Great Place in Your Kit
These have their important place in my kit, for foggy/misty and cool rides . . . something a little extra to keep my socks and calves a bit dryer and warmer . . . that are light and small to stow when the air and roads dry and warm. Think knee sun sleeves/warmers for your calves and ankles. Worth the very small weight, volume, and price for a very great result.
