Review on Enhance Your Performance with the Profile Design Aero HC System in Clear by Michael Wiley

Love this setup. At Ironman, fill it up at least twice, if not three times. Just flip the lid off as you approach the infirmary, grab a water bottle as you drive by, flip it upside down and squeeze to fill it up in a second or two, flip the empty one aside, leave You flip the lid down again, back in Aero. The position is good to go. I've been using the same bottle for three years, both in training and racing. I thought the top of the latch was worn but it wasn't. I really wish they would only sell the bottle in case it wore out, but for $45 for 3+ years of use I would get another to replace when the loop eventually wore out.
