I use these for lap swimming, triathlon training in open water, and also in the more international tourist-friendly water parks (that aren''t filled with rednecks) and they function well in all cases.  Like all swimwear, they don''t last forever, but for the price, I believe they are among the best deals.

This is a great suit for a bigger guy.  Good coverage in the rear and not too skimpy.  I wear these under my board shorts.

I typically wear size 34-36 pants, shorts, etc.  Brief-style swim suits all seem a little small, so I ordered size 38.  It fits fine.  Fabric is heavier (more durable?) than Speedo suits that I have used.

I have worn mostly the Speedo Axcel and a brief from Sporti. Changing to the Dolphin was a good choice. Comfortable and nice looking. I am a 31 waist and bought the 32 and it fits perfect.

It performs well for me, someone who doesn't swim very much.

I JUST STARTED SWIMMING AGAIN FOR EXERCISE  AND DIDN'T WANT TO USE THE BAGGIES SO THIS SUIT IS GREAT. I DID SIZE UP ONE SIZE ON MY SECOND ORDER... 34 WASTE, I ORDERED A 36 SUIT; I'M NOT BUILT LIKE MIKE PHELPS AND DIDN'T NEED A REAL TIGHT SUIT TO SHAVE OFF ONE ONEHUNDREDTH OF A SECOND FROM MY TIME. RETURNING THE FIRST ONE WAS A SNAP.  I WILL ORDER A FEW MORE OF THESE.NOW THAT THE SIZE IS RIGHT. THIS IS A GREAT COMPANY TO DEAL WITH
