UltraRunning - October 2006
“The Hydrapak is a hydration pack, but actually carries more like a vest. The stiff curved frame features four elevated pads that keep the pack away from the back to provide excellent ventilation. The raised pads take some getting used to, but are very effective. The zippered back pocket has enough room for a light shell and other necessities. The 70-ounce bladder is also unique in its ability to be turned inside out for ease cleaning. An effective push-pull drink valve and a quick connect fitting between the bladder and drink tube are additional features. The Hydrapak is an excellent all-around pack.”
