Rupa Jon Men's Cotton Vest (Pack of 5) Tough times don’t last. Tough people do. And they are usually found in a pair of Jon innerwear. That’s because Jon is a good play of quality and affordability. Special stitching is used on 100% fine cotton. The result? Total comfort and total durability. Thoughtfully designed with a double-pouch, and imported rubber elastic (in drawers) Jon is a product par excellence. The Jon range includes Jon vests, Jon drawers, Aishwarya panties, slips and kids’ innerwear (vests, briefs and drawers).
