I originally purchased the ExOfficio Give-N-Go Bikini style, but found that the low-rise style tended to bind at the waist and legs, making them uncomfortable for me.  Then, I found these ExOfficio Women's Give and Go Lacy Bikinis and they fit perfectly.  I believe that's because this style seems to fit more like a mid-rise bikini than the other style.  These bikinis are comfortable and I can move and bend all day without any problems.  I also like that these bikinis wash and dry quickly.  Great for travel, but great for every day as well!
