What GearGuys say: Whenever I look at this bag I am amazed again at how awesome it is. It has some spanking good looks for a piece of wheeled travel luggage but also has the versatility of backpacking when pavement turns to trail. The Doubletrack epitomises the term 'Adventure Travel'. It features a robust wheeled chasis with a super-strength mountain bike styled handle and quality inline skate wheels with bearings and a bombproof pack design where functionality is the top priority. The front flap zips completely open like a suitcase so that you can gain access to all your belongings easily and speedily. There are enough compartments internally to keep your belongings in check. When you need to hoof it, the harness system easily zips out and will have you underway in less than a minute. Security is taken care of with the braided wire top handle which allows you to lock it to whatever is close, ensuring your bag doesn't go walkabout without you and the lockable zips will make sure that there are no wandering hands inside your pack. Finally there is the daypack, every travellers favourite friend. Internally it features a universal sleeve which can accomodate a laptop. It is also hydration friendly so you can pop your bladder inside and have water on the go. When it is time to move your life to the next destination, the daypack easily clips onto your main pack which makes moving a little easier.
