The 20L BackpackThe Naked Backpack is a multi functional bag with a hidden hockey stick holder. It has been constructed from sturdy, durable waterproof fabric with waterproof zips. We ergonomically designed the backpack to include a large central storage compartment, an integrated padded laptop sleeve and small mesh internal pockets to safely store accessories. For extra storage, there is an additional compartment in the front and a side water bottle holder.
