It was plenty toasty just wrapping myself with it outside last night - pretty sure it was in the 20's. Going to lay on the deck tonight with pad and quilt to test total warmth - really no place to hang my hammock at home, and it wouldn't be warm without a finished under quilt anyway. It's going to come in at just over 20 oz with stuff sack, M 50 shell, and 800+ down filling. I wanted it to be plenty warm for that March '13 start. I'm only 5'6", so it's on the short side - 6' total length. I have an insulated Ray-way hat to wear with it for cold weather.
At any rate, pics are here.
If the foot box isn't warm enough as is I'll have a sewing kit on the trail to stitch it shut. I suspect it will be fine, though.
On to the under quilt. . . .
