I like 1 to 1.5 liters worth of water depending on the time of year and use Nalgene bottles as my standard water bottle for everything.
I really like the BiKase ABC water bottle holder. It has an adjustment knob on the retaining strap that lets you fit larger bottles like Nalgene.
The only downside is any sand or grit that gets between the holder and your Nalgene bottle will grind the hard clear finish off your bottle over time into a dull haze.
