It’s often the ‘twist’ that makes something more interesting, whether it's a twist of lime with your drink or the final twist that turns an entire story on its head. With these men’s Heat Holders With A Twist, the original Thermal Socks get a shake up – same great performance, same great quality – but now with colour twisted yarn! The addition of twisted yarn gives Heat Holders fans a whole spectrum of new options, with contrast toes and heels, broad block bands and mixed rugby stripes. Of course, every pair of our Heat Holders has the same soft thermally efficient inner layer of thickly brushed fibre cushioning that allows them to capture and hold heat like no other socks. Officially tog rated at 2.3, in a pair of Heat Holders, your feet will be over 7x as warm as normal cotton socks and 3x warmer than comparable thermal socks!
