCE fabrics stem from a long and thorough research process for fully sustainable raw materials and production processes,” the company says. “XLANCE elastomer is produced without the use of solvents and can be thermoset at lower temperatures compared to fabrics containing standard elastomers thus reducing CO2 emissions and saving relevant amounts of energy.” “XLANCE elastomer is here mixed with several eco-sustainable yarns: ECONYL (used in XLANCE ECO), a 100% regenerated nylon yarn from pre and post-consumer waste materials such as discarded fishing nets, carpet fluff and tulle, and a regenerated polyester yarn from PET bottles (used in XLANCE PLAY).” ​ “XLANCE fabrics ensure a perfect fit and maximum comfort and fits the body like a second skin adapting and shaping its curves and offering athletes support and maximum freedom of movement, Soft and pleasant to the touch, all these fabrics are suitable for printing (sublimation and digital). ”Sport as a lifestyle, wellbeing as a state of mind “XLANCE World by Carvico offers a selection of high-performance fabrics ideal for training and competition swimwear, which can satisfy the needs of every athlete without forgetting about an exclusive 100% made in Italy style and glamour,” the company adds.
  • How is Lycra Used in Swimwear?
    Lycra (also known as Spandex or Elastane) is always mixed with another fibre, usually polyamide (known also as nylon) to give it resilience and stretch. A Lycra swimsuit will generally last less than 2-3 months if exposed to chlorine regularly, it will fade and becomes baggy as the chlorine breaks down the fibres. Lycra swimwear is a choice for leisure swimmers and those who seldom visit the pool, swim in open water or take a dip on holiday. The material is soft against the skin, very comfortable and the prices are generally cheaper.
  • How should my swimwear fit?
    For the best fit, our swimwear made from Xlance Eco fabric should be snug, not baggy. This ensures you achieve the ideal shape in the water. The fabric has excellent stretch, so it will conform to your body comfortably. Make sure your suit is tight enough to provide support but not so tight that it restricts movement. A well-fitted suit enhances your swimming experience and performance.
  • Swimwear Care Advice
    It is so easy to come home tired from the pool, lake, river or beach and just stick the swimsuit in the washing machine, together with the towel, and dry it after on a hot radiator or even stick it in the dryer! But please, DON’T DO IT!!! If you want your suit to last, keep its colours and shape, just DON’T DO IT! Remember to never wash your swimming costume with detergents or in a washing machine. Just give it a good rinse straight after exiting the pool and hang the suit to dry away from a source of heat, and this will ensure the longest possible lifespan for your swimsuit, whatever fabric it's made from. We have a lot of personal experiences in using swimwear, and if you think your suit has become a bit grubby with body oils or the algae from river / lake, just hand-wash it a bit more thoroughly in a basin, with some Fairy Liquid or any dish soap and hang it on a banister. Swimsuits that haven't been properly cared for, as per the manufacturer's label / seller's instructions - swimwear that has been machined washed, put in spinners, centrifuges, dryers will void any warranty.
  • Do you sell my personal details? Do you share them with Third Party?
    The answer is a definite NO. We don't work with any other companies and our website doesn't let Google or any other companies advertise on it. The only personal data we use is for orders' delivery and replying to your questions. We email up to three newsletters / month, but if you don't want to receive them in the future, please unsubscribe at any time.
  • How can I pay for the items? Do I get a refund if I change my mind and return it?
    We take Credit and Debit Cards through our provider, Stripe. We sometimes add Paypal to the checkout, but as their fees are double and non refundable for returns we prefer the Credit Card payments which are as safe as Paypal. Yes, you can return for a product refund (postage will not be refunded) or exchange. We prefer if you can accept an exchange, especially if your return is after the 14 days. If you are in doubt of what size you need, please ask for more advice. If you change your mind, you have to let us know within 14 days.
  • How does the swimwear sizing compare to the ladies UK clothing sizing?
    The swimwear size on our website is the same as the Lingerie and Swimwear Sizing you use when buying a bra. We have measured some of the swimsuits (each individual style and size) and put them in a table for you to compare the measurements to the swimsuit you currently wear. Please see individual product for its own measurements chart. For all Waterpolo swimsuits, bear in mind that they are lined with the same fabric as the swimsuit, so that would make a difference to the fitting, so please allow an extra size up for the extra thickness. Manufacturer's chart with equivalent sizes also available for our eco friendly swim costumes.
  • Can I have a custom print made for myself and how long does it take for a custom print item to arrive? Can I customise the style?
    Any past print can be made for you, but the minimum order is five pieces, so if you get together with friends and family, you can place this very small order together. It takes approximately 3 weeks to receive your custom suits. You can see the styles available on the Clubs page, but it is not possible to change or customise any of the features, except add personalisation.
  • 4. Do you ship internationally?
