If you have noticed the soft feel and firm stretch of a pair of gloves, you have most likely noticed simplex, a fabric used most commonly for vintage gloves. 

Made on a tricot machine, simplex is a firm knit that shows plain stitch knits on both sides, instead of tricot’s zigzag reverse. 
Uses: For gloves, cotton simplex is used after shrinking and sueding. It is heavier than tricot, generally, and appropriate for bottom weight and more tailored items of clothing.
