One of the best quality and warmest sweaters you will ever find made by Dachstein in Austria for the Austrian military.Thick boiled wool, oversized collar, ribbed cuffs, 3/4 button front, shoulder epaulets. The Medium Measures 38"-41" Chest. The Large Measures 42"-45" Chest. We believe this is the highest quality sweater in the world! These were issued to the Austrian soldier. They had to return them and now we have them...slightly used. These sweaters are measured by chest and shoulder sizes. They are narrow in the waist to help retain more body heat. Please know that a large will fit the shoulders and chest just as the size should measure but that the waist and midsection is for a slim cut person. It will be tight for a person with a larger midsection. This model has a zipper and is a bit more foregiving around the midsection.
