Hey Q,
I think I've mentioned this before, but I LOVE my Aquasphere Seal's. I tried them because they reportedly give a better fit, and I'd have to agree. Initially thought I would reserve them for open water, but they fit so good I used them in the pool every session.
Not hitting the pool much at the moment, but left them in the car on a 40C day (104F), and the rubber seal stretched
. Some people think they look funny in the pool, but I'll be buying another pair soon just for the comfort of not having to adjust them through an entire session.
