hi folks 
  I have been looking at bivi's for a long time.  I have had my eye on the OR Adv and Bibler tripod. 
I will use it about once a month all 4 seasons rain or shine.  So it needs to be 4 season and preferabley breathable.  Id like it free standing because i sometimes camp in sand or on rock in the Sierra's.  needs to light.  On those 50 miles weekends.  4 pounds tent does not cut it. 
I camp all over the mid west and pacific coast.  In the sand. 
Thanks for your time
