Editors 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 Boys' Jammers Swimming Shorts, Black 4.9 5 12 12
Great shorts come up very small My son wanted these shorts for swimming club. I measured his waist and it was 22 " so I ordered the 22". We couldn't even pull these up. After several further tries we ended up keeping the 28". My son is tall and thin so I was surprised we had to size up so much. Now we have shorts that fit they are excellent and most importantly do not slip down when he dives in! I would have given 5 stars if it were not for the sizing issues. 18 April 2014
Great, but watch the sizing I wasn't sure what size to get because these are sized in inches; checked the John Lewis guide and it seems that for my son's age (8) he should be around 24 inches at the waist (which he is); however, when they were received, the jammers were actually size 6 Australian and 112cm European (he is 135cm in height). They are, therefore, VERY snug ... Note to John Lewis ... can you list the other sizes on the label, not just inches, as these don't seem to be particularly accurate in terms of overall sizing and age ... 25 February 2013
Great product Very good quality. Nice fit. My 12 year-old son is very happy with them. 23 September 2012
Excellent swimming trunks These are great trunks. Much better than board shorts. Highly recommended. Great service from Click & Collect. 21 September 2012
Excellent Well made and well fitting just as you would expect from Speedos 27 July 2012
Great value! My son has to wear jammers for his school swimming classes and these were just what I was looking for. They were also much cheaper than anywhere else I had looked (even ordering direct from the school!) 11 June 2012

Good quality swimming trunks/jammers I bought these for my son. They were a perfect fit, good shape and very comfy to wear. Very happy with the product and would recommend them. Very keenly priced I will definitely buy same brand again. 30 May 2012
