I was just looking around for hydration systems and came across Profile Design's AquaCell. It appears to have 2 chambers (27 / 17 oz) and, unlike the Aerodrink, doesn't involve a sponge. Looks like a good system, but before rushing to judgement, I figured I'd see if anyone had tried it out yet. Even if you haven't, I'd love to hear everyone's thoughts on the redesigned system.<br><br>
