Hey Guest, Early bird pricing on the Summer Moot (29th July - 10th August) available until April 6th, we'd love you to come. PLEASE CLICK HERE to early bird price and get more information.
I don't think you can without destroying the breathable properties
of the Gore-Tex membrane.
Gore-Tex picks up dirt and dust at the best of times which reduce
it's breathable properties (never put a Gore-Tex bivvy bag directly
on muddy ground), so I suspect a dye will likewise contaminate
the micro-porous membrane.

hy,
when you destroy the Gore-tex membrame, whats the effect?
- not waterproof anymore?
- or not breatheble?
If the only effect is that its not breatheble anymore, what's the problem when you lay your bivvybag in the mud...

If it's not breathable, it will be like sleeping in a plastic bag.
Assuming you don't suffocate in your bivvy bag (if it's not
breathable, how can you breathe?), your exhaled breath will form as
condensation on the inside and will have nowhere to go.
Your clothing will be dripping wet come the morning. So, the less
breathable your bivvy bag, the more condensation it will generate on
the inside.
Bivvy bags are made from a slightly different type of Gore-Tex than
clothing. It is more breathable due to the fact that sleeping doesn't
generate much body heat and you need to breathe when you sleep!
As such, it is more prone to contamination than clothing, especially
as it will come into contact with the ground.
Gore-tex is basically a membrane with thousands of tiny holes. Your
sweat is evaporated water (like steam) which can pass through the
holes, but the holes are too big for water droplets. If all the holes become
blocked, your bivvy bag will become the equivalent of a large plastic bag.

Also, this is the reason why you should keep the DWR
up to scratch on your Goretex jacket. If the outer fabric
becomes 'wetted out', the breathablity of the jacket is
hugely reduced. This is because there are less openings
for your sweat to evaporate.
If your jacket no longer 'beads' in the rain,
it is time to reach for Nikwax products.

From my limited knowledge of dying material I know that it is difficult to put a permanent dye in synthetic material.
You have to buy the correct (expensive) dye and then boil the item (which could ruin it of course).
I don't think the dye would affect the gore-tex membrane (I could be wrong on this) as you are dying the outer material which is just a regular synthetic fabric that is bonded to the membrane.
Anyway my reccomendation is "Don't try this at home kids" cos' it most likely will leave you with a washed out looking result that will cost you a lot in dye and might ruin your garment.
