It all begins with your Luggage.
Six years ago i made a great investment in some super lightweight durable luggage from Timberland. These pieces have been around the world and back without any rips, tears or messy spills from my liquids. I never have a problem spotting my luggage at baggage claim because the Timberland colorway is so unique. I typically pack all jeans/shorts/shirts/shoes in the duffel bag along with all my liquids in compliance with TSA. My backpack i use as a carry on for my underwear, laptop, camera and various other electronics. Because the backpack is so bulking i always pack a smaller Jansport bag for day to day use while out and about.
