Canterbury Thermoreg Baselayer Top Keeping you cool and comfortable in any action, the Thermoreg Baselayer Top comes with thermal insulation. Made from polyester, this is no ordinary fleece lining as Thermoreg technology actually allows more body heat to dissipate and not become trapped within the garment, making it ideal for regulating your body temperature. This baselayer top boosts the evaporation of sweat and in turn has quick drying properties, keeping you feeling cool and dry at all times. Don't worry if you are working out too hard, as the top also features odour control which will enable you to feel fresh. Lastly, the top is equipped with an underarm gusset for added comfort, offset side seams for improved range of motion and engineered fabric for body hold.
