The Camps Bay ($429): If your dad likes to bring his camera along when he travels, ONA's Camps Bay backpack is a sturdy camera and laptop bag. More suitable for the heavy traveler, the bag is made from waxed canvas to protect your tech inside and has a bunch of interior pockets that you can move and customize. My dad also uses a 17'' laptop (the 13'' and 15'' are too small!) and this bag can accommodate one.
Unit Portables €99.00: This bag is so sexy, if dad doesn't like it, I'll keep it. The Unit 01 bag comes with two smaller pouches, Unit 02 and 03, that can carry your precious small goods like your wallet, phone or keys. If they need to be kept safe, you can attach Unit 02 and 03 to the inside of 01, or on the outside if the bag is already too full. The main unit, 01, is for your computer, and it stows a 13'' or 15'' laptop. You can carry the bag by hand or sling it over your shoulders. The diversity of this bag is just awesome.
Garcia Tote ($161): Hasso's Garcia tote bag is big enough to hold a lot of stuff. Along with a laptop, it's spacious enough for 2 or 3 books or magazines and has pockets for earphones, keys and a USB stick. All the stuff in the bag is wrapped up with a simple leather strap that keeps the bag closed. It's of a really good quality, with a lot of leather pieces, and embodies a classic look.
Heathered Backpack ($129.95): We've always liked Incase's classic backpacks, and this one is a twist on that classic made with heathered material. The material gives the bag a more sophisticated look than their usual vinyl bags, but still has the same design and protection to stow your tech. It's compact and easy to take around for traveling.
Shouldercase (€220): If dad likes to travel light and really just needs a sleek case to slip his computer into, the Shouldercase is as simple and minimal as it gets. (Images: as credited above)
