This invention relates to a backpack having enclosed compartments suitable for storing and transporting articles requiring thermally insulated and waterproof protection. The backpack is comprised of two-sections, one of which is a thermally insulated compartment for carrying articles that need to be kept cold or warm. The structure of the apparatus is flexible and formed from a combination of composite material sandwiched between an inner and an outer flexible material. Shoulder or carrying straps and a waist strap are integrally connected to the housing so as to adapt to the wearers shoulders and waist.

A backpack having a plurality of compartments including a thermally insulated for carrying cold articles within a lower end portion of said backpack, which has at least one other compartment located above said thermally insulated compartment, said backpack further comprising; A. A housing, formed of a combination of semi-flexible, waterproof material and composite, insulating material, said composite material bbeing located between layers of said semi-flexible material to define a first wall structure, said housing also formed by said semi-flexible material to define a second wall structure, said thermally insulated compartment being defined by said first wall structure, for preventing thermal conductivity of said cold articles from reaching a wearer of said backpack, while maintaining a desired lower temperature of said articles, said at least one other compartment being defined by said second wall structure; B. Carrying straps which are integrally attached to the front side of said housing, for adjustably adapting said backpack to said wearer; C. A first access opening located at the rear side of said housing, leading into said other compartment, a second access opening, located at the rear side of said housing and leading into said insulated compartment, a sealable panel within said housing and defined by said first wall structure, one edge of said panel being pivotably attached to the rear side of said housing, the remaining edges of said panel being removably attached to the remaining wall structure of said housing so as to be in a horizontal position between said compartments; D. Said sealable panel dividing said thermally insulated compartment and said other compartment whereby each compartment is accessible through its respective first and second access openings and both compartments are accessible through the first opening so as a large single compartment is obtained when said panel is detached from said housing and positioned in an upright position.
