For boys, jammers or briefs?
This is largely a matter of personal taste or sometimes team style mandate. Jammers offer compression for the big thigh muscles. Some people find this eases muscle soreness and cramping, but others dislike the feeling of restricted motion. Jammers do hide belly fat somewhat better than briefs. Our experience is that jammers wear out faster than briefs. Jammers have to stretch more and so lose their elasticity faster, resulting in wrinkly and sometimes droopy swimwear.
