I'm considering adding this 8-ounce SOL bivvy to my gear, for "as needed" extra warmth, given my late Feb NOBO start on the AT.

My sleep system comprises a 20-degree UGQ Bandit quilt (over-stuffed, wide, long), a CoolMax liner, and a Thermarest NeoAir Xlite. (Tent is a Six Moons Designs Lunar Solo, with a Tyvek ground cover.)

Not sure of how the bivvy, liner, quilt, and pad would all come together. Thinking of using the liner inside the quilt then the bivvy over that combo, with the pad on the underside.

Anyone use this particular SOL bivvy in conjunction with a quilt? Any feedback to share?
