I'm 190cm/6'2'' tall.
The R25 does not have the primary adjustment in the upper harness that some of our other backpacks do, and can therefore sit a little too low to in combination with a waistpack.
If you want to use a waistpack as well as a backpack, I'd recommend the R20. This was designed to be used in this way and therefore is physically shorter and can be adjusted to sit higher on your back.
If you feel you really need 25 liters storage, you could always strap a US-5 onto the R20 to achieve that.
Hope that helps, but do let me know if you'd like any more detail.
