Thread: New sleeping bag - For hammock.

Any silver coated material works by reflecting radiant heat and looses most of its efficiency if it make contact.
You can easily test this at home by getting a sheet of aluminium foil (kitchen grade) lay it on top of a pack of frozen peas. Now place you hand a few mils above the foil and it feels comfortable then place you hand on the foil and it feels cold.

I suspect the reason P38 finds his setup warm is because he doesn't use it in very cold situations.
I've spent many nights in frost and snow and it works fine but if you never expect to spend a night out in very cold temps P38s idea will work.
Your original question was what sleeping bag?
I would suggest any good quality down bag with a full length zip. If you intend to tramp any distance with it pay attention to its packaged size and weight.
The longest trip I've done with mine is a solo hunt 50km round trip over 7days. in May this year in Fiordland
