About the Kalf Summer Socks High The Kalf Summer Sock stays odour-free for longer thanks to the Meryl Skinlife yarn. This incorporates silver micro-particles to keep bacteria at bay for more than 100 washes. Kalf creates stylish high-performance cycling apparel for riders who recognise that the devil is in the detail when it comes to their riding experience. Sometimes we don\\\'t recognise the difference the details make until they are presented to us, and very often there are details that we don\\\'t notice at all until they are taken away. These are the details that contribute to the function, comfort and everyday usability of a garment, and they can be very subtle - right down to the method used to join fabrics to ensure the cut of a jersey is perfect, and remains so wash after wash, or the way a zipper sits when closed. Kalf is all about these small details making a garment that is first out of the drawer every time. Key Features > Form-fitting. > Lightweight. > Exclusively available at TRI UK and Evans Cycles.
