Reima recommends this classic juniors' backpack with maximum functionality! This kids' backpack is ideal for school kids and students because it comes with a great, ergonomic fit and it is easy to carry even if heavy - the roomy pockets carry all the necessary items, whether school books or other important items. The adjustable and soft shoulder straps together with the chest buckles are supportive and add to the overall user comfort. The padded back panels feel comfortable and do not sweat allowing air to circulate between the back and the backpack. In the main pocket you can find a separate padded pocket designed for a laptop/tablet - this comes with a handy drawstring system that makes it easy to get out the device from the bottom of the pocket. On the bottom of the main pocket there is a removable and reversible bottom structure. Reflecting details - of course! None of the Reima juniors backpacks include PVC.
