The Tortuga Air Backpack is
The Tortuga Air Backpack is probably one of the best investments I've made. I think the backpack is well made, durable, and thoughtfully designed. The option to expand the size of the backpack with a simple pull of a zipper was a lifesaver. I went on a week-long sojourn across Quebec City to Toronto via Montreal, and was able to fit an astounding amount of clothing. I don't mean to get too personal, but as a man of small stature (I stand at 5'-5" and have a slim build) I thought there would be no way for me to use backpacks as luggage. The size of the backpacks I was recommended were way too large and way too unwieldy to realistically use. The thought of lugging some of these packs through crowded bus terminals, train stations, airports, and city streets in below-freezing weather discouraged me from even trying. Yet, Tortuga came to rescue. Fellow members of the Total Awesomeness of Small (a group I made up like two seconds ago), we have our backpack!
