Speedo Men's Relaunch Splice Jammer Swimsuit

My son loved these at first. They were his favorite pair of the four jammers we purchased in one order. They fit snugly, but not too tightly. Great support. However, the fabric quickly deteriorated, despite rinsing them out after every wear with fresh water and a once a month treatment with a suit saver powder sold by Swim Outlet. Within 5 months of once-weekly wear (rotating jammers so none had excessive use), the rear is almost see through from the spandex breaking down. I expected more than 20 uses before looking for a replacement. I expected better durability from Speedo.
