Cold weather can't stop you in POLAR SEAL's Heated Zip Tops. Available in four different colours of flexible and breathable fabric, these tops feature two expansive heaters for the upper and lower back, which can be used together or separately. Colour-coded (and water-resistant) LED temperature control buttons on the sleeve make it easy to adjust your Heated Zip Top, with or without gloves on your hands! Clearly, this is a detail-driven design.
