Yes or No

If I use a pad under my 0 Degree bag will it help? or is it just extra weight....

I am slowly becoming a gram counter...

I will add warmth, yes. The insulation of your sleeping bag that is underneath you gets compressed between you and the hammock, becoming less effective. You either need to use a pad or better yet an underquilt instead.

and sometimes some of us use a pad AND an underquilt...I did two nights ago in the woods...a pad has lots and lots of uses---comfort in a hammock is not one of them. That said they are super affordable and can act as pack frame,sit pad, and a pad for the ground if the Lords of Cobol dictate you being there.

If the bag is synthetic the pad will help. If the bag is down, IMO the pad will help even more. The more compressible your bag insulation is, the more you need something non-compressible below you.

Still, even with a pad, most folks report being cold before they hit the rating of their SB. This might be true on the ground as well, it depends on the sleeper, on the optimism of the rating, wind... lots of things.

The nice thing about CCF is that it's more bulky than heavy... if you can strap it to the outside of your pack it's really not a big deal to carry except for true gram-weenies (no offense to my SUL brothers and sisters out there!)

I use a section of Wallyworld blue pad, from hip to hip and midthigh to kidney, in between the layer of my Blackbird. This is to help extend the range of my UQ down to the mid 20's.

If the Lords of Cobol dictate..........classic!!!!!!!!!!
