I wouldn't say that any one synthetic fabric is superior than a natural fabric material such as Ventile as Ventile Cotton will have lots of excellent attributes, which will be useful in the Wilderness. Same issue with Polyester fleece v Wool.

Ventile had been used for around 70 years now for RAF fighter Aircrew; it still has yet to be replaced with a synthetic.

But if operating in an Environment such as a potentially very wet and windy environment i.e. Scottish Highlands then Goretex/Event/Ceramic Triple Point would probably be preferred material due to its superior attributes of Waterproofness and weight over Ventile.