    Yes—worldwide. To the UK we ship from Northern Ireland, combined DHL (from the factory to us) + Royal Mail (to the UK customer) To EU we ship by DHL, directly from the factory. To elsewhere in the world, it could be a direct delivery from the factory or combined (like above).
  • 3. Plaats uw bestelling
    Het ontwerp wordt nu aangepast aan alle onderdelen die je nodig hebt als onderdeel van je set, maar in de toekomst kunnen er meer onderdelen worden toegevoegd. Je moet ook beslissen of items gepersonaliseerd moeten worden en de plaatsing, grootte en lettertype van de namen of initialen kiezen. Er is een toeslag van £ 2,50 / naam / stuk. Het volledige ontwerp moet worden goedgekeurd en de leden zullen maten en stijlen moeten kiezen. ​ Onze kits zijn van de hoogste kwaliteit en worden vervaardigd in een moderne EU-faciliteit. De stoffen die voor de badkleding worden gebruikt, zijn chloorbestendig en volledig gevoerd met een witte voering (zwarte voering beschikbaar tegen een toeslag van 10%). De heren waterpolo zwemslip is gemaakt van dubbele stof. ​ Over het algemeen zijn de beschikbare maten van maat 20 tot maat 40, maar sommige damesstijlen zijn beschikbaar tot maat 48 (Britse kleding 24 / 26). ​ Nadat de bestelling is geplaatst, sturen we onze factuur die moet worden betaald voordat de bestelling wordt verzonden. Het duurt slechts 3-4 weken om uw bestelling te ontvangen (afhankelijk van het type levering dat nodig is: Express of Economy). ​ Herhaalde bestellingen zijn niet beperkt tot een hoeveelheid, maar als de bestelling kleiner is dan 5 stuks, worden er administratieve kosten van £ 20 aan de eindafrekening toegevoegd. Minimale bestelling voor trainingspakken is te allen tijde 10 stuks, inclusief nabestellingen. Het kan zijn dat het voordeliger is om een grotere herhaalbestelling te plaatsen, aangezien de verzendkosten behoorlijk hoog kunnen zijn. Verzendkosten zijn extra en omvatten extra speciale bezorgkosten van Noord-Ierland naar Groot-Brittannië (indien rechtstreeks vanuit onze EU-fabriek verzonden, moeten klanten douanebelastingen betalen). Houd er rekening mee dat de prijzen die op het moment van bestellen op de website worden vermeld, de prijzen zijn die u voor uw bestelling betaalt. Houd er rekening mee dat prijzen per bestelling kunnen veranderen; bijv. een fabrieksprijsverhoging van 18% vanaf 1 augustus.
  • 2. Kies je Sjablonen / Stijlen
    We hebben een uitgebreide reeks sjablonen die kunnen worden aangepast. We raden je aan om te beginnen met één zwempak en één paar jammers of slips en wanneer het ontwerp is goedgekeurd, zetten we het over naar alle items die je nodig hebt als onderdeel van je kit. Het is de gemakkelijkste en snelste manier! Als u erg kieskeurig bent over de kleurtint, stuur ons dan de Pantone-code of we sturen u het stofkleurmonster. De kleuren van de schermresolutie zijn lichter dan de kleur van de stof, dus we raden u aan de kleuren niet te kiezen zonder het kleurvoorbeeld van de stof te zien. ​ Zodra je het ontwerp hebt goedgekeurd, kun je beginnen met het kiezen van de kitstukken. Uit ervaring hebben we geleerd dat clubleden liever een keuze hebben in welk type pak ze kunnen hebben, aangezien verschillende pakken bij verschillende lichaamstypes passen, dus hoe meer keuze ze hebben, hoe groter de kans dat ze bestellen. Vergeet niet dat in de sjablonen voor clubbadkleding professionele badkleding (FINA-goedgekeurde badkleding) is opgenomen, racepakken die kunnen worden aangepast aan de behoeften van uw club. Trainingspakken kunnen afzonderlijk worden besteld, maar houd er rekening mee dat de minimale bestelling voor trainingspakken te allen tijde 10 stuks is, inclusief nabestellingen. ​ Voor de maatvoering raden we alle clubleden aan om de maattabellen en/of de maattabel voor zwemkleding (indien inbegrepen) te controleren. We hebben een aantal maatsets voor oude vormen, maar voor alle vormen in het gedeelte Sjablonen kunt u de meegeleverde tabellen gebruiken, aangezien de fabrikant geen maatsets meer levert.
  • 1. Clublogo en kleuren
    Stuur ons het logo van uw club in een bestand met hoge resolutie. Wij geven de voorkeur aan vectorbestanden, maar een hoge resolutie .jpeg zou volstaan. Laat ons uw kleuren weten en een kort idee van het ontwerp. Hoe beter je een idee hebt van hoe het ontwerp eruit moet zien, hoe makkelijker het is voor de ontwerper om met iets te komen dat je leuk vindt. Je hebt twee vrije uren ontwerperswerk, wat voldoende zou moeten zijn voor een rechttoe rechtaan ontwerp (daarom raden we een goede briefing aan). ​ Je kunt gratis een gloednieuw ontwerp laten maken* (zie hierboven), zolang je bereid bent om minimaal 20 stuks in dat ontwerp te bestellen.
