As it is very hot here now, I thought that I should be taking some water out with me on some runs.
So I got one of these goo.gl/kQ4PzS
It feels quite comfortable with the small bottles nestling into my lower back nicely . It also has a small zipped pouch at the front for a credit card, money, car key, etc.
I carry my smartphone using an old soft spectacles case like this goo.gl/Ft6m1J , clipped to the waistband of my shorts - but I have now found that it clips nicely onto the belt at my side.
PLUS - when I bought it, I somehow got it for half the marked price!!!
