SOLD - I have a "like new" Warbonnet Yeti Underquilt, 3 season version up for sale. I purchased it late in the Fall of 2010, and have used it twice (ie, two nights). Both times were in the back yard - no smoke, no pine needles, no rain, no bird droppings, etc.
There is absolutely nothing wrong with the Yeti; it's in top condition and toasty warm. I've just decided I don't like messing with a 3/4 length UQ and a closed cell foot pad.
Asking $160; includes stuff sack and shipping in continental USA. First "I'll take it", gets it. SOLD
