Tarp or Tent? Tarps and bashas are OK but their use is very dependant on the terrain and weather conditions. If you choose a tarp in poor weather conditions then you are in for a miserable night. For increased protection a bivvy bag and Mosi net is usually required. By the time you've added the weight of these additional items including cordage and pegs you may have as well brought along the tent instead. A tarp tent may possibly be the answer depending on your requirements.
