This whole issue about little sparks from the fire and goretex jackets comes up from time to time here and I think people are over-reacting.
I've seen loads of goretex over the years around many fires -- even some that pop and crackle-- and I've never seen anyone burst into flames or get holes in their jackets.
It's OK. Don't worry.
Goretex has other issues perhaps, but this one isn't a big 'un.
I second this.
I use my Bergans with dermizax (their own "gore-tex) around the fire and it is no problem.
The jacket has got some small holes from sparks over the years though (pine wood fires), but nothing to worry about.
