Abstract: A respiratory device for covering a head of a wearer can comprise a head engagement element. A hood can define an interior and a rim. The hood can comprise a rim that is configured to bias against the head of the wearer to inhibit air communication therebetween. At least a portion of the hood can be transparent. A hose fitting can be operatively coupled to the hood to provide air therethrough into the interior of the hood. The hood can be configured to be releasably coupled to the head engagement element at a plurality of positions. The plurality of positions can comprise a forward position and a rear position that is spaced from the forward position by at least one inch along an anteroposterior adjustment axis.

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.