  • 5. What about returns?
    Custom / Bespoke items cannot be exchanged or refunded (unless faulty).
  • How fast is delivery and can I return if it doesn’t fit?
    We ship quickly across the UK and internationally. If your kneesuit isn’t the right fit, you can return it as long as the swimsuit is unused.
  • What if I’m unsure about sizing?
    Kneesuits usually run smaller. If you’re unsure, we suggest sizing up 1–2 sizes. You can also message us for personalised advice.
  • Are your plus-size kneesuits suitable for competitive swimming?
    Definitely. While they’re stylish enough for leisure, our kneesuits are made with performance fabrics that resist chlorine and salt, hold their shape, and stay comfortable in training or racing lanes. They don't have a FINA stamp, but they compress enough for low level competition events.
  • Do your kneesuits help with body confidence?
    Yes! Many customers tell us they feel more confident because the suits are fully lined, supportive, and don’t ride up. The knee-length cut also provides extra comfort for women who prefer more coverage.
  • What makes a plus-size kneesuit different from a regular swimsuit?
    A kneesuit offers longer leg coverage and a more streamlined fit, ideal for fitness swimming and modesty. Ours are specially designed for curvy and tall body shapes that need extra length and support.
  • How do I choose the right size for thermal tops?
    Our thermal tops are designed to keep you warm both during and after your swim. Made from 100% stretch polyester, they fit snugly while allowing full movement. For the best fit: If wearing under a wetsuit or while swimming → choose a snug fit (go down one or two sizes from your swimsuit size). For post-swim warmth → pick a size close to your swimsuit size for comfort (but avoid going larger). Always check the Measurements Chart on each product page for precise sizing guidance. Many of our thermal tops also come in our signature Owls and Bluetits prints, so you can match them with your favourite swimsuits.
  • Do you offer returns or exchanges?
    Yes. If your order isn’t quite right, you can return it within 14 days in its original condition. We’re always happy to arrange an exchange for a better size or style. Please note postage costs aren’t refunded unless the item is faulty.
  • What types of swim bottoms do you offer and how do they fit?
    We offer three types of swim bottoms to suit different preferences: Unisex swim shorts – Made with our latest Xlance Eco fabric, designed with excellent stretch and durability.

  • How should I care for my swimwear?
    To keep your swimwear looking its best, rinse it in fresh water straight after swimming. Hand wash with a mild soap (no bleach or harsh detergents) and dry flat, away from direct heat or sunlight. Avoid wringing to help preserve the fabric.
  • MAATTABELLEN EN MAATAANBEVELINGEN:
    De waterpolobadpakken gaan tot maat 46. Uit feedback van klanten weten we dat vanwege de volledige ritssluiting en volledige voering de rekbaarheid van de pakken vrij beperkt is, dus we raden aan om minstens één maat groter te nemen, of zelfs twee als je dat bent. ook lang zijn of een lang lichaam hebben. Zie hieronder de tabel met fysieke metingen. Elke stijl werd ongestrekt gemeten: volledige lengte; over de borst (onder de arm); over de heupen (net boven de beenspleet). Hieronder staat de maattabel van de fabrikant voor deze specifieke vorm. Zie hieronder de equivalente maten voor verschillende landen.

  • Reasons For Wearing a Swim Hat
    - To make you more streamlined when swimming, especially for competitive swimmers. A swimming cap should keep your hair out of your face when swimming and will reduce water drag. - To protect your hair from chlorine damage: Especially if you wet your hair before putting your cap on and go in the pool, the caps will prevent your hair from becoming saturated with the chlorinated water. - Hygiene: People who swim without a cap lose hair in the pool which in turn will clog up the filters. - Warmth: If you swim in open water a swimming hat will help to keep you warm in the cold water. You could also double up the caps.
  • Swim Caps Misconceptions
    They are not designed to keep your hair dry! If you read the instructions on our RAS swimming caps, they recommend you wet your hair before putting the cap on! Although some caps will do a good job keeping your hair dry, this is not their scope. If you want to keep your hair dry as much as possible, you can use a silicone cap which gives a tight fit and should keep most of the water out, or wear 2 caps.
  • How should I care for my swimwear?
    Rinse in cool water immediately after swimming, roll in a towel to remove excess water, dry flat away from heat / sunlight, and avoid fabric softeners and machine washing to preserve elasticity and print.
  • Do you ship internationally?
    Yes—worldwide. UK orders ship via Royal Mail; EU customers may prefer DHL to avoid unexpected customs fees. We ship from Northern Ireland.
