Purchased this bag for a 10-day tour around Italy. I don’t like wearing backpacks but I wanted a secure (and good-sized) crossbody that didn’t look too ‘functional’ so I could use it in the evenings too - this absolutely fit the bill. Plenty of room (I debated the smaller version but so glad I opted for this one). Could easily fit sunglasses, sunscreen (full size), phone, passports, extra shirt, hat, chargers, medicine, and make up essentials with spare room. Also fits a 250ml metal reusable water bottle in the side pocket easily (could possibly have fitted a 500ml) in there too but I didn’t want to make it too heavy and on our trip there were plenty of opportunities to refill). Security features are excellent - I thought it would be a pain to access things but after a day or two remembering which pocket was which it was absolutely fine. I only used the locking features on crowded trains when as I felt the front pocket/flap was secure enough/deterrent enough for pickpockets for walking around day-to-day. Comfortable to carry, and my other half was more than happy to carry it too as it’s pretty gender neutral in appearance. Would highly recommend.
