100% nylon. Full press-stud fastening. Camp collar. Chest pockets with flap press-stud closure. Chest pockets with zip. Woven brand patch. Regular fit. This is Nangas Nylon shirt and as its title strongly implies, its concocted from some super strong nylon ripstop fabric which is as breezy as it is long lasting. Theres also one of those camp collars to add yet more casual flavour to the proceedings, and thanks to the semi-transparent nature of that mesh frontage, you wont have to do a frantic self-frisk every two minutes to locate your belongings. That short n stout shape is good too.
