Our wide version of the elastic braces can not only be used as a suspenders for pants but is also suitable for use as a fastener, belt or basic resistance bands for exercising. The specific expandability of this material is the result of the use of a combination of elastic threads in the warp and inelastic polyester yarn in the weft. When you pull on the band, the elastic threads expand up to the point where the polyester weft threads start express their resistance. When the band is subsequently released, the elastic threads constrict whereby the polyester threads return to their original gathered condition. As a means of protection against wear and tear to the warp threads, they are wrapped in polyester yarn before being woven.
