WHAT IS BOILED WOOL?
Mittens made from boiled wool are the warmest and known for being tough, lightweight, and wind resistant. It is like a jacket for your hands! They are shrunk in very hot water and pressed into a flat felt like consistency. This makes it very soft to the touch and not itchy like regular.
These mittens have be washed in hot water, pre-shrunk, and felted, which makes them thicker and dense and really toasty warm.
