It doesn't bother me that foreign insignia features on the growbag, but I'm curious as to how the badges are attached.
If not sewn on or attached with velcro, would it be fair to assume that they are metal with some type of clasp to hold them in place? If so, my only observation would be the FOD potential on a dispersal or in an aircraft should a badge or clasp come loose. I'm naiively assuming that the chap is engaged on flying duties - otherwise why would he be wearing a flying suit?
