Abstract
This is a new method for the construction of waterproof insulated products, by creating individual insulation-filled compartments without stitching through the outer shell of the product. This invention further provides methods for constructing waterproof insulation products without requiring the attachment of the individual compartments to the inner lining.

An insulation product comprising:
- an outer shell;
- an inner liner shell;
- one end of a netting attached to one of the shells to form compartments;
- insulating material added to the resulting compartments formed in the space between the shells;
- the other end of the netting bonded to only the netting of an adjacent compartment to enclose the insulating material and create an air blanket between the compartments and one of the shells.
