The Austrian size number is followed by a recommended user's chest circumference. You get a pretty nice fit if you go with your chest size, and you can fit a collared shirt underneath. It is not an ultra-slim hipster fit, nor is it an army tent. Because these come in the "Soldier" cut, the pullover might bulge in the midriff department if your belly circumference is considerably bigger than the chest.

There are no length groups but the smaller sizes are shorter and the larger ones are longer.

Note that some of the garment size tags are faulty. For example, size 4/104 has a tag that says 4/100. The first size number and our suggested user's chest circumference are accurate, and you should stick to them. Sizes 3/100 and 5/108 seem to have the correct tags, all the others have labels where the latter number is 100, probably due to a copy-paste error.

If you are interested in the garment's measurements, take a look at the table below.

Size | Chest width | Back length* | Sleeve length**

3 | 53 cm | 68 cm | 63 cm

4 | 55 cm | 70 cm | 65 cm

5 | 57 cm | 72 cm | 67 cm

6 | 59 cm | 74 cm | 69 cm

7 | 61 cm | 76 cm | 71 cm
