This is an excellent product for people like me who do open water swimming and want the confidence to be able to get through a cramp or a jelly fish sting and still have flotation. I did a 25 minute the first time and a 45 minute swim the second time, the one big issue i noticed is that you may have to wear a neck gaiter because it rubbed my neck raw in one area, i had to use a gaiter when swimming with an inflatable life preserver, looks like i will have to do the same with this. The other issue is that i wish there were a summer-weight version of this suit because swimming in the summer in Florida is already like swimming in a bathtub so you want to retain as little body heat as possible. In fact cool/cold water swimming is extremely healthy in doses, but this weight of wetsuit will be extremely hot in the summer. I intend on swimming across the Hudson River in it in August, but this time for a longer distance, hopefully i can get through a tryout the Navy SEALs have to swim across with them, fingers crossed :)All that said, this is an excellent product that works as advertised and keeps you floating and in a great posture for swimming, particularly if you're 53 year old guy like me :) I look forward to what Airtime Watertime comes up with in the future :)
