Abstract
A reversible sweater has a pair of contiguous configurations, one composed of a knit fabric and the other composed of a micro-fiber fabric. A wearer may select which side of the reversible sweater to wear outside and/or inside. If the knit side is worn outside, the sweater (1) has a conventional appearance, but (2) provides warmth which is a function of the knit configuration, and wind resistance, water resistance and vapor permeability, all of which are functions of the micro-fiber configuration. If the micro-fiber configuration is worn outside, (1) the sweater has a fluorescent and retro-reflective appearance, but provides (2) warmth which is a function of the knit configuration, and (3) wind resistance, water resistance and vapor permeability, all of which are functions of the micro-fiber configuration.

Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to clothing and, more particularly, to reversible sweaters that optionally present either customary appearance or enhanced visibility.
Clothing fabrics may be chosen for any of a myriad of objectives, for example: aesthetics provided by patterns, colors, or textures; heat retention provided by natural and/or synthetic yarns of various densities, weaves, knits and/or processing; weather protection, particularly water and/or wind resistance or repellency, provided by coatings and/or laminates; and comfort provided by drape, contour, and/or breathability.
2. The Prior Art
Reversible clothing is constructed from fabrics or combinations of fabrics that may strive to achieve differing objectives. Such objectives may feature opposing textile layers or sides, which merely are intended to present different designs, but which are provided by textiles that are otherwise alike in physical, particularly mechanical, characteristics. In this case, tailoring of the two layers is relatively simple because of their physical compatibility. Such objectives alternatively may feature opposing layers or sides that are intended to provide either (1) customary appearance and function, or (2) enhanced optical and/or weather resistant features. In this case, tailoring of the two layers may be relatively difficult because of substantial differences in physical, particularly, mechanical characteristics.
SUMMARY OF THE INVENTION
The present invention relates to a reversible sweater having a pair of contiguous and interacting textile configurations that combine versatile weather protection with either customary appearance or enhanced visibility. Each configuration includes a full bodice and full sleeves for deployment on the inside or the outside of the sweater, at the option of the wearer. One configuration is a relatively thick, relatively soft knit stratum, which is characterized by conventional appearance, drape, and multidirectional stretch. The other configuration is a relatively thin, relatively stiff micro-fiber stratum, which is impregnated with a fluorescent dye and a weather resistant but moisture permeable composition, and to which is affixed a plurality of retro-reflective bands. The two configurations are free to shift with respect to each other because they are stitched together only at restricted strategic locations, primarily at the collar, cuffs and lower hem. The arrangement is such that, no matter what the reversible option selected, the inner portions of the cuffs, collar and bottom hem are inwardly contiguous with the wearer's body, and the outer portions of the cuffs, collar and bottom hem are outwardly visible to an observer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The Embodiment of FIGS. 1 to 5
The embodiment of FIGS. 1 to 5 is shown as comprising a pair of reversible configurations 20 and 22. As shown in FIGS. 2 and 3, configuration 20 includes a bodice 24 and a pair of sleeves 26, 28, which are stitched to bodice 24 at the shoulders. As shown in FIGS. 4 and 5, configuration 22 includes a bodice 30 and a pair of sleeves 32,34, which are stitched to bodice 30 at the shoulders. The contiguous shoulders of configurations 20 and 22 are free from each other, i.e. are not stitched together.
As shown, configuration 20 is a two layer fabric of conventional appearance having a jersey knit face 36 and a low pile velour back 38. As shown, configuration 22 is a micro-fiber fabric 40 that is impregnated with water repellant and fluorescent finishes 42, and carries a plurality of retro-reflective bands 44. Knit configuration 20 is relatively thick and relatively compliant. Micro-fiber configuration 22 is relatively thin and relatively stiff.
The cuffs of sleeves 26,28 are respectively joined by stitching at 46,48. The necks of bodices 24,30 are joined at a collar 50. The waists of bodices 24,30 are respectively joined at a bottom hem 52.
Woven and micro-fiber configurations 20, 22 are generally coextensive throughout the sweater. The micro-fiber configuration is designed to have added ease, i.e. is fuller than the knit configuration, across the front and back shoulders on the body and around the armhole on the sleeves with two added shoulder pleats (not shown) set in the top seam. The attachment is such as to allow for full freedom of movement when worn over a uniform shirt. Configuration 22 is single needle stitched to configuration 20 at the cuffs, back collar, and bottom hem. There is an access opening at the bottom of the back hem measuring approximately 8 inches long, with a tack stitch at the center which can be opened to allow access to the interstice between the configurations for customization, including the sewing on of emblems. Bands 44 of specified retro-reflective material are sewn around the front and back chest and around the upper arms in such a way as to line up horizontally. Thus, only the critical regions of the inner and outer configurations are joined to each other. The arrangement is such that generally the inner and outer configurations are relatively free to adjust to the body contours and positions of the wearer despite significant differences in their drape and stretch.

OPERATION
In operation, a wearer may select which side of the reversible sweater to wear outside and/or inside. If the knit side is worn outside, the sweater (1) has a conventional appearance, but (2) provides warmth which is a function of the knit configuration, and (3) provides wind resistance, water resistance and vapor permeability, all of which are functions of the micro-fiber configuration. If the micro-fiber configuration is worn outside, (1) the sweater has a fluorescent and retro-reflective appearance, but provides (2) warmth which is a function of the knit configuration, and (3) wind resistance, water resistance and vapor permeability, all of which are functions of the micro-fiber configuration. The knit configuration is relatively thick, relatively soft, and provides multidirectional stretch. The micro-fiber configuration is composed of a relatively rigid material but is relatively thin so as to be reasonably compliant. The two configurations are stitched together primarily at their necks, cuffs and lower hem. The two configurations are slightly different in size so that they are generally free to shift with respect to each other to accommodate different body contours and positions.
