It's time for him to start pulling his weight on the trail--at least a little bit--so after you get him a proper sized backpack, make sure he's got his Merrell Boy's Moab FST Mid A/C Waterproof Hiking Boots on his feet. These tough boots are ready to stomp through muddy Cascade trails or up towering 14ers in Colorado. The waterproof bootie keeps his feet dry when the sky starts to pour and the rubber outsole holds solid traction on scree fields and river crossings.
