Medium Weight Alpaca / Merino Wool As the flagship of the Dahlgren line, the Light Hiking is the first to feature a brand new and patented network of wicking rings and channels. This new design has been carefully and precisely designed to maximize surface area and substantially improve the rate and quantity of moisture moved away from the foot, keeping you drier and more comfortable than ever. New for this year, the Lt Hiking features a half cushioned foot, providing softness underfoot and a flat knit instep and leg for superior fit and light weight comfort. 
For those familiar with earlier versions of the Light Hiking, this sock is lighter weight, more like the old Ultra Light.
