Off to the far east for a few weeks. I always take my rucksack with me when out and about on holiday (money, cards, phone, phone bank, water bottle, sunglasses, snack for DD etc). The problem with a rucksack is that my back gets sweaty!! The advantage of a rucksack is that is distributes weight equally, sounds silly but if I carry a bag on just one shoulder it hurts (I have ongoing issues with shoulder that I've seen a physio about). Any recommendations of what type of bag I could take please.
