Thanks for the heads up! So, it seems like there is a need for this at least to a scale I can accommodate.They produced the standard military pattern smocks (in multiple camo patterns), their own SASS Smock, their Kit Karry Smock (upgraded storage), para smock, as well as soldier 95 pattern issue uniforms and would customise/make you basically anything you wanted based on the starting point of one of their existing lines.
Wired hoods, no hoods, lined, unlined, windproof gabardine, standard gabardine, elasticated hidden cuffs, no rank tabs, different pocket layout, extra length etc etc, anything you wanted could generally be accommodated for, effectively a modern continuation for the common (or not so common) soldier tailored clothing.
I've made a few smocks in Ventile and Haley Stevenson waxed cotton, for family and friends. Not as 'fitted' as the modern smocks; mostly copies of the 1942 windproof smock, which is very 'boxy', but I am sure I could copy a modern army one easily.
I guess cotton gabardine and bog-standard polycotton ripstop would be much easier to work with than either of what I've used so far (Ventile can be finicky, and waxed cotton is unforgiving if you need to rip a seam!), so I'd just need to produce patterns for other sizes (I only make them in two sizes for now!) and set up a website!
