I have a few of the other Freezer dresses, such as the straight ones with the ties on the bottom sides.  This dress is a different material than those - this is much more like workout pants or swimsuits, vs the other dress material which is more of a crisp nylon feel.  Both are comfortable, but in my opinion the other fabric is a bit more versatile and dressy - this definitely looks like a swim dress.  Cute, but not something Id wear out or to work with a sweater.  Perfect for around the yard or beach, and flattering on.  It says it is the cooling tech fabric, whereas the other is omnishield (cooling and sun protection).  Oddly, the sizing is different than the other Freezer styles as well.  I wear a small in the other styles (maxi and straight side-tie) but in this a medium fit perfectly.  So if you own the other style, just beware that the sizing is not the same.  Anyway, I wanted to outline the key differences in case anyone was comparing the two styles.  I do like them both, but they are decidedly different materials and looks.
