Ordered the jammer for diving class.  My 11 year old son is very small and his waist is about 21".   I ordered the 22" (smallest) jammer and it was too small.   We had to re-order 2 sizes bigger.  These run small even though they are compression suits.

I bought this for my 16 year old son to wear for our neighborhood swim team this summer.  Their primary colors are the blue color.  I loved the cool color design, and the way the blue goes around the backside looks great.  I highly recommend this suit.  It looks great on my son, and I think he enjoys wearing it also.

I use this suit for my swimming workout/laps. It fits great and feels good in the water, highly recommended. Colors are bright and clean (I ordered yellow/blue version).

Bought this for my son for his swim team uniform. Fits great and much better than the Club Swim brand of similar style. Fit is very small, so I recommend going up at least one size.

Very happy with them

These are well worth the price.  I had a pair of speedo jammers, which worked, but were extremely uncomfortable.  The Nike jammers fit well, don't itch, and have a quality feel to them.  The waist, which is a little lower than the speedo's, doesn't  show off my muffintops either...bonus!
