Amongst the categories they address is the luggage that we carry. Outside rightly points out that wheeled carry-on bags sacrifice space in order to give travelers the convenience of those wheels. They recommend the Thule Crossover, a 40L pack that offers plenty of protection for all of your important gear. The Outside editors also recommend that you never leave home without a good pair of noise canceling headphones. In this case, they suggest the Bose QuietComfort 20's, which are small, comfortable, and work extremely well.
Other categories include a small tablet (they give the nod to the iPad Mini), a travel water bottle, comfortable and highly packable underwear from Icebreaker, comfortable travel shoes, compression socks, a neck pillow for use in flight, and a few other items.
All in all, this is not an incredibly comprehensive list, but it does suggest some fantastic items that are great for travelers. A number of these items are things that I carry with me when I'm traveling somewhere, and I'd recommend to others as well. For instance, I can't imagine boarding a long flight these days, and not having my iPad with me. It's just such a versatile piece of gear, allowing you to watch movies, listen to music, play games, read books and magazines, and more. The fact that it doesn't weigh much at all, and has incredible battery life, is just a bonus.
If you're planning any trips in the near future, this looks like a good list of items to choose from to make it a better experience all around. Just like in our outdoor pursuits, the right gear can make all of the difference.
