Travel packs need to hold a moderate amount of volume and weight while remaining comfortable as you walk for prolonged periods of time. They also fit in cramped overhead compartments and other small areas, so you can take them on public transportation anywhere. Many have comfortably padded shoulder straps, and some have optional wheels to allow you to literally take a load off when you feel fatigued. Organizational features, such as exterior bungee cords and numerous specialized pockets, help you keep your items orderly when you carry an assortment of things to stay prepared. Unparalleled brands include Timbuk 2, The North Face, Dakine, Osprey, Burton Snowboards, Eagle Creek and Gregory.
