    Make sure you measure!!!!  We have some Speedo Jammers and we ordered the same size, but they were at least 2 sizes too small :(

    Bought a pair for my son in his club colors; black and red. The color faded in less than six months. These jammers were a huge disappointment.

    I used the jammers several times a week for about one month. One day recently while putting them on I noticed a "run" in the fabric on my right hip that resulted in a hole.

    4 Review Stars By Rob

    Good Product, Normally wear a size 32 slim fit pant, ordered 32.( my waist is about 31)  Fitted quite tight at first but  after a week or two of swimming fits comfortably. This is meant to fit like second skin, it will be tight. This will show off your "man" parts a little bit, if you are uncomfortable with this maybe go up a size it still should be snug.  Durability and material seems good.

    The Jammer is a great idea. I have 5 boys , all love the water and we wanted a product that could be used not just for swim meets but for all water activities..I found the board liners from Original Watermen to be very versatile.. It seems to be a superior product. We wanted something to stay on in deep water competitions through the waves, surfing, swim meets etc. Original Watermen's board-shorts liners.do all this and hold up great so I am not replacing them all the time.

    5 Review Stars By egold

    After 40 years of Speedos the entire population thanks Speedo for making the Jammer. Seeing a 57 year old in a Speedo is not a pretty sight. The Jammer works just as well and I do not scare little kids and old ladies.

    2 Review Stars By Drinky Crow

    Waist string seems very flimsy, but hasn't failed yet. Leg openings have a too thin seam which acts to constrict your thigh to the point of discomfort. I would not buy these again.

  • 8/3/2011 Good Feel, Kind of Short

    4 Review Stars By Joshua

    I swim 5 times a week, 2 hours a day.  The good thing about the suit is that it feels true to size, and fits well.  The only thing i can find wrong with it is that it is kind of short to my liking, but other than that it is a great suit.
