It's definitely comfortable, but I wouldn't go jog in it (not very supportive).  The removable pads aren't terribly stiff, which is nice.  You want to always remove them for laundering, or they'll turn into bunched up kleenex-like things.  The removable straps have a tendency to go off the hook [whoops!], so you have to make sure you're truly hooked up.  Anyway, at least there's no back hook.
