Jansport was created in the late ’60s by three avid mountain climbers. Using Mt. Rainier as the testing grounds for their products, they have been on a mission to create the ultimate backpacks. Over the years their backpacks have been adopted by students to help keep their books dry from the rain, thus encouraging the creation of the SuperBreak, a backpack designed for university campuses with students’ needs at the forefront of design. From there on out a whole range of durable and functional backpacks and other outdoor gear has been created by Jansport. If you need any further proof that these products are truly one of the most durable out there, everything comes with a lifetime guarantee from manufacturing defects.
