We have seen a bunch of awesome solar backpacks here in the past. WALLY 2 is another one with LED rear light, detachable solar charger, cooling back panel, weather resistance, bottle pockets, travel pouches, and a whole host of convenient features.
WALLY 2 can keep your back cool and your food fresh inside. You can use the solar charger to charge your iPhone 7 in 90 minutes.
