I’m using two of the bags depending on the length of my journeys. I have the Vibe 25L Backpack when I’m only going for 48 hours. It’s easier to carry light. In the new collection, there’s the bigger Venturesafe EXP 45 which is great for 3-4 days and still works as carry-on luggage. I love the idea of having pockets where you can put your passport and boarding pass so you don’t have to take out all of your gear. Of course, if you lock your zippers you’re safer on a bus or the Metro. For me, it’s also really important to have spots for a reusable water container as well. I love that these bags have that.
