I'm interested in rounding out my novice hammock gear with some essential winter hanging equipment. I don't have unlimited funds (who does?) so i'd like to be wise with what I purchase.

I'd like to hear what you would consider the top 5 most essential items for staying comfortable down to zero degrees F. That includes anything (hammock accessories, clothes, hiking equip., etc.) except for the hammock itself. Don't hesitate to include details like brand and model.

...or you can list your top 5 favorite quotes from Monty Python's Holy Grail...
