This travel bag carries your day-to-day cache close to your body so you can maneuver through cobbled streets, crowded fish markets and rush-hour subway commutes with the dexterity of a Parisian taxi driver. The ultralight double-ripstop fabric molds to the shape of your back to stay clear of your arms. The main compartment is roomy enough for a map, lunch and a shell, with extra space for found treasures. One organizational pocket, with a keychain clip, holds easily lost items and a side-mounted mesh pocket holds your water bottle. The 3-point-adjustable mesh shoulder strap has an electronics pocket for your phone or audio device. The entire pack stuffs into its own pocket and the waistbelt tucks into a sleeve. Made of 1.8-oz 40-denier 100% nylon double-ripstop with a polyurethane coating and a silicone finish. Reinforced with 6.3-oz 210-denier 100% nylon double-ripstop that has a polyurethane coating.
