Also, GripSling is extremely portable and can easily be folded to fit in your pocket, purse, or handbag. These convenient fitness straps are perfect for traveling and your on-the-go lifestyle. Experience GripSling's functionality and take yoga to a new level! Note: each unit ordered contains two straps, and GripSling is constructed with a durable, non-stretchable (inelastic) cotton material.
