The only speedo jammer I have seen that has a matching color drawstring to the design elements! My green primal came with a green cord.
Purchased a pair for lap swimming and workout wear (treadmill to control chafing). Will stretch to fit, size 38 fits actual waist up to 44. If you want a tight fit, order one or two sizes smaller.
I also purchased a blue stripe jammer and found the seams to be bulky around the stripe design pieces, which were also thicker than the rest of the black areas on the suit. This primal model does not have that bulk to the design elements.
