Our popular jammer, now with better eco-credentials. We've given our popular men’s jammer an update using our super-durable new ECO Endurance+ fabric. Retaining the streamlined cut, integral support and drawstring waist that make it so comfy during training, it’s now made from 50% recycled materials. Quick to dry and 100% chlorine resistant, it’s ideal for regular training sessions. Review: Exceptionally durable and long lasting - Speedo Eco Endurance jammers are very high quality swimming trunks. They are true to size, and what I would describe as an athletic fit. The fabric is very resistant to chlorine. I swim 3x a week, and rinse the trunks in cold water after every session, as such a pair of trunks usually lasts at least 12 months, often much longer. So the trunks are exceptionally good value. The fabric is slightly stretchy to give a snug fit in the water, and doesn’t go baggy. Over the years I have tried many different trunks and have now settled with Speedos as they are very durable, good value for money, fit me well, and enable me to simply get on with my swimming. Review: Nice jammers - Looks good, fits well and is reasonably priced. The snug fit produces less drag than the regular swimming shorts I used to wear.

Quality
I'm really pleased with them. The quality is excellent – they feel durable, well-made, and perfect for swimming. That said, I did find the sizing a little on the snug side. I measured my waist recently and I’m a 35", so I thought going for a 36 would give me a bit of breathing room. However, the fit is still quite tight – not unwearable, but definitely more fitted than expected. If you're between sizes like me, you might consider going one size up for a more comfortable fit, especially if you’re planning to wear them for extended periods. All in all, a solid pair of swim shorts – just be aware of the fit when ordering.

32 are a bit small
I always wear 32" trousers and shorts, including skinny jeans, so I thought I'd be best sticking with my usual size. Unfortunately for me I found these 32" Speedo jammers a little on the tight size and didn't exactly leave much too the imagination. I know that swimming trunks/jammers are intended to be a tight fit to aid speed while swimming, however comfort is still nessesary both in the physical and styling and I wouldn't be comfortable walking around with so much on show. The quality of these shorts felt very good and the drawstring was a good size. At the time of purchase these shorts represent excellent value for money at £11.50. Unfortunately I will be returning for the next size up (34") which are a little dearer but still excellent value.
