Man, these are maybe the comfiest sweaters I have worn. They are made of 50% wool and 50% polyacrylonitrile, making them warm, cozy, and not itchy. 

These will come with one breast pocket with a Velcro closure, two shoulder boards, reinforced elbows and shoulders, and most will come with a Czech flag. 

The sweaters come in a few different sizes to accommodate your chest size as well as your height. The sizing is in centimeters for both height and chest size. 
The model in the photos is about 177cm (5'8") in height and about a chest size of about 96cm (38in) and is wearing a sweater for a height of 170cm and a chest size of 96-100cm, and it fits perfectly. 

These are like new but still may show signs of storage wear and may have small tears, small holes, fraying, and/or missing a flag. Otherwise, these are ready to be worn out of the box.
