Soar Running's Advanced Race Vest is an ultra-lightweight race singlet weighing just 46g in size M, cut from a 3D-textured crepe woven fabric with fully bonded seams and an entirely laser-cut construction for minimal weight and maximum comfort. A three-panel build, low arm holes, side splits, and a cutaway back free the stride, while holographic detailing marks it as part of Soar's ProtoLab development line.
