Which is warmer/better, the Original Wet Wrap® or
the Wet Wrap® ZIP?

Each is effective. It is often a matter of personal preference whether
to Wrap or ZIP. Here are some of the considerations:

• The Original Wet Wrap® is adjustable giving precise control of fit.
  Its belt closure is slightly more complicated than a zipper. People
  of different sizes can share the same Original Wet Wrap® and the
  Original Wet Wrap® can adjust with one who is personally changing
  in size. Often the best choice for growing children, individuals loosing
  significant weight, and programs seeking to have gear on hand that
  can flexibly fit a variety of individual sizes.
  
• The Wet Wrap® ZIP is custom made for each individual and is pre-
  adjusted to a proper, close fit. Smooth, sleek and easy. Just zip it
  up. The choice of swimmers, aquatic professionals, and aquatic
  enthusiasts who want their own and want the best.
