Hydration Belt

The next "reward" I'm giving myself will be a hydration belt when I reach 7 miles.  I've been researching these for a while now and I just don't know what I want to get.  I don't think any will be flattering to wear, but I do think it's essential to stay hydrated, and with warm weather approaching I want to be prepared.

  Some I looked at had one bottle that was larger, but when I thought about it, I feel like that was bounce more/be more uncomfortable to wear.  Then I thought about a hand held, but I like having my hands free.








So these are the ones I'm currently looking at:
  NATHAN SWIFT
FUEL BELT REVENGE® R2O 2 BOTTLE BELT
NATHAN SPEED 2


Any suggestions?
