A sleeping apparatus includes a pad section configured to allow a user to lay on the pad section. The pad section includes padding of a predetermined thickness. The sleeping apparatus includes a blanket section coupled lengthwise to one side of the pad section, and configured to fold onto, and substantially cover at least a portion of the user and the pad section. A pocket is permanently coupled to the pad section. The pocket includes an opening. Other portions of the sleeping apparatus are configured to fold into the pocket and be held in the pocket by friction when the opening of the pocket is in a downward position.

This invention describes a 3-layer insulation material comprising a first fabric layer, a second fabric layer and a third fluted intermediate fabric layer between the first and the second fabric layers, the fluted intermediate fabric layer being attached alternately to the first and the second fabric layer with longitudinal seams forming longitudinal channels for the insulation material having individual insulation material bundle inside each longitudinal channel. Also disclosed are a method and an arrangement for producing the same.

Ventilation device comprising a flexible support having first and second edges delimiting a longitudinal opening and being provided with first and second closing devices arranged to cooperate with one another, the ventilation device comprising at least one elastic spacer member which includes a first tab extending along the first edge and a second tab extending along the second edge, the elastic spacer member being constrained when the closing devices are in the closed position, so that the first and second tabs tend to separate from one another, the length of at least the first tab being less than half the length of the first edge

The present application provides a fabric layer, comprising: an outer layer on which a plurality of first connecting portions are arranged; and, an inner layer on which a plurality of second connecting portions are arranged, wherein the first connecting portions on the outer layer are bonded to the corresponding second connecting portions on the inner layer by dotted sol to form fabric layer connecting portions, so that a chamber is formed by every two adjacent fabric layer connecting portions, the outer layer and the inner layer to accommodate a stuffing. The present application further provides a sleeping bag comprising the fabric layer. With such an arrangement, windproof, waterproof and down-proof effects can be achieved.

A nonwoven fabric has a volume-giving material, in particular fiber balls, down and/or fine feathers, and has a maximum tensile strength, measured according to DIN EN 29 073 at a mass per unit area of 50 g/m.sup.2 in at least one direction, of at least 0.3 N/5 cm, in particular of 0.3 N/5 cm to 100 N/5 cm.

For any given thickness of thermal insulation, the usable lower temperature range of a sleeping bag assembly may be extended by constructing it using an inner lining material that in addition to its normal functions of being flexible and capable of retaining insulating materials, is also capable of functioning as a vapor barrier and a radiation barrier. In addition to the standard sleeping bag design approach of incorporating various insulating materials to reduce heat lost by thermal conductivity, the subject disclosure is directed to methods by which heat loss by radiation and evaporation may also be reduced.

A method for producing a volume nonwoven fabric includes the steps of: (a) providing a nonwoven fabric raw material, containing fiber balls and binder fibers; (b) providing an air-laying device, which has at least two spiked rollers between which a gap is formed; (c) processing the nonwoven fabric raw material in the device in an air-laying method, the nonwoven fabric raw material passing through the gap between the spiked rollers, fibers or fiber bundles being pulled from the fiber balls by the spikes; (d) laying on a laying apparatus; and (e) thermally bonding so as to obtain the volume nonwoven fabric.

A sleeping bag that provides a user a greater amount of room, on demand, within the interior of the sleeping bag by including at least one expandable panel. The expandable panel has an open position and a closed position. In the open position, the panel is expanded providing an increased girth and interior volume to the sleeping bag, compared to when the panel is closed. The expandable panel may have a reduced amount of insulation compared to the rest of the sleeping bag.
