Its getting colder and the quilt is still in action. I have used the quilt on every trip for since April. I am going to push it to see how long I can use it this season. No problems yet and it has been cooling down in the mountains. I have put the hammock away for the older months and started using the tyvek/ripstop bivy sack. Its gonna suck if I get caught with it in one of those freak cold snaps, but we will see.
