GUSTAV SHIRT is a brother of Grym shit (Trekking Pro). The fabric choice, large chest pocket and protective collar made the Grym shirt stand out. We decided to use the same features and design the shirt to make a street friendly version. The standup collar became a two-piece collar but with a button for lifting the collar. The size of the chest pocket was kept large enough for maps but is hidden behind a pleat. I kept the same fantastic fabric and made this style into a favorite on the Asian market.
