I've got a 2 year old, used 1x BD Twilight Bivy for sale. $75, buyer pays shipping.

Found that I use my single wall tent more than a bivy. Sat in the gear closet after one chilly winter bivy.

Also have a pair of Yates Speed Wall Aiders for sale. Well used but plenty of life left in them. $40 for the pair, buyer pays shipping.
