Long-Sleeved Polypro Top

You’ve been lied to — merino wool and polyester base layers are NOT warm when wet. Their hydrophilic fibres absorb water and hold it against your body, pulling heat from your core over 25 times faster than if you were dry. That’s a major problem for paddlers, where getting wet is part of the deal. At Canterbury Kayaking, we see the effects all the time: cold, miserable paddlers shivering in the wrong base layer. The Thermadry Polypro Top is different. Made from 100% polypropylene, it’s completely hydrophobic, meaning it repels water instead of absorbing it. Even after a swim, it can trap warm air against your skin and dries almost instantly. Whether you're training for Coast to Coast or paddling in winter, this is the only base layer we trust to keep you warm when it matters most.
