Rated 1 out of 5 by from Useless for Running I used this for the first time yesterday. The concept of having the bladder on the lower back / waist is great and the reason I bought it. UNFORTUNATELY, the belt does not stay tight. I was having to constantly (every 1/4 - 1/2 mile!) tighten it to keep it from sliding down. It may be good for walking or cycling but definitely NOT for running with current belt.

How does this product differ from the other one currently on sale -- named the "Camelback Flash Flo Hydration Pack"? Is this an opportunity to pre-order an updated version of the pack? If so, have they fixed the waist belt and bladder issues?

This features the new Camelbak Crux reservoir which delivers more water per sip than the old model and has an updated shutoff valve.

How much room is in this waistpack for items like snacks, phone, key, etc? 

Asked by: Heatherlmbt
This waistpack has a gear capacity of 3.5 liters. It does provide plenty of space for your phone, snacks, and keys.
