We couldn’t name this rucksack Discoverer and not include lots of details for him to well discover… Let’s start with the best bits first - it’s showerproof and completely packable which means it can be stashed away into its own pocket perfect for rainy trips back from the library or helping carry things home from the market. As for the rest of the bag it has adjustable back straps a main zipped compartment that’s got plenty of room a front popper pocket in which the back packs away into and is adorned in a print we know he’ll love.
