Just wanted to share my experience traveling with a sling bag for the first time, vs my husband’s experience with a backpack.
I carried this bag: G4Free Sling Bag RFID Blocking Sling Backpack Crossbody Chest Bag Daypack for Hiking Travel(Black) https://a.co/d/fmkkFnL
As a side note, I loved this bag: zippered pockets, additional organizers inside, a zippered pocket on the side against your body, side pockets big enough for a plastic water bottle. Didn’t make me to hot because I could change the way I carried it easily.
My husband carried a normal size backpack.
I was able to bring my bag into sites that advertised a requirement to check your bags, including St. Mark’s and the Doge’s Palace. My husband was required to check the backpack at both places.
We were both required to use a locker for our bags at the glass museum in Venice.
