Justin B.wrote a review of Ultimate Direction Wasp Hydration Pack on January 31, 2011
This pack is amazing! First time I took it out, I did a 13 miler with no chafing or irritation to shoulders or back. It has tons of storage space for all your essentials; with many pockets right up front for easy access during your all-out efforts. The pack sits pretty high on the back, which is awesome for freedom of movement. Only downsides: don't care for the bladder ( I swapped for a Camelbak 100oz and it fit fine), and the color isn't great ( just a petty complaint!). Overall, I would definately buy again and recommend to anyone.
