Thanks Herber. Where did you go on your trip? You hit it right on the head when you said "I think I prefer to wear warm clothes to bed and use a light quilt rather than having a separate winter bag. I don't like the bulk of a big bag. This quilt takes up very little space in my bag and does the job if I'm wearing my warm layers to bed". That is what you call a true ultralight sleep system. Layering with clothes you have with you already to complete the "sleep system" is what Super Ultra Light is all about. Multiuse. And it is simplicity! I got to send you another maglite headband now that I angle them down so it makes it more comfortable on the neck to aim the light where you want it.
