In reply to aknight:
Hold the jacket up to a bright light looking from the inside out. If you notice any lighter patches of fabric this could indicate a slight fault in the gore-tex coating. Also check all the seams to see if they have been laminated properly. Be aware it's surprising how wet you can get from condensation and/or water running up your sleeve or down the back of your neck. Any doubts just take it to a shop that stocks berghaus (apart from balcks/millets/etc) and they'll give it a quick once over and let you know how to proceed.
