A shroud configured to be attached to a work implement , the shroud comprising: a body defining a closed end and an open end , a first side surface and a second side surface ; a working portion disposed proximate the closed end ; a first leg extending rearward from the working portion to the open end ; a second leg extending rearward from the working portion to the open end ; and a throat portion that connects the legs and working portion together ; wherein the first and second legs define a slot , the slot defining a direction of assembly (A) onto a work implement and the body defines a Cartesian coordinate system having a X-axis, a Y-axis and a Z-axis and defining a X-Y plane, a X-Z plane, and a Y-Z plane, wherein the X-axis is parallel with the direction of assembly (A); and the working portion defines a ground engaging surface at the closed end comprising a convex arcuate portion intersecting with the X-axis, a first concave arcuate portion extending from the convex arcuate portion toward the first side surface , and a second concave arcuate portion extending from the convex arcuate portion toward the second side surface when the ground engaging surface is projected onto a X-Y plane along the Z-axis, wherein the working portion defines an upper outside loading surface extending from the ground engaging surface toward the open end and the first leg , the upper outside loading surface comprising a first concave arcuate loading portion extending from the ground engaging surface toward the first leg , a first convex arcuate loading portion extending from the first concave arcuate loading portion toward the first leg , and a second convex arcuate loading portion extending from the first convex arcuate loading portion toward the first leg . a body defining a closed end and an open end , a first side surface and a second side surface ; a working portion disposed proximate the closed end ; a first leg extending rearward from the working portion to the open end ; a second leg extending rearward from the working portion to the open end ; and a throat portion that connects the legs and working portion together ; wherein the first and second legs define a slot , the slot defining a direction of assembly (A) onto a work implement and the body defines a Cartesian coordinate system having a X-axis, a Y-axis and a Z-axis and defining a X-Y plane, a X-Z plane, and a Y-Z plane, wherein the X-axis is parallel with the direction of assembly (A); and the working portion defines a ground engaging surface at the closed end comprising a convex arcuate portion intersecting with the X-axis, a first concave arcuate portion extending from the convex arcuate portion toward the first side surface , and a second concave arcuate portion extending from the convex arcuate portion toward the second side surface when the ground engaging surface is projected onto a X-Y plane along the Z-axis, wherein the working portion defines an upper outside loading surface extending from the ground engaging surface toward the open end and the first leg , the upper outside loading surface comprising a first concave arcuate loading portion extending from the ground engaging surface toward the first leg , a first convex arcuate loading portion extending from the first concave arcuate loading portion toward the first leg , and a second convex arcuate loading portion extending from the first convex arcuate loading portion toward the first leg . <EOS>
