The disclosure provides a sling including a sleeve, a first eye formed by a first splice, and a second eye formed by a second splice. The sleeve includes braided strands and has a first end portion, a second end portion, and an intermediate portion between. The sleeve also defines a hollow inner volume. The first splice is made by the first end portion extending into and along part of the hollow inner volume proximate the first eye. The second splice is made by the second end portion extending into and along part of the hollow inner volume proximate the second eye. A hollow load bearing portion is defined in the intermediate portion between the first splice and the second splice.
