One thing I have learned to do is to pack ALL my stuff the night before. I use a Camelbak and this is my packing procedure.

Sunscreen, wind breaker and shirt and under shirt in main compartment.
Wallet, Rx glasses(just in case), Contact Lens case(also just in case) in the front compartment.
My bag also has a "Helmet" compartment. I stuff my gloves, computer, light and GoPro in my helmet then stuff the helmet in the compartment.

I hang my chest heart rate monitor strap, my watch and the shirt I am going to wear in the morning on my bike as well.

I clip my keys in the clip that holds the helmet in. All I gotta do is stuff my water bladder in there in the morning as I get ready to head out and I am good to go.

I wake up, take a shower/handle toiletries, put on shorts and the rest is near or on my bike and I am ready to go. Makes the morning SO much easier when I am trying to get two little girls ready and it makes my wife morning a little easier because I am not running around line a banshee trying to get myself ready.

Makes for a nice morning.
