Marmot Couloir 0-degree bag, used about 20 nights and washed once with REI down soap. It hasn't been slept in since it was washed.
Left zip, regular length (6'), 800 fill down, 3 lbs, 3 oz
$300 w/free western MT delivery along I-90 corridor or add $10 for shipping.
It's great! I used it in low temps in the Idaho backcountry in November, I just ended up with a Western Mountaineering bag so I don't use this one anymore.
