wow how cool. I wonder how durable it is though, being non-surplus and all. I bet it would puncture fairly easily if not laid upon a properly cleared & constructed campsite, or maybe the underside has thicker material?
When I do get a bivi I'm 90% sure it will be endicotts upgraded dutch one as 3 layers of goretex sounds pretty damm bombproof, and that is my 1st priority when choosing gear. I heard the poor seamstress is off sick due to back problems, so I'll wait for here to get better. She should visit a skilled chiro!
