marmot alpinist bivy-will sell or possible trade?

[ruthslp]

hi, I tried to use the bivy bag just once & although the waterproofness was great, I have trouble sleeping with my head exposed & it's too stuffy when zipped up.

Would sell for $100 (& shipping) or a possible trade for other sleep item/gear?
