A yoga belt has 2 D-rings stitched one end. The other end is flat with no D-rings or loops. The flat end of the strap is pushed through both D-rings and then back the other way through just the first loop creating a locked loop. This is a similar mechanism to a belt or helmet strap. So which is best for you? A yoga strap can do everything a yoga belt does. But does not lock rigidly into place. A yoga strap enable you to carry your yoga mat and a yoga belt does not. BUT a yoga belt can create a closed loop which is the more common use for this tool in traditional yoga practice. Check them out here: https://mobeco.com.au/product/hemp-yoga-belt/
