I need a large bag for work and everyday use, need to fit A4 file, iPad etc for work, and wipes, water bottle, sun cream,the odd snack when on a day out with dc.I suffer from shoulder pain but have tried rucksacks, cross body bags and can’t get on with them. It needs to be fairly durable and not too expensive, £125 max. I’ve just come back from a day out and my shoulder is aching so much from uncomfortable shoulder straps, I didn’t even take much out today.
