I am currently thru hiking the AT. I need to switch out my 20 degree bag for the summer.
I am sleeping under a tarp. I am a pretty warm sleeper, usually not zipping up my bag, while my girlfriend has 2 pairs of Capilene 2 thermal pants and her Montbell jacket on, and is zipped up.
I am looking at two options: The Sea To Summit Reactor Thermolite Mummy Bag Liner, which is 8.1 oz,

or BPL's UL 60 Quilt or UL 90 Quilt (the 90 because the AT has been so wet so far).

I obviously want as light as possible. I was thinking the liner since my thermal pants are Capilene 2 and supposedly it will be cold up north in Sep/early Oct (colder than April in Georgia?), so I can add the liner to my 20 degree Western Mountaineering Bag. But I am not sure if this will be overkill with my bivy sack.
The quilt could work too, and the bivy traded for a groundsheet for the summer.
What do you guys recommend? If you have other suggestions besides those, by all means…
