Missing some important info
While everyone is lauding the decision to supply the new pattern material, there is a major problem which has not been noted
Existing uniform material is - in the main - pure woven cotton or cotton gabardine.
The new pattern material is a polyester cotton blend.
In a fire, cotton just chars and turns to carbon. If ti does burn, it burns slowly
Polycotton blends, melt and drip into a very hot sticky burning goo. They effectively glue themselves to the wearer and can cause horrific burns.
I've seen the results of fires in laboratories where the workers were wearing polycotton trousers and overalls, and the results are really not nice - 40% 3rd degree burrs in one case
From what I've been told by an associate who is in the business of making personalised camo gear, the main driver here is cost. The new material is polycotton (immediate cost reduction) made in China (another major cost reduction) and easy to wash/dry
However all that comes with the following problems
Fire risk (as stated above)
Wearability in hot conditions
Static electricity (which can cause havoc with electronics)
Theres also a question of long-tern effectiveness of the waterproofing given the supposed east washability of the new kit
