Wet Suits - How to say it is for swimming

Hi all, I was looking at some wetsuits out there, and I am wondering how I can say if they are good for swimming or if they are more for diving/surf/etc...For example, I have seen the following, and I am not sure if any of these will be good for OW swimming: www.swimoutlet.com/.../14109.htm www.swimoutlet.com/.../11895.htm www.swimoutlet.com/.../19378.htm www.swimoutlet.com/.../19357.htm www.swimoutlet.com/.../12257.htm www.swimoutlet.com/.../12258.htm Maybe now a days all wet suits are made for any of these aquatic sports including swimming? If you have any recommendations that will be great. I do not want to spend a lot of money on this. Thanks and regards Bernardo
