I don't have this specific one, mine is one size smaller and pink. I LOVE it
At the top of a hill I'm not reaching for a water bottle but can just pop the valve in my mouth and drink on the downhill without losing my cadence or speed.

I too find I drink way more water with the camelback than just with water bottles. I always take it if I am going more than 25 miles

I have 2 water bottles and cages that I fill as back up, we don't always have some place to stop for water.

I only put water in my CB and energy drink in the WB as I can't imagine cleaning sticky goo out of the tubing

And everyone is right - Ice and water in the CB on a hot day ahhhh
