Editor's Notes

Speedo has a long and impressive history dating back to the early 20th century when the company was created in Australia in response to a growing beach culture down under. Since the birth of the brand, Speedo have always made headlines thanks to the style and the performance of their swimwear.

Speedo dominate competitive swimming with a staggering history in relation to the Olympic Games. Since the 1950s Speedo have had a powerful connection with Olympic athletes, culminating in the Beijing Olympic Games where 92% of all swimming medals were won by athletes wearing Speedo swimwear.

Speedo use the ground-breaking technology they develop for athletes in their commercial ranges to give you a competitive edge and a more enjoyable swimming experience. For example, the Endurance range is developed to be chlorine resistant so you won’t have to replace your swimwear time and again.

Q & As


Speedo Endurance 10 Monogram Muscleback Swimsuit 4.3 5 3 3
Perfect for regular pool users. Good style, fits well, feels comfortable, nice colour (turquoise), and much admired. Fast drying - and reasonably priced. 10 April 2014
Support swimsuit This Speedo swimsuit has extra lining which gives that support that a lot of swimsuits don't have. Very well fitted, though had to get bigger size than normal. Could do with being a bit longer for taller ladies! 12 March 2014
Excellent Swimsuit This is the best swimsuit I have ever bought....and I have tried lots ! Feels comfortably snug...so one less thing to worry about in the water. I'm training for an Ironman...so lots of long distance swims...and I can just put it on and forget about it. No need to constantly pull it up at the front ! Comes up small though ! I am a size 12...but needed the 38". Bought the grey and have now ordered the blue ! 15 February 2014
