Polyester round slings or lifting slings are versatile for any of the hitch configurations (basket, vertical and choker). Because it doesn’t' have to conform a certain way, the stress points on the sling is distributed throughout the sling and not just one which is the case for nylon slings. The UV resistance make round slings very suitable for outdoor use and unlike nylon slings, polyester slings are unaffected by water. Poly round slings are identified by color and the color indicates the break strength of that particular sling. Poly round slings are sewn seamless only in endless round and eye and eye.
