Authentic German surplus flecktarn field caps. These have been the standard issue since the mid 1990s, and are very popular and very cool. In recent years, these are becoming more and more difficult to find, along with most other Flecktarn clothing due to the cessation of the Bundeswehr selling surplus.
A couple of notes: Since these are all used, expect wear, fading, and sometimes a tiny tear. You won't be sent a piece of crap, but understand these aren't new.
Also, German hats seem to be sized to be worn very high on the head, because of this, it seems that the sizes are 1/2 to a full size smaller than listed, so if you want a cap that fits lower and not as snug, order a size up from your normal size. If this isn't an issue for you, order your normal size.
