I've got a fleece lined stuff sack that works great as a pillow when turned inside out and spare clothes/jacket stuffed inside.

It might be a good idea to 'trial run' at least your comfort gear with a 'drive around the block' a few times and then camp overnight in your yard. Sure, shower in your house, but only use what you took with you in the first place. Did you lock your bike before you came inside? How was breakfast?

After you evaluate the advise in this thread, one things is for sure, you'll learn from the mistakes 'you' make; after all, that's how the rest of got so smart!

WalksOn2Wheels, what do you think about your sleeping bag? What are the coldest temperatures you have camped with it? I too am working on putting together an ultralight touring setup and need a sleeping bag that can handle nights that will dip down to 30. Here is what I am using for a tent. http://www.cabelas.com/product/Campi...0;cat104303880

I have replaced the stakes with aluminum and will be replacing the poles with aluminum as well to trim weight.

Joe, the sleeping bag did well into the 30's. I, however, did not. (see my next thread)

I am confident that with some layers, this bag would do fine down to freezing temps. I tend to be, I forget how they classify it, a warm sleeper maybe? I like to be really warm. Or at least tired enough to sleep... Again, see other thread.

But the bag did well and performed as expected. I don't think you could climb in it in your undies in 20 degree weather and be perfectly fine, but who does that?

EDIT: I don't feel like I explained the bag well at all. Let me try again.

I was wearing pants, socks, LS wool base layer, LS wool sweater and a wool beanie. This is about normal layering wise for winter sleeping in my opinion. The bag itself into the mid 30's was plenty warm. I had no complaints about the bag. It was even comfortably warm. It could probably do fine down to the 20 degree mark as advertised.

Vapor barrier liners have helped others , keeps moisture in,
so may feel clammy,

But by not evaporating , cooling effect is lower +insulation wont get dampened,
and lose loft.
