In reply to Removed User:
have used a henessy but only in warm/tropical areas. certainly good for that.
have my doubts about winter use. even if they handle the cold theyre not that great to hang about in (excuse the pun), cant realisticly cook in one, cant get dressed inside, limited gear storage.
to get around all that youd need extra poles etc so may as well take a tent. tho thered be an advantage in not having to clear the ground.
but for warmer stuff, yeah, good idea. good in wet areas.
if you get a henessey get the snake skins with it. fabulous idea.
