The Hoggs of Fife 100 % Merino Wool Crew Neck Base Layer is perfect for a day in the field on the farm or for your Winter weekend dog walks because it is soft on the skin and naturally antibacterial, helping to avoid odour and reduce washing. Wool will keep you warm, wick away perspiration, and help you regulate your body temperature. It will also help you avoid the post-exercise cold because synthetic base layers cool down quicker.
