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 & heels, broad block bands & 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 & 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 & 3x warmer than comparable thermal socks!
