Our wool interlock is a blend of 95% Merino wool and 5% Spandex.  It is soft to the touch and breathable.  This wool is certified lead-free and is constructed of Oeko-Tex Standard 100 certified wool blend yarn.

Wool is naturally anti-microbial, is a sustainable fiber, and is considered hypoallergenic, as it resists both dust mites and mildew.  Wool allows moisture to be absorbed and evaporated quite efficiently, and thereby effectively moderates both temperature and humidity.  Wool can be used in hot, warm, cool, and cold weather conditions!
