Russell R.wrote a review of CamelBak FlashFlo Lumbar Pack - 200cu in on May 24, 2012
overall - ok, but mine leaked which is VERY unusual for CamelBak. It's a bit bulky compared to an earlier CamelBak version called the Catalyst. Nice divided storage compartment. The older version had small velcro compartments in the waste band on either side of the buckle which were great for holding energy gels.
