The RIP SS is the pinnacle of hunting arrow technology, a bone-crushing, small-diameter shaft with stainless steel layers infused into a 90 carbon fiber weave. The RIP SS is lighter and faster than its predecessor, the Xtorsion. With higher FOC and the same sledgehammering momentum, this shaft will punch through anything in its path and will stay straight shot after shot.
