B.A.T. Hammock

Designed by Warren Harding and Roger Derryberry, the B.A.T.hammock and B.A.T.tent were two of the first commercially available bigwall bivy systems. The hammock hangs from a single point and has no built in adjustability.
Warren Harding was known for his remarkable ability to suffer through incredibly strenuous climbs, often for many days, and this hammock design represented a significant improvement over sleeping while hanging in slings or belay seats. Although cramped and uncomfortable by later standards, this was a necessary step in bigwall evolution.

B.A.T. stands for “Basically Absurd Technology” and the equipment was manufactured by Denali Co. Inc.
This hammock and etriers were made in the early to mid 1970s.
