I have a homemade quilt with .85 ounce fabric Thru-hiker used to sell. It is now my bag I use when I have to say over-night at work. It has no DWR and any condensation or dew wets out the bag horribly.
My Marmut Pounder is my Adventure Racing bag or for very wet conditions. With a layer of 2.5 ounce Climashield added, it weighs 23 ounces, but has the 15d fabric that is really nice. The new version has the Astral N-100 fabric.
TNF Hightail. Although it's rated for 15* it may be good for 20* but only I eat a few thousand calories before I go to sleep.
My Home-made 2 pound quilt. I'm sure it will keep me warm down to 10*, 5* with some good clothing and 0* with a good meal.
It also weighs less than the TNF bag so if it's going to be blow 40* the quilt goes with me. It's adjustability is a lot better than a bag but the quilt is just too warm above 35*, even when wearing underwear and a t-shirt.
It does works good with a light base layer and your legs outside with the top of the bottom just draped over.
If I was going to go hiking in 0* temps, I could easily push my quilt to -10* with all of my clothing on and my Exped Down mat. Not bad for 2 lbs.
If it is going to be below 35* I will use my prolite 3 short along with 2 GG 60" long 1/8" pads. Other than that it is just a pad or 2. I will never sleep in a camp with hard ground so I have only slept a few nights that my back was stiff the next morning.
Looks like I need to make a 32* quilt though.
I think I'll actually be making a 5 ounce and a 2.5 ounce Climashield quilt since most of the hikes I do have a lot of condensation.
Well, ok, I'll also make a 32* hodded down quilt that will weight about 19 ounces.
