Sleek. Strong. Insulated Stainless Steel. The BlenderBottle Radian ® shaker delivers refined style and rock-solid performance. Featuring double-wall vacuum insulation, a center-mounted spout, a detachable carry loop, and BlenderBottle’s most secure seal to date, the revolutionary Radian adds an altogether fresh twist to the shaker cup category.
Double-wall vacuum insulation means shakes stay chilled to the last drop, for up to 24 hours. The stainless steel Radian bottle is extremely durable, resists condensation, and—like all BlenderBottle brand shaker cups—is BPA and phthalate-free.
