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 (414, 416) and working portion together; wherein the first and second legs (414, 416) define a slot, the slot defining a direction of assembly 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; 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 (414, 416) and working portion together; wherein the first and second legs (414, 416) define a slot, the slot defining a direction of assembly 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; 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.
