The only thing I've noticed with these polyester jammers is after a long long time they tend to shrink a little. Unlike nylon suits, which wear out quickly, become faded, and lose their elasticity.If you want a practice suit that lasts forever, buy this. I hate people that complain about jammers being "too tight", but with these polyester ones you might consider one size bigger because the shrink over time, at least from my experience owning several of these over the years.I still prefer the nylon jammers because those fit and feel better. They just wear down fast. ### ⭐⭐⭐⭐ The suit is great, but be forewarned *by D***N on Reviewed in the United States on March 13, 2015* The suit is great, but be forewarned, it definitely runs small. I wear a size 28 waist in everything from dress slacks to jeans to bahama shorts. I ordered a 28 in these and couldn't even get them on. After returning them for a replacement I made the mistake of only going up to a 30 for the replacement pair. I can at least get them on, but barely, and they are seriously tight everywhere - in the thighs, the waist, everywhere. They couldn't get any tighter if I sprayed them on. It's too late to return these or I probably would and go up to a 32. Note that despite the sizing issue I would still get these over many others. The build quality is excellent and the material is strong, and if they weren't so tight the fit would be comfortable. Just order a bit larger than you normally would and all will be great. ### ⭐⭐⭐ My son finds Speedo endurance suits work best *by K***N on Reviewed in the United States on May 4, 2013* Udated. While my son uses Speedo endurance, this was mislabled, and it's not an endurance suit; no wonder it was so cheap. It is a Speedo, but wrong fabric and the cloth label doesn't say endurance which they no longer do.My son, who swims year round, has tried various long-life jammers, sometimes just to try them but sometimes because they are chosen as the team suit for the season. He finds that Speedo Endurance fits and performs the best for him. He does wash them himself according to manufacturers label, and I do recommend following that as well. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/1339761-speedo-mens-endurance-mercury-splice-jammer-swimsuit](https://www.desertcart.jp/products/1339761-speedo-mens-endurance-mercury-splice-jammer-swimsuit) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-16*
