Stay connected to the digital world during long days on the go, or on overnight excursions, with North Face's classic 41-volume Router daypack that’s hooked up for 2013 with a Joey™ T1 power supply to recharge your electronic devices. Wherever your explorations may take you, the lightweight Joey™ will equip you with two-and-a-half full battery charges or several days of partial charges to power your cell phone, MP3 player, tablet, or other USB devices. The rugged water - and crush- resistant lithium polymer battery was specifically designed to perform during outdoor adventures, so you’ll stay powered up and in touch with the rest of your team to coordinate logistics or share action shots. Multiple internal pockets in the front compartment and the removable neoprene tablet sleeve in the large main compartment all connect to the integrated cable system to provide flexible storage options. For the ultimate in versatility, the Joey™ power supply can also be removed and used as an emergency power supply in other packs.
