Our backpack is made with durable nylon material and leather details. Two outer side pockets hold your beverages, with one featuring a buckled strap to secure larger bottles (like the Stanley). There is also an outside zippered compartment for your smaller loose objects. Zippered to the bottom of the backpack you will find an insulated lunch box. A laptop compartment (fits up to a 16" laptop) keeps your computer/tablet secure, and an abundance of other pockets and compartments just like you would find in our classic tote.
