Condition: These are issued/used items. However, they are in, mostly, great condition. You may receive something close to new, but please expect some signs of wear - thinning, and in only one or two, a small repair that you'd hardly notice. Small repairs like this shown in the pictures. For large repairs, still barely perceivable, there are separate pictures for each individual item.
As regards the sizes, these are the original Swiss sizes on the labels. If you would like to convert these centimeter waists and inseams to inches, you can use an online converter (or simply google, which has an online converter)
