Behold the king of all bivy sacks- the Black Diamond/ Bibler Made in USA waterproof alpine hooped bivy sack size large.

This is the bombproof seam sealed bivy sack made by Bibler just as they were bought by BD- hence both brands listed. Sleep tight on your next alpine mission in this shelter knowing you won't roll off your tiny ledge with the attached anchor loop.

Lots of life left in this sack. It would also make an excellent bike packing shelter for cool rides through Morocco or the Silk Road etc. For those less fearsome nights, keep the bugs off your face with the bug netting.
