"The Traverse 40 has what Exped calls a Switchback frame, that lets you curve the frame of the backpack on demand in order to increase the amount of ventilation between the pack and your back.
Not too far from the Seattle area, where Exped USA makes its home, are the beautiful San Juan Islands. We like to escape to them often, with hiking boots, kayaks, canoes, hammocks and in this case, bikes.
Our Exped sleep system for two people easily fit into the trunk bag of one bike. This gave us a great deal of freedom and saved us a couple times when hotels and hostels were completely full.
