Following with our web-sling design, the Tri-Sling offers the same superior strength and quality as our other designs. The Tri-Sling has three suspension points while our other web-sling has four. The "V" shape wedge gives maximum access to the butt and the sling is comfortable whether or not you use the included leg stirrups. The "V" shape also creates a bucket-style seat and provides even weight distribution to all support straps. Strong, durable and unique - the Tri-Sling is an Antonio design.
