  • 4/6/2015 Speedo Fitness quantum splice

    rating star By Lockett

    I usually wear a 4 but bought a 6-great fit!  I would buy one size larger, speedo usually is small.  Looks great!  Fits great.  Would recommend. Was quick to arrive.

  • 11/20/2013 Speedo Quantum splice one piece with hydro bra

    rating star By Judith L.

    It's a good thing that I like this suit because whoever designs competition suits think that all women swimmers are flat chested.  I've searched all over the net and this is the only one that doesn't look like an old lady suit that has bust support.  The fact that they're sold out except for the pink indicates to me that it's a pretty popular suit and there are other swimmers out there with busts that need the support.  So let Speedo know that the supply is not meeting the demand and make more suits with hydro bras!  Service with Swimoutlet has been great.

  • 6/26/2013 The Perfect Suit

    rating star By Angela C.

    Last year I bought this suit in an 11/12 and it fit perfectly.  This year, I bought a new/replacement suit in an 11/12 and it was too big.  I ended up returning it for a 9/10 and it fits perfectly.  I guess with the redesign, everything was changed.  I love the changes, though!  The removable cups are better, the straps in the back are better and don't squeeze your skin (or back fat).  The suit is lap-swimming ready and is comfortably snug enough to hold everything in place.  I am 5"10", 143lbs and swim approx 10,000 yards per week.  I would highly recommend this suit...just watch the sizing!

  • 3/18/2013 Awesome one piece but ran very small

    rating star By Yvonne

    Im 5feet tall and 110lbs. Got a size 3/4. Had to exchange it for a bigger size. The bottom is smaller than the top. Love the design and the hydro bra though.

  • 4/8/2015 Aqua Fitness for new mom

    rating star By Vertigirl

    Exactly what I needed.  I am a women's size 4/6 in jeans with long torso and new mom chest of 34DD and tried on a 6 at Sports Authority- WAY too small. Could not even pull past hips. 8 is snug and supportive without too much digging in crotch.  Perfect chest support for when I'm in the pool or demonstrating on the deck.  Keeps monster mom nipples conceled, also.  Even w color on sides gives a very boxy appearance, if you are hourglass it will not flatter (if that is a concern).  I wish the fit was more flattering To waist, otherwise would give 5 stars.
    Very comfortable.

  • 6/11/2014 Not for me

    rating star By db91

    This was wide in the crotch and bagged around the chest.   Love the design and color but not the right cut for me. I'm 5"7", 143lbs.

    Last year, I purchased this suit in an 11/12 and it fit perfectly.  This year's redesign did not.  I had to return it for a 9/10 (not that I'm complaining!).  The straps in the back have been changed and I find them to look more appealing than before (no squeezing!).  I'm 5"10", 143 lbs and swim approx 10,000 yards per week.

  • 4/13/2013 A fashionabe suit but not quite what I hoped for in fit

    rating star By JustCallMeFish

    The quality of the suit is wonderful. The color combination and unique design are also a plus. However when it comes to that traditional fit one has long known and loved, it comes up a bit short. Not enough to return the suit mind you, but not one of the top fave suits. The padded bust is not a feature one might ever like or get used to, though its purpose is understandable. The crotch area is too bulky due to the design and cut at an odd leg height for some, which complicates the visual aesthetics.However, the freedom of arm movement this design allows for is a delight, but at the same time it squishes one's back into a bulge, which is a tad embarrassing if you have excess body mass in that area at present time. No doubt that will be less of an issue when the swimming exercise gets one into better shape.
