1) The oft-mentioned "inner workings" of the helmet dissolves rather easily by the "attachment points" in the helmet. The carrier (plastic and adjustable in size (smallest size about 50 o. 2 years)) is pressed from below into four small "U" brackets and not really engaged in this one. Here helps a little hot glue and keeps the thing!
2) In order to increase the comfort for the builder it lends itself to cushion some of the "plastic belt" in the helmet. I have to just something painter Flies (we need the helmet after all on a construction site: o)) cut in strips and this attached with hot glue on plastic carrier. Pay attention to the adjustability of the belt. A fall or slip Duch "cozy but exactly fitting wear" almost impossible "in action".
Would be nice if these "updates" should not be self done. However, they remain within the limits, the "boss" has taken it and approved. Therefore, there are four stars.
