This pull backpack from JWorld is durable, sturdy wheels, and lots of compartments. I am a Nursing Instructor and I carry lots of books and papers. This is my 2nd JWorld pull backpack. The 1st one lasted 7 years and was pulled on grass and cement, to and from the train station, and even used to pack things while on vacation. I am sure this one will last just as long. Well worth the money!! Very pleased with my purchase.
