I'm looking for a rolltop rucksack / back pack type bag, to use at a festival and then a holiday lm going on this year. I don't want it too small or too big, big enough to fit under plane seat but l don't expect to fit all my clothes in etc. More purse, sunglasses, water bottle, suntan lotion, tissues etc. As ever, l have champagne tastes and a lemonade budget e.g. Stubble & Co https://www.stubbleandco.com/products/the-roll-top-20l?variant=40445040165050&gadsource=1&gbraid=0AAAAABWPiw-TDAecviiyJiJqu8h25aVdv&gclid=CjwKCAjwktOOBhBrEiwAV70jXvsMw8GhFLLVcbuTLjJOx5GpGy9EAK-EJK1RnOo4OX1w5T1K7C7bBoCYR4QAvD_BwE but don't have £120! More than happy to go on Vinted or eBay, l have tried searching but only seem to find quite small ones
