I recently popped out for a dog walk, which ended up being longer than expected because it was so lovely. However, I'd left the house in leggings and a t-shirt so no pockets - I'd tied poo bags to the lead handle, shoved my phone in my bra and carried my keys. It was not ideal so I've started thinking about getting a little bag/bum bag with essentials in, for those kind of walks in the summer when I am not wearing a coat/pockets.
I just caught myself eyeing up swiss army knives and think I may have gone too far 
Bring me back into line. What would you take for a 1-2 hour walk, on a not-too-hot day, for a walk in the countryside?
