Existing modelThis full-fledged backpack is comfortable to carry both on the trail or the tarmac. A zip-down flap covers the suspension system, converting the unit into a stylin suitcase / shoulder bag that reduces hang-ups with luggage conveyor belts or doubtful hotel desk clerks. The 18L daypack detaches to accompany you on sidetrips from the base camp or the hostel. It boasts tons of organizer pockets, including slots for your PDA, cellphone, and pens. Slots are trimmed with reflective Scotchlite® strips to help you locate things in low light situations.
