The Men's Essential Jammer from Speedo, formerly known as the Fluidfuse Jammer, is in black and white giving a cool look for swim training sessions and fitness swimming. This men's jammer short is ideal for performance swimming with its close fit and has an internal brief and drawstring. The Nylon and Lycra fabric is soft and comfortable and quick drying.
Speedo are a bit expensive but as my son swims several times a week they do last and usually wash well. The sizing seems to suit his tall slim frame.
