US Patent 11744303 Endless neck tie and mobius bow tie

An endless neck tie. In one embodiment an endless loop of fabric of varying width includes a relatively narrow segment providing a neckband, and a first blade and a second blade of variable width extending in opposite directions along the loop and away from the neckband. At least a first transition region, between the blades or between the neck band and the blades, is of such narrow width relative to the blade width that the transition region accepts at least a first knot which defines a constricted region of the endless neck tie between the neck band and the blades.
