Convertible backpack with some great safety features
I use this backpack when travelling on day trips. It recently went with me to Amsterdam. I think its great that it can convert from a backpack to a crossbody bag. Especially as some places (some museums) won't allow backpacks in the building, but they will allow crossbody bags!
I love that you can attach the strap to a pole or chair to prevent the bag from being taken and it's great that it has an RFID pouch to help protect your cards.
The only issues I found were that the straps are quite thin, so they dug into my shoulders when fully packed, and also the Roobar slider was quite loose and easy to open. Possibly too easy if someone knew of the brand and how the Roobar works. I wasn't confident that the Roobar would prevent people from opening the bag, so I also attached a padlock onto the zips for peace of mind.
