When purchasing the Heatrub Ultimate or the Heatrub Move baselayer please note that due to the fabrics used and the manufacturing process for each garment, the Ultimate comes up slightly smaller than the Move.
Both products are designed for a snug but not overly tight fit, and the stretch properties of the fabrics in the Ultimate and Move allow the user to move freely, whatever their sport or activity.
