Re: Fires. If I'm in a situation where the synthetic fibers are seriously burning ... I've already got much bigger problems. Really.

JACKETS - My own impression is that jackets that have a front zip are a better choice. I find that I am more likely to carry a jacket that can be unzipped ... it is easier to adjust how much body heat is retained - by altering the zip.

I suppose this comment seems 'picky'. But after i put on a jacket then put on a backpack, i like to start trekking and allow my body to fall into a steady natural pace. it is efficient to hike this way. so i adopt the mindset of marching for a very long distance ... and i really dont want to keep stopping frequently, dragging off my backpack, and adjusting my jacket. instead, its much simpler to change the front zipper and so adjust body heat while walking.

cheers,
Pete
