    Feels true to size

    I'm 5'11" 140lbs & bought a size 28-- tight at the beginning but as all suits do, it will stretch over time. This is my first brief that I've purchased & very happy with it. I'm expecting it to last much longer than jammers due to the fact there's less material on your legs. Solid suit!

    comfortable and durable. i wear mine all of the time under my pants/shorts in case i want to go swimming. i sleep in them also. if you want less coverage on the sides, go with the 1 inch solar. i have both and prefer the solar now since it  covers less on the sides. my girlfriend loves both on me and really loves my 1 inch tan lines from the 1 inch solar. swimoutlet has the best prices and shipping was prompt.

    The Speedo Solid Powerflex suit is the best in terms of quality, comfort and style.  I have several and keep adding to my color range.  The fit is perfection.  I remove the drawstring because I don't need it and it adds bulges to the streamlined appearance of the suit.

    Good design. As had been warned by others, fit is a little smaller than with other products.  I ordered a 34 when I normally wear 32.

    I've bought both navy blue and red size 30 versions of this suit and they seem strangely different - the blue suit seems to be made of slightly thinner but more comfortable fabric and fits great whereas the red suit is made of thicker, tighter fabric that seems to "squeeze" a bit more and doesn't feel nearly as comfortable.   Not sure what happened here but I bought the red suit about 4 months before the blue one - ? different manufacturers.

    I find myself wearing the blue suit most of the time - it's comfortable and seems pretty durable with no signs whatsoever of fraying, thinning, splitting, or fading after 3-4 months of use.

    Feels too small

    I like the suit..I usually swim in endurance + fabric, but they don't make a solid red i tried the powerflex fabric..It is fine..i wish the logo was embroidered not a "stick on"...and i go a size up..The fit is very comfy..I feel like a a little fishy in the water.and well of course ...  I  look fantastic   (-.-)

    Initially slightly snug,within a few swims was true to size. Quality and fit are fine, as expected. Basic and functional.
