Goretex is a very fragile mebrame, normally guaranteed for thee years (how long does cotton or polycotton lasT?)
Goretex smock liners can be bought for £15 or so, so a seperate smock/liner combo makes more sense.
My personal choice is a single layer ventile, with good features, and a liner, this gives year round performance, in all conditions, and is good when working around fires (no manufacturers produce kit for bushcraft).
Under garments should be chosen well no matter what the outer, this is the comfort layer as it is next to the skin, merino wool, silk & meraklon are all good choices.
There are environments where trying to stay dry is pointless, instead you stay comfortable (the ethos behind Buffalo Gear),a good natural alternative is a ventile/wool combination, certainly when living with others in a confined area like at tent, BO can become a "grating" point and natural fibres win hands down in this scenario.
