Uphillsport Multilayer socks manufactured in Finland by Sukkamestarit Ltd. We have been manufacturing all our socks in Finland since 1996. We have developed unique, multi-layer socks for all 4 seasons of our inspiring Nordic nature. As we Fins say; there is not cold weather, just inadequate clothing. If your feet get cold or wet, you will not enjoy your outdoor activities. However - when wearing UPHill Sport multi-layer innovative socks you are more likely to enjoy your activities in the great outdoors, with warm, dry feet.
