  • 3/18/2014 New Jammer

    rating star 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.



  • 9/26/2013 Wish it would have lasted longer.

    rating star By Christin H.

    I bought this for my 10 year old last year when he joined the swim team. It never faded or stretched out BUT, about halfway through the season on the butt seam there was a thin patch and eventually a see through circle about the size of a nickel. I hand washed it out right after he got home, no detergent, and no spin cycle. I wish it would have lasted longer being a Speedo and having paid a little more for it.

  • 9/26/2014 terrible

    rating star By Karen Anderson

    My son is a competitive swimmer and we have used lots of jammers over the years. This jammer fell apart in less than 1 month. I have never had that happen before. It was a waste of money. Don't recommend it.

  • 3/5/2014 Speedo jammer

    rating star By LaureV

    The Speedo brand is always true to size and made of sturdier material than some of the other brands.  The material lasts much longer with regards to fading and stretching, especially when the kids are in the pool so much.

  • 12/9/2013 First Pair

    rating star By Jay H.

    This is my first pair of jammers. They are a bit tight on the lower leg but I have gotten used to that and it may very well be the intended design.

  • 11/7/2013 comfort

    rating star By swimgran

    My Grandson swims 5 nights a week, and Saturday meets, November thru March, these jammers have held up! I have ordered them for the last 3 swim seasons. I measure his waist and order that size, they fit well. The most important quality is their comfort, he is very sensitive to how seams feel. At first I got him a cheaper brand, the seams were somewhat raised, he couldn't stand them.  The seams on these don't bother him, they are very smooth and flat. The secret to keeping them nice is rinsing out in cool water to remove the chlorine right after swimming.

  • 10/2/2013 solid suit for laps; sizing runs small

    rating star By Jonathan R.

    Once or twice a week I swim around 3,000 meters. I've been buying this suit for a few years now. It lasts about a year before needing replacement. Note that you should buy a size bigger than what you normally wear, i.e. if you're a 32 waist, get the 34.  It will still feel snug.

  • 10/2/2013 Great Jammer but take care of it

    rating star By Anthony

    Me jean size is 32x32 so I got the 32 its pretty good but a little loose Which makes it a great practice suit for me. The color has stayed strong for me after wearing it about 2-3 hours a day for 3 weeks just be sure to rinse it out after each wear and do not dry in washer or wash in washer.
    Feels fast and smooth through the water and the look is just amazing. Being a first year swimmer this just seems like the best jammer ever being the 2nd jammer i ever had this is the best and i would buy more pairs of this jammer in the future
    Speedo brand is the best.

  • 7/28/2013 cool and comfortable

    rating star By Mike

    I have been using this for lap swimming 5 days a week for the last month or so, in both an indoor pool at a gym and an outdoor pool that is heavily chlorinated. I haven't noticed any change in the elasticity or color (I always rinse it out right away). Which is great because it's a very cool looking suit.

    The fit is near perfect for me (32 waist), though the leg openings are a little tight on my legs. I seem to notice this more when I'm doing breaststroke or eggbeater kicks, and it's probably better than it being too loose.

  • 7/17/2013 Good in the pool and in the lake

    rating star By Peter W.

    I'm a 30 in everything else, but in these the 32 is the right size. Great, long-lasting. I use them in heavily chlorinated pool - just rinse them after, and they last many, many months even a few seasons. Been my mainstay product for a long time. I swim twice a week - a shorter session in the pool and then 2000m in the lake.

  • 2/14/2013 Good

    rating star 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.



  • 8/3/2011 Good Feel, Kind of Short

    rating star 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.

  • 7/10/2011 Color faded

    rating star By Darryl H.

    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.

  • 4/23/2016 great for awhile

    rating star By Tom

    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.

  • 12/11/2015 Men/Boys

    rating star By amoving

    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 all this and hold up great so I am not replacing them all the time.



  • 11/9/2015 The jammer swim suite fit well and the quality of the suit is outstanding.
