REI Tarn 18
$40, 1 lb. 3 oz. (one size fits kids age 8 to 12)
Your kid needs a hydration-compatible daypack that’s functional and comfortable, and the Tarn 18 rings all the bells at a good price. It logged numerous days with my family this summer, from the Columbia Gorge to the Tetons, because it fits both my son (recently turned 11) and daughter (age 8). They both loved its look and functionality of a real pack.
