Know your fabrics:

  • Endurance+ is Speedo’s most durable fabric, with shape retention and 100% chlorine resistance. Comfortable, quick drying and exclusive to Speedo, it is the premium choice for your swimwear for a soft a stretchy fabric, that will continue to fit like new for longer.
  • Speedo Eco Fabric comes with the added benefit of circular production. Did you know that we source recycled and reclaimed plastic water bottles, break them down and weave them into our Eco Fabric? The result is chlorine resistant, feel good swimwear with a softer hand feel. 

Body Types: Finding The Perfect Swimsuit

Here’s our top tips for feeling confident no matter what your body type. 

If you’re looking for bust support

  • Choose a style with adjustable straps for a better fit and added comfort
  • Thicker straps offer better support for a more comfortable swim 
  • Avoid V Necklines which may be unsupportive when swimming
  • Accentuate your waist with a swimsuit that features a waistband design
  • Don’t be afraid of bold colours or a bold pattern!

Finding your size

Unlike clothing, swimwear needs to sit slimly to avoid drag and gaping when in the water. Whilst our sizing runs true to size according to this slim-fit, you can also use our size charts to find the best fit for you.
