A garment for boosting circulation in areas of a user's body corresponding to the user's joints, having at least one fabric member of a size for at least partly covering at least one part of the user's body that includes at least one joint area lying over at least one joint of the user, and at least one muscle area lying over at least one muscle of the user, the fabric member being at least one of dimensioned and structured so as not to compress the part of the user's body covered by the fabric member, the fabric member having a heat insulating property at each joint area to be covered and a heat transmitting property at each muscle area to be covered, so that when the garment is worn, each joint area stays warmer than each muscle area to boost circulation in each joint area.

Aspects herein are directed to an apparel layer system configured to provide variable levels of insulation, warming, or air permeability. The apparel layer system comprises a first layer of material and a second layer of material both extending in a first planar direction. A third layer of material is positioned between the first and the second layers of material and is selectively affixed thereto. An adjustment mechanism coupled to the second layer of material can be mechanically manipulated to shift the second layer of material between different positions or states to achieve variable levels of offset between the first and second layers of material in the first planar direction and in a second direction perpendicular to the first planar direction.

Examples of a sleeve for a garment are disclosed. The sleeve comprises an outer panel attached along respective side edges thereof to form an outer sleeve and an inner panel attached along respective side edges thereof to form an inner liner of the sleeve. The inner liner and the outer sleeve are attached at least along respective edges of their respective lower ends forming a hand opening. An elastic band is attached to the inner liner proximate a wrist area of the sleeve and is spaced apart from the outer sleeve. The elastic band is configured to draw the inner liner into contact with and hug a wrist area of the wearer while the outer layer is loosely fitted around the wrist area of the wearer.

The purpose of the present invention is to provide a heat-retaining article exhibiting excellent heat retention. This heat-retaining article (1) is configured so as to be provided with a first sheet (12), a second sheet (13), and a filler material (15) positioned between the first sheet (12) and the second sheet (13), and is characterized by being equipped with a plurality of joining sections (11) for joining the first sheet (12) and the second sheet (13) to one another, and in that the plurality of joining sections (11) are separated from one another and form a dot pattern.

The present invention is directed to thermally-insulated garments and methods of forming the same. The garments in accordance with aspects herein have one or more chambers filled with a thermally-insulating fill material. The thermally-insulating fill material includes a plurality of crimped thermally-reflective polymer strands. Each strand in the plurality of crimped thermally-reflective polymer strands is crimped to provide an increased reflective surface area for heat deflection/reflection, breathability, and movability of the thermally-insulated garment.

Aspects herein provide for a method of manufacturing a vented insulated garment using non-woven polymer sheets and garments produced therefrom. The method generally comprises providing a non-woven polymer sheet having one or more voided portions, positioning the sheet between two textile layers, and bonding the textile layers together at areas corresponding to the voided portions in the non-woven polymer sheet to form a seam. The seam may be optionally perforated.

The present invention relates to breathable, vented, and insulating cold weather garments. More particularly, the present invention relates to garments with chambers to retain an insulating fill material. Perforations along the seams between the insulating chambers may achieve optimal evaporative moisture transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment.

Disclosed herein is a limb sleeve to be worn by a wearer, in accordance with some embodiments. Accordingly, the limb sleeve may include a first opening, a second opening, a first cuff, and a second cuff. Further, the first opening located at a distal end of the limb sleeve. Further, the first opening may be configured for receiving a lower portion of a limb of the wearer. Further, the second opening located at a proximal end of the limb sleeve. Further, the second opening may be configured for receiving an upper portion of the limb. Further, the first cuff disposed adjacent to the first opening. Further, the first cuff may be configured to fasten the limb sleeve to the lower portion. Further, the second cuff disposed adjacent to the second opening. Further, the second cuff may be configured to fasten the limb sleeve to the upper portion.

In one aspect, there is provided a fabric containing gas therein, the fabric comprising a weave between warps and wefts, wherein each warp includes an elongate array of a plurality of individual gas cells, wherein neighboring gas cells are physically coupled to each other via a connection, wherein the connection is monolithic with the gas cells, and each cell contains the gas therein.

An adaptive sheet that includes a first layer defining a first length, the first layer configured to assume a base configuration in response to a first environmental condition and assume a lofted configuration in response to a second environmental condition with the first layer being curled along the first length compared the base configuration. The first fabric layer includes a first material defining a second length and having a first expansion coefficient, and wherein the first material is configured to increasingly change length along the second length in response to the second environmental condition, and a second material defining a third length and having a second expansion coefficient that is different than the first expansion coefficient.
