Eclipse Solar Backpack - Camo

Eclipse Solar Backpack - Camo
$179.99

Take your mobile devices off the grid with the new Eclipse Solar Backpack. It is the first in a line of solar bags now made in the USA! This backpack combines the traits of a top quality bag with a new, powerful, thin-film solar module. The backpack features multiple organizer pockets for your smart phones, iPods, and accessories. The rear of the backpack features a separate padded laptop cavity. External side mesh pockets can be used for a water bottle holder or other items for quick access. The pack features a large main cavity for books or extra clothing when traveling. The front zippered accessory pouch includes pen holders, cd holders, and a removable clip for USB memory sticks or keys. The light-weight, flexible, thin-film solar charging module provides up to 4 Watts of power to charge your handheld electronics quickly and efficiently.
