I travel almost every week. One of my 'favourite' things on this planet is the one that I use most. My backpack. It usually carries a 1lt bottle of water, 4 pens, dental floss, 2 laptops & chargers, phone charger, 1 journal, 1 A4 notepad, clean socks. I love using this backpack because I don't have to check it in the airports. I was hoping for a backpack article that would suggest tips, tricks for people like me/us. Travelers with laptops. I was initially disappointed until I started reading. Thank you for this.
