An all-suture anchor for attaching soft tissue to bone while creating an interference fit within a bone hole, and a deployment device for the all-suture anchor. The all-suture anchor includes an anchor body having first and second ends. The second end is folded toward the first end, creating a looped distal end of the anchor body, while the first and second ends of the anchor body form a proximal end. The anchor body is composed of a first material having a first density. A passing filament, of a second (different) density, is woven through the anchor body at passing locations such that a pair of free ends of the passing filament extends from the proximal end of the anchor body. The all-suture anchor additionally includes a binding filament bound axially at the proximal end of the anchor body around the first end and the second end of the anchor body.
